I bought a couple tropical terrestrial bladderworts a few months ago and they have been spreading through my carnivorous plant collection since. They seem to like any spot with a little bit of water. One of the smaller ones, Utricularia sandersonii, bloomed for the first time the other day. It is a carnivorous plant native to South Africa with flowers that are relatively large compared to the tiny leaves.
The upper petals have been described as looking like “bunny ears”, although they are not very distinct on this plant.
