This is only photo update. I will write more later (or put it into separate posts). Recently I do not have much time. Sorry everybody, I have not answered comments, e-mails, or PMs (on other hobby servers). I got them, I will answer later. Summer is always busy – at least for me.
Despite my trials, despite my care, the plants grow. I keep these species for several months already. None of them flowered yet (correction – C. sp. ‘Yellow Ring’ flowered 2 times), but seeing how they grow make me happy. This post just photo documents the progress.
In some cases I got two plants per each species, therefore I tried different substrates (mostly based on beech tree litter/mould) and different setups to see in which it goes better. Here are the “pretty” looking plants. If you want to compare the size of leaves, the clay pots are 8/9cm wide.
Since there are a lot of pictures, a lot of species in one post, here is a a quick navigation:
C. affinis | C. bullosa ‘Sarikei’ | C. fusca | C. ideii | C. longicauda ‘Seri Aman’ | (?) C. minima ‘Perak’ | C. noritoi | C. uenoi ‘Serian’ | C. usteriana | C. x purpurea novothovar. borneoensis ‘Lundu’ | C. sp. ‘Yellow Ring’ ‘Bukit Ibam’ | L. meeboldii pink
I put C. bullosa in cover protected plastic pot and the humidity condensates all over so I cannot see through properly. I was surprised when I saw 3 new leaves with pretty vidid green color. The darker leaves are “import” leaves – from nature or farm. Another surprise were tiny bubbles. I suppose it is gas creating in substrate.
Another specimen is growing much slowly. This one is in pH approx. 4-4,5 and already has new plantlets. The same goes for following two species.
I am not sure, but when I look at the picture, it resembles me my C. x purpurea from Dennerle. It was labeled as C. minima ‘Perak’, but the leaf pattern confuses me. Lets wait for a spathe.
Another specimen is growing much more slowly. Maybe it is because of higher pH. Anyway, I started to lower pH in most of my tanks. I am curious about the results. Here is the picture.
I also have several of these usteriana(s) in my fish tank. The leaves were getting larger, were becoming bullated and I could see the reddish color on their underside. Unfortunately it all melted down several days ago… so the pictures of submersed plants…maybe next time.
I have seen plenty of pictures of emersed C. usteriana, but still – I was surprised how easily it grows.
When I got this Crypt, I was a little bit worried because it was kind of pricey, but it grows really well.
I have several pots of C. sp. ‘Yellow Ring’ and it flowers regularly. Here are some pictures.
These plants are not rare, but I add them to the post.
Just in case someone is interested, here is my pot with common C. affinis. It is covered with lid, so the humidity goes high.
L. meeboldii has actually much prettier color, but the leaf surface makes kind of reflection and it is changing from brown to pink. You can see some pink color in the picture, but not as much as you would in reality. The picture shows large leaves, but in my conditions it often melts down.
Last week I paid a visit to my friend. He has got several tanks but what amazed me the most was the one with his Cryptocoryne affinis.
We can say it is a common Crypt that almost everybody had in his tank 10 or 15 years ago. But since it is quite hard to cultivate it in emersed setup (and submersed cultivation would be expensive), the plant nurseries supply this Crypt almost rarely. And that is a pity! See the picture to understand why. The photo is from his 10 or 15 years old – and still running – tank. Simple tank with quite large gravel (but to be honest well nutritioned by fish…), sponge filter with power head and some blue-ish tube above it (I will ask later what light did he use). The result – dark green leaves and I fell in love with them. I was told his affinis blooms quite often so I am looking forward to take a photo next time I have a chance.
Thank you, Karel.
