Genlisea oligophylla

May 2020

Genlisea is one of the least grown genus of carnivorous plants. Part of it is due to the rather unimpressive aerial parts, but also to their particular, semi-aquatic ecology. On the other side, the underground corkscrew structures are a real curiosity, and getting to actually see them was my main incentive to try and grow one of these plants.

Here comes Genlisea oligophylla, a recently described corkscrew plant from Serra do Cipo, Minas Gerais, Brazil. I chose a (moderately) highland species to best match the conditions of the room where my terrarium is installed. This excludes most, if not all, African Genlisea. The pretty flowers of G. oligophylla sealed the deal.

Using a customized net pot and a vase, I’m trying to achieve something similar to Geoff Wong’s clever and classy setup, that you can see here. I’m sure you’ll notice I left the classy part aside, but the principle is there and hopefully it will work out!

And there it is. To preserve the sphagnum moss from decay, the lower portion will not be submerged permanently.

The bottom structure of the pot retains the sphagnum moss, while allowing the future traps to get out and dive into the water.
