I'm propagating crypts to pass on to other growers to keep them in the aquarium hobby and building a resource to help with identification. I'm always looking to buy or swap for new varieties to grow.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.comBlogger35125tag:blogger.com,1999:blog-1282144163159058674.post-65361178102761736832021-07-12T18:42:00.047+10:002023-01-10T18:38:28.949+11:00Cryptocoryne x purpurea (Dennerle)<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ5lFLptZm9PibxOOgdJebnT0GSj2D8OEFN60P7gIZGhWsehLqTYwkPtnkdsLs98plfHrDBldkFOeBdnQDrnbAN6uU0UbGfgLgEYJWQryJk9iuXoa04mjLzyfPVGn47SRJB2jSZsnRwt79Ex3bN25Aj4o5DUitnOCReUpammuVUtf5auP2deRAEvmo/s800/Cryptocoryne%20Cordata%20var%20Dennerle%20xpurpurea%20spathe.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Cryptocoryne x purpurea (Dennerle)" border="0" data-original-height="800" data-original-width="600" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiZ5lFLptZm9PibxOOgdJebnT0GSj2D8OEFN60P7gIZGhWsehLqTYwkPtnkdsLs98plfHrDBldkFOeBdnQDrnbAN6uU0UbGfgLgEYJWQryJk9iuXoa04mjLzyfPVGn47SRJB2jSZsnRwt79Ex3bN25Aj4o5DUitnOCReUpammuVUtf5auP2deRAEvmo/s16000/Cryptocoryne%20Cordata%20var%20Dennerle%20xpurpurea%20spathe.jpg" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilc_Ooo5YRgS3PZfFVGbDcXP70poP8oo5icHpLp9x7ZnJJO3qc7Jhr7OunqI0mAEu4rgGkP6l02yxYCdGheUikdFA3f92g9RnFhEXb0eFUgUmRRfDPzyeUIfwcukpk0dNnzl3zmIjXlOu5iW6yfgKtC4FE3z5i5BWvCKrQ6Z-3KwHdFyJ_9CVG3tGq/s800/Cryptocoryne%20xpurpurea%20Dennerle.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Cryptocoryne x purpurea (Dennerle) spathe" border="0" data-original-height="800" data-original-width="600" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEilc_Ooo5YRgS3PZfFVGbDcXP70poP8oo5icHpLp9x7ZnJJO3qc7Jhr7OunqI0mAEu4rgGkP6l02yxYCdGheUikdFA3f92g9RnFhEXb0eFUgUmRRfDPzyeUIfwcukpk0dNnzl3zmIjXlOu5iW6yfgKtC4FE3z5i5BWvCKrQ6Z-3KwHdFyJ_9CVG3tGq/s16000/Cryptocoryne%20xpurpurea%20Dennerle.jpg" /></a><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiw-IsTNgB6q-P__65Pzz16eM9yvIcPaBhjfQvn8qAE6GRw1gkk6h3FnGSC8FgNnIhGzRBEsvcXkvx6Jf4rgKBqctzhV-RztSIHp_d7YiStElhgw_8UsVPs55zLZe3mWdDMY1wON9-m_UxsQFvVJlKWl_5qQN239HwGOwlVQyuTX35T6tMRXKvhFYUX/s800/Cryptocoryne%20Cordata%20var%20Dennerle%20xpurpurea%20spathe%202.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Cryptocoryne x purpurea (Dennerle) in aquarium" border="0" data-original-height="800" data-original-width="600" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiw-IsTNgB6q-P__65Pzz16eM9yvIcPaBhjfQvn8qAE6GRw1gkk6h3FnGSC8FgNnIhGzRBEsvcXkvx6Jf4rgKBqctzhV-RztSIHp_d7YiStElhgw_8UsVPs55zLZe3mWdDMY1wON9-m_UxsQFvVJlKWl_5qQN239HwGOwlVQyuTX35T6tMRXKvhFYUX/s16000/Cryptocoryne%20Cordata%20var%20Dennerle%20xpurpurea%20spathe%202.jpg" /></a></div></div><br /><p>Dennerle describe this variety as:</p><p> " a natural hybrid between <i>Cryptocoryne griffithii</i> and
<i>Cryptocoryne cordata</i>. The variety described here comes from Borneo and has remarkable marbling on the leaf blades."</p>Not to be confused with <i>Cryptocoryne purpurea</i>
which is a very different species of Crypt. "Purpurea" is from the
latin for purple and I have seen this plant growing in conditions where
the mottling on the leaves takes on a distinct purple hue... or perhaps
its named for the colour of the limb on the spathe *shrug*. Its doing
very well in this 45cm cube tank with a substrate of aquarium sand mixed
with a little red clay and a fist-full of aquasoil. I find its is very
slow to get established - but once happy it will take off and spread
via runners. The mottling on the leaves is more apparent in nutrient
stressed plants. The Cordata group often flower in deep tanks where the
spathes never break the surface of the water. This one is putting on a
good show at 36cm in length but I suspect its not going to get long
