Drosera spiralis

April 2019

A small population of gnats has seen the light of day in the terrarium. It is great to see the plants get their food “naturally”. They also prevent the tank from being completely infested.

Sundews are inherently very effective at catching flying insects. While they can fly away from the top of a pitcher, they are doomed right at the moment they touch a Drosera leaf. Not to mention the very attractive mucilage.

Both Drosera spiralis have been capturing a generous amount of gnats since their inception. What bugs me is that, due to too little air movement within the terrarium, most gnats mold after a couple of days, which I suspect hinders the digestion process.

Gnats are suitably sized for most sundews.

The plants took their time to settle, and are only starting to make slightly longer leaves than when I received them. Also, I cannot get them to produce more mucilage than what we can see on the photo.

When winter takes its toll on outdoor vegetation, ever-growing plants are a blessing!

Drosera spiralis is a more interesting Drosera filiformis with an intriguing name. That was my first thoughts when I discovered this species. Why more interesting? Because it has a very peculiar way of unfolding the leaves, that looks like a more complex variant of the usual circinate type. I will photograph it, but for now, the leaves are way too small to fully appreciate their development.

As far as I know, D. spiralis was rare to non-existent in collections before 2010. It has then spread rather quickly. I received two specimens from Damien Jouen, a French grower from forumcarnivore.org, and as per their tropical origins, they took place in my terrarium.
