Cryptocoryne thwaitesii
There are only a few crypts that I regard as standing out from the crowd, and Cryptocoryne thwaitesii is certainly one of them. The leaves have a rather leathery look to them and a sand paper like texture which is quite unique and distinctive. Besides the surface texture, the edges also are denticulate, in a rather regular manner – almost like little rectangular notches. Leaves also seem to have a metallic sheen, which really has to been seen to be appreciated.
Cryptocoryne alba and Cryptocoryne bogneri are closely related to this species. Of these three, Cryptocoryne thwaitesii is considered to be moderately difficult to cultivate. It requires water with low TDS and electrical conductivity, but not a very low pH.
I received a plantlet from a friend of mine back in January of 2008. After a short period of growth, much to my dismay it promptly melted away. I kept the pot, hoping that it would come back, and sure enough, about a month later, I saw the tiniest of growth – a small leaf – no longer than 2 mm. The plant grew slowly at first, but as the leaves got larger, the growth rate increased dramatically. Last week, I noticed two spathes starting to come up. This is the first one. Enjoy the pictures! I know you’ll agree – its a beautiful plant!