enough to reach the surface.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-49954686653133267852018-08-07T10:12:00.002+10:002023-01-10T19:10:47.936+11:00 Cryptocoryne cordata var. siamensis "evae" spathe in jar culture<div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar1.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="C. cordata var. siamensis 'evae' growing in a jar" border="0" data-original-height="800" data-original-width="600" src="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar1.jpg" /> </a></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="800" data-original-width="713" src="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar2.jpg" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" src="https://www.litepc.com/grubs/plant/crypts/cordata_evae_jar3.jpg" /></a></div><div class="separator" style="clear: both; text-align: left;"> <i>Cryptocoryne cordata var. siamensis "evae"</i> has been grown in Australia for decades. <i>Cryptocoryne evae</i> is an old names that is now considered a synonym of <i>Cryptocoryne cordata var. siamensis</i>.

I removed the bracing and rolled the tank onto its side so the opening is now on the front.<br /><br />A new piece of polished glass is siliconed across the bottom of the opening to hold the water. The opening is closed off by a piece of twin-wall polycarbonate with a couple of cable grommets installed as vents and handles. On a hot day the afternoon sun through the window was pushing the air temp to 40+C before the vents were installed. Some corrugated translucent polycarbontate sits between the tank and the window to diffuse the direct sun.<br /><br />To keep it neat and tidy I mounted the heater in a DIY PVC external enclosure in the cabinet. The base of the tank is drilled at each end and bulkheads are installed that allow a loop of 16/22mm hose lagged with closed cell foam to connect the tank to the heater chamber. It works by thermosiphon without a pump. Hot water rises from the heater into the tank at one end and cooler water sinks out of the bulkead at the other end of the tank and circulates back down to the heater. The heater is set to 20C.<br /><br />This new growing space replaces a couple of the polystyrene boxes I was using.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135926_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Large aquarium for growing emersed crypts" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135926_HDR.jpg" title="" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135936_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Large aquarium for growing emersed crypts" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135936_HDR.jpg" title="" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135839_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135839_HDR.jpg" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135852_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Large aquarium for growing emersed crypts" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135852_HDR.jpg" title="" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135829_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="lots of emersed crypts" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135829_HDR.jpg" title="" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135801.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_135801.jpg" width="640" /></a></div><br /><a href="https://www.litepc.com/grubs/plant/crypts/20171103_135736.jpg" style="margin-left: 1em; margin-right: 1em;"><img alt="external DIY heater chamber made from PVC pipe" border="0" data-original-height="800" data-original-width="600" height="640" src="https://www.litepc.com/grubs/plant/crypts/20171103_135736.jpg" title="" width="480" /></a>Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-39424203734237216742017-11-01T00:35:00.002+11:002020-04-20T23:10:59.516+10:00The "Baptism Tub" CryptariumA church was selling this "Baptism Tub" on ebay- its a big industrial plastic tub that I've put on a base of milk crates with a timber frame around it to stop it bowing out from the pressure of the water inside. I'm growing crypts on a row of inverted milk crates inside the tub. This allows the tub to hold a large volume of water to help stabilise the temperature. We have vary variable weather here and my glasshouse temperature fluctuates wildly and can get screaming hot in summer. A sheet of greenhouse plastic over the top keeps the warmth and humidity in while its cool... but in summer I'll switch to shadecloth so it breathes a bit better and I have some misters on a timer to cool the air down. In winter I'll have to put a heater in the tub as its common for the water to get below 7C.