One of the slowest Sonerila I have grown, even slower than the lobe species in my experience.  Foliage is thick and succulent and the tallest any of mine have reached is about 4″.  Doubtful they reach more than 6″. This species is native to Indonesia, but I’m not sure where exactly.

Available plants are well rooted in 2″ pots and will be shipped meticulously in their pots.  The last photo is representative of the plants available.
