Katie Ferguson of Texas found this dwarf form of our native ruellia, and it took Texas by storm, although nothing like the really big storms such as Ike, Brett, and Alicia. Ruellia 'Katie' makes a 6" tall x 12" wide clump with lance-shaped green leaves. All summer, it is covered with 1.5" purple flowers. In good soil, it will reseed true. This is one fabulous plant!