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_140100_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="a big tub for growing emersed cryptocoryne" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_140100_HDR.jpg" title="" width="640" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_140614_HDR.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="a big tub for growing emersed cryptocoryne" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_140614_HDR.jpg" title="" width="640" /></a></div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20171103_140147.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="emersed cryptocoryne growing in a big plastic tub" border="0" data-original-height="600" data-original-width="800" height="480" src="https://www.litepc.com/grubs/plant/crypts/20171103_140147.jpg" title="" width="640" /></a></div>Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-1212345293003715192017-10-04T16:26:00.003+11:002020-04-20T23:10:59.696+10:00Cryptocoryne crispatula var. balansae spathe<div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/crypt_balansae_spathe.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Crypt crispatula balansae spathe" border="0" data-original-height="800" data-original-width="600" src="https://www.litepc.com/grubs/plant/crypts/crypt_balansae_spathe.jpg" title="Crypt crispatula balansae" /></a></div><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/crypt_balansae.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Crypt crispatula balansae spathe" border="0" data-original-height="800" data-original-width="600" src="https://www.litepc.com/grubs/plant/crypts/crypt_balansae.jpg" title="Crypt crispatula balansae" /></a></div><br />This is an emersed pot of a generic <i>Crypt . crispatula</i> that came to me unlabelled so at some point I called it 'balanasae' on the basis of the submersed leaves.

It seems quite different to <a href="https://cryptocoryne-au.blogspot.com.au/2016/02/cryptocoryne-albida-costata.html" target="_blank">another Crypt. albida 'costata'</a> that I obtained from an Australian grower that has much fatter and more open spathes.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-89863180988719783402017-09-02T01:17:00.002+10:002020-04-20T23:11:00.296+10:00Cryptocoryne cordata var. siamensis "Red Giant"<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/crypt_cordata_siamensis_red_giant.jpg" imageanchor="1" style="margin-left: auto; margin-right: auto;"><img alt="Cryptocoryne cordata var siamensis 'Red Giant'" border="0" data-original-height="800" data-original-width="600" src="https://www.litepc.com/grubs/plant/crypts/crypt_cordata_siamensis_red_giant.jpg" title="Cryptocoryne cordata var siamensis 'Red Giant'" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"></td></tr></tbody></table>I was lucky enough to score a piece of this Crypt from a local shop display tank. I normally use small 95mm square pots for my crypts but this was a big crypt so it went in a 150mm pot and is in a 600l 6x2x2 tank (sharing with some purple spotted gudgeons). Its a big crypt - currently 40cm tall and the biggest leaf blades are 20x7cm excluding the petiole. A few sellers in Australia recently have been selling a Crypt cordata named "Red Giant" so I'm assuming this is the same - the undersides of the leaves are very red. There are a few other similar plants in Australia at the moment: A Crypt cordata distributed by Dennerle, and another Dennerle variety sold as Crypt. x purpurea but clearly both are varieties of <i>Crypt cordata var. siamensis.</i><br /><i><br /></i> <i>"To make a long story short: almost all Cryptocoryne cordata plants in our aquaria today belong to var. siamensis. If you have it growing successfully in your aquarium there is a more than 90% chance that it is var. siamensis. And even if it is not growing well, there is probably still a more than a 90% chance that it is var. siamensis. If it were one of the other varieties of Cryptocoryne cordata it would most likely be dead by now. Of course, if you are one of the few people keeping aquaria with a pH of 4 – 5, you may have something else, but even then there is a good chance that you may have var. siamensis."</i><br /><br /><i>Jacobsen, N., and Bastmeijer, J.D. 2014.

