This wonderful dwarf Ruellia was found by Texas plantsfolk Katie Fergerson and Lynn Lowery. Dark green lance-shaped leaves are beautiful on their own, and are topped by 1.5" violet-blue Petunia flowers from June until frost. Little 'Katie' is remarkably versatile, growing in full sun to light shade, wet or dry conditions. Useful as a groundcover, edging or even as a marginal water plant. Unlike the straight species, this Ruellia is well-behaved, perhaps seeding in, but not aggressive. May overwinter in Zone 7; even if not, a delightful tropical annual.
