Three dwarf forms of T. s., which do not bloom for me. Their leaves are about 1/2 the length of the larger kinds which flower regularly. Plant on the left is T. s. 'Hawaiian Dwarf' or 'Tricolor', one in the middle is T. s. 'Sitara Gold', and don't know of any varietal name for the one on the right.

I'd like to hear if others have had luck with flowering of these dwarf ones. Yale