One stem has rotted without shooting. The other stem threw a couple of leaves then stopped and also rotted (the big leaf), but the other end of the stem has now shot again so fingers crossed. The media is plain peat moss and sand watered by rainwater (pH 5.5 to 6.0) to provide acidic conditions. I put some alder cones in the water to push the pH down a bit lower but they don't seem to have much effect. I've tried oak leaves and beech leaves so far but still only getting pH down to 5.5 to 6 and I think I need to push it a bit lower (more acidic).<br /><br />Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-86530696467799601542017-09-01T01:28:00.002+10:002020-04-20T23:11:00.687+10:00Cryptocoryne aura<div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/crypt_aura.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="640" data-original-width="614" height="640" src="https://www.litepc.com/grubs/plant/crypts/crypt_aura.jpg" width="614" /></a></div>Discovered in 2014 and described only last year. <br /><div class="csl-bib-body" style="line-height: 1.35; margin-left: 2em; text-indent: -2em;"> <div class="csl-entry"><a href="http://www.bioone.org/doi/abs/10.3372/wi.46.46209" target="_blank">Wongso, S., Ipor, I.B., Tawan, C.S., Budianto, H., Bastmeijer, J.D., and Jacobsen, N. 2016.

Hopefully not too little too late. I know nothing about <i>C. ferruginea</i> other than what I can find online.<br /><br />From Ipor et al (2006), it is naturally found in acidic conditions with pH 4.6 to 5.5, likes very soft water and shaded conditions.<br /><br /><br /> I loosely bedded the stalks into a mix of sand and composted oak leaves and flooded them with pure rainwater (pH 5.5-6.0, EC 10-20 µS/cm) to the depth you see here. There is a bit of soil in the leaf mix that is initially causing the pH to rise, so I've been draining the pot and reflooding with fresh rainwater every couple of days to maintain acidic conditions. I'm waiting on fresh supplies of peat moss and I may switch them over to a fresh mix with more peat if the pH keeps going up.<br /><br />Fingers crossed.<br /><br />Further reading: Ipor, I. B., C.

Hats off to anyone that achieves this as Crypt parva is a very slow grower so you need patience or to invest in buying lots and planting heavily at the outset. I've seen people closing down a tank sell chunks of "carpet" afterwards for $100+ to be snapped up by the impatient.<br /><br />The top photo is a slightly manky lunchbox of Crypt parva in one of my tanks. I plant parva around the base of my Aponogetons as it looks good and stops the fish scattering the gravel. Some people think the Crypt roots help oxygenate the substrate. Perhaps thats true... but in this case the Aponogeton died leaving me with a nice crop of parva about 1cm tall. I took a few plants and put them in a pot to grow emersed and they took off.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/crypt_parva_emersed.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Crypt parva emersed" border="0" src="https://www.litepc.com/grubs/plant/crypts/crypt_parva_emersed.jpg" title="" /></a></div><i><br /></i>If you didnt know better you might think the emersed plants are one of the <i>Cryptocoryne </i>×<i>willisii</i> group that is well known for the characteristically lanceolate leaves on long petioles, or even a dwarf <i>sagittaria</i>. The substrate mix is nothing special - sand, peat moss, and a handfull of shell grit to buffer the pH and add calcium and a handful of composted oak leaves for nutrition<br /><br />Last year I lost my emersed Crypt parva in winter - tough love in a cold climate. This year the heaters are in early.

