Dormancy or not?

[jimscott]

From a website:

The Drosera x tokaiensis, a very close relative of the Drosera spatulata, is a subtropical sundew that is easy to grow, likes bright indirect light, and does not require a dormancy.

Grow it in a sunny windowsill or under fluorescent lights year round. It does well adjusting to lower humidity levels found in the home.

For me, sometimes some of the plants would have a sort of winter dormancy, the length of the petioles becoming reduced and aggregated loosely in the center of the plant: not true hibernacula as in D. rotundifolia. Best kept cool if this happens, but not frozen or they will die, They look pretty sad when it happens and are weak. Sometimes they would recover, sometimes not. I assume the differing genomes in different plants are why some do and some don't. Never force the issue, just cooperate with whatever the plant does, reducing water, maintaining good air circulation and good light if they seem to be petering out. Unless they go all black, they have a chance of returning if you do the right things. Always save your seed of this species!
