Begonia mananjabensis, a newer species to cultivation from Madagascar with pinnate leaves.  As with most flora and fauna in Madagascar, even if it’s not on the IUCN Redlist as Endangered, it should be treated as such.  I only have a limited number of these available this year.  Please try and spread this one around as best you can! Available plants are seed grown and rooted in 2″ pots.  It can reach 10-12″.