Although they are now considered the same species, there can be subtle differences in the varieties that warrent keeping them separate in cultivation. For this reason the full name of the 'blassii' variety is <i>Cryptocoryne cordata var. siamensis 'blassii'</i> and therefore this 'evae' plant is <i>Cryptocoryne cordata var. siamensis 'evae'.</i><br /><br />Confusion in crypt taxonomy is not a new thing and there is more than one online database that still uses the "evae" name.<br /><br />The source grower thinks the underside of the leaves may be paler red (more green) when compared to <i>blassii</i>, but that could also result from growing conditions (and that red leaf bottom left looks very much like my <i>blassii</i>). I'll grow <i>evae</i> side-by-side with <i>blassii</i> and see if any differences are maintained.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-12533685591602601562017-04-05T12:52:00.002+10:002020-04-20T23:11:01.475+10:00Cryptocoryne moehlmannii<div class="separator" style="clear: both; text-align: center;"><img alt="Cryptocoryne moehlmannii" border="0" src="https://www.litepc.com/grubs/plant/crypts/crypt_moehlmannii.jpg" title="" /></div><div class="separator" style="clear: both; text-align: center;"><img alt="Cryptocoryne moehlmannii" border="0" src="https://www.litepc.com/grubs/plant/crypts/crypt_moehlmannii_top.jpg" title="" /></div><div style="text-align: left;">Crypt. moehlmannii looks similar to Crypt. noritoi and Crypt. pontederiifolia so really need to make sure they are labelled clearly.

Leaf mould is just the humus from composting leaves. A few initial trials on emersed varieties of Crypt. undulata have been really good with improved growth rates and healthier looking leaves over just using peat moss and sand. The leaf mould starts as raked up oak leaves in a cut down barrel that has no bottom where they compost down. I keep adding to the top and stiring it occasionally. When its ready I pass the broken down leaves through a 5mm garden sieve, keeping the smller fraction and returning bigger leaves to the barrel.<br /><br /><div class="separator" style="clear: both; text-align: center;"><img alt="Oak leaf mould made from composted oak leaves" border="0" src="https://www.litepc.com/grubs/plant/crypts/oak_leaf_mould.jpg" title="" /></div><br /><br />I've been using the oak leaf mould to replace some or all of the peat moss in a mix that is about 40% peat/oak, 50% sand and 10% red clay and shell grit. We don't have many "blackwater" crypts in Australia that grow in pure leaf mould, but if they ever get here I'm ready.<br /><br /><b>Update: May 2017. </b> The pH of the mix is approx 7.2 so not acidic at all and not the best for the true blackwater crypts. I certainly do think its benficial to the mix, but for species that need pH <6.0 this isn't going to do it... at least not in the form it is here. I've got some in jars with Crypt cordata that have been festering as a slurry with water for a longer period of time and these are more acidic. It might take a couple of months in water for the organic acids to really do their thing.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-39784421963892720032017-03-28T23:12:00.005+11:002020-04-20T23:11:02.833+10:00Cryptocoryne pontederiifolia<div class="separator" style="clear: both; text-align: center;"><img alt="Cryptocoryne pontederiifolia" border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115449.jpg" title="Cryptocoryne pontederiifolia" /></div><br />Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-45876591726828025652017-03-28T23:09:00.004+11:002020-04-20T23:11:03.048+10:00Cryptocoryne ciliata var. latifolia<div class="separator" style="clear: both; text-align: center;"><img alt="Cryptocoryne ciliata var. latifolia" border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115730.jpg" title="Cryptocoryne ciliata var. latifolia" /></div><br /><div class="separator" style="clear: both; text-align: center;"><img alt="Cryptocoryne ciliata var. latifolia" border="0" height="480" src="https://www.litepc.com/grubs/plant/crypts/20170328_115721.jpg" title="Cryptocoryne ciliata var. latifolia" width="640" /></div><br />New runners and hopefully a flower forming. Crypt ciliata in the wild is more of a brackish mudflat plant so tends not to be common in aquaria. I have one submersed also but its nowhere near as healthy and vigorous.