This small trailing begonia has ruby red stems and nice speckled leaves.  The underlying leaf color is a greenish purple, and speckling is a much lighter silvery-green.  Leaves stay around an inch and maintain nice compact growth across the substrate. U074 has been tentatively identified as Begonia nigritarum, however, there does seem to be some variation between the two.

Available plants are well rooted in 2″ pots.  They will be shipped potted.  The last photo is representative of the size plant you will receive.
