Hi guys,
Great pics Sebas!! congrats on getting these plants to flower. You have a really cool G.hispidula. Somebody recently posted here or on the CPUK forum a comparison between 3 G.hispidula from different locations. The differences were surprising, did you see it?
As for the otehr 2 species, you seem to have the right stuff. Tamlin, G.repens never grows as an annual as far as I've seen. It always occurs in very wet habitats, usually submerged in shallow water year round.
As for G.pygmaea... I'm still not sure if it si an annual in the wild or if it goes dormant in the dry season. Apparently in cultivation it is perenial, right Sebas?
Take Care,
