My Drosera capensis 'red' only achieve his best coloration under full sun. Even close under my fluorescent tubes, they can reach a pinkish tint, but nothing more. Perhaps my tubes are too old (I know they are, but i don't know much the effects on plants!).
Great plants PinguiculaMan, as usual!
I was wondering: You seem to use frequently this recipe (pure LFS with bark at the bottom of the pot), do you apply this unique recipe to all your sundews? One thing is sure, the contrast of yellowish green moss with red leaves is striking!