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-82664350707946081402017-03-28T15:44:00.002+11:002020-04-20T23:11:03.266+10:00End of summer 16/17Photo update of my emersed crypts before I move them from their suymmer "shed" back to the glasshouse for winter. The boxes are slowly multiplying - my goal is to have a couple of pots of each variety and after that any extras I can propagate will be distributed to other collectors first (off-site backups!) and then to whomever shows an interest. There are 4 tanks of submersed crypts inside too. OTT? maybe.<br /><br /> <img border="0" height="480" src="https://www.litepc.com/grubs/plant/crypts/20170328_115120.jpg" width="640" /> <br /><img border="0" height="480" src="https://www.litepc.com/grubs/plant/crypts/20170328_115346.jpg" width="640" /> <img border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115235.jpg" /><br />Above: Mostly <i>Cryptocoryne undulata</i> varieties in a new potting mix that is working really well (sand, clay, peat, a handful of shell grit, and composted oak leaves) - notice the dark greens. Growth has been great in these pots and I think composted oak leaves have improved the mix.<br /><img border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115243.jpg" />Above: Older pots (a little yellowing suggests more ferts needed) mostly <i>C. wendtii</i> to the left, <i>C. cordata</i> to the right, <i>C. albida</i> varieties in the back, <i>C. crispatula var. kubutae</i> is the grassy one in the middle.<br /><br /> <img border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115258.jpg" /><br />Above: Mostly <i>C. spiralis</i> in the back (lots of flowers at the moment but not really visible in the pics), <i>C. crispatula</i> varieties in the front. Again notice the yellowing of some of the plants suggesting the nutrients in the pots are exhausted - crypts are heavy feeders and these post have been going for more than a year. I've started putting just a little of my aquarium fert and trace mix into the water.<br /><br /> <img border="0" src="https://www.litepc.com/grubs/plant/crypts/20170328_115307.jpg" /><br />Above: Bits of this and that - <i>C. wendtii</i> varieties in the back, <i>C. crispatula var balanasae</i> poking through...

I have one submersed also (not going so great but stable). It looks like I have some runners forming and also maybe... a flower! I love the hairy flowers from these and have not seen one that was grown in Australia before - see pics on<a href="https://crypts.home.xs4all.nl/Cryptocoryne/Gallery/cil/cil.html" rel="nofollow" target="_blank"> the Crypt Pages</a> Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0tag:blogger.com,1999:blog-1282144163159058674.post-86017314418464461632017-01-13T22:49:00.002+11:002020-04-20T23:11:03.444+10:00Cryptocoryne crispatula var. flaccidifolia vs. Cryptocoryne crispatula var. balansae<div class="separator" style="clear: both; text-align: center;"><a href="https://www.litepc.com/grubs/plant/crypts/20170103_130731.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img alt="Cryptocoryne crispatula var. flaccidifolia and balansae" border="0" height="480" src="https://www.litepc.com/grubs/plant/crypts/20170103_130731.jpg" title="" width="640" /></a></div><br />What I am calling <i>Crypt. crispatula var. flaccidifolia</i> (left) vs <i>Crypt. crispatula var. balansae</i> 'red stem' (right). Ive grown the flaccidifolia for over 10 years thiking it was a limp variety of balansae. Some people also grow a similar looking palnt and call it <i>C. retrospiralis</i> but based on <a href="https://crypts.home.xs4all.nl/Cryptocoryne/Gallery/ret/ret.html" rel="nofollow" target="_blank">the description for <i>C. retrospiralis</i> on the Crypts pages</a> I think this is incorrect. The characters that distinguish it are the limper leaves (more flaccid!) and the undulating margins of the leaves compared to the balansae that usually has a straight margin and bullate blade.<br /><br />There are a number of varieties of <i>Crypt. crispatula var. balanasae</i> in Australia - this one is the 'red stem' variety where the petioles and central vein can be quite a dark red. There are others with creamy white petioles and veins that I unimaginatively call <i>Crypt. crispatula var. balanasae</i> 'green' to distinguish it.Grubshttp://www.blogger.com/profile/06786733434690688542noreply@blogger.com0
