Narrow dark green leaves to 3 in. long, 3/4 in. wide; 2-in.-long, lavender-blue flowers throughout the warm times of year. ‘Chi Chi’ has soft pink blossoms. ‘Katie’ is a dwarf (10–12 in.), noninvasive variety. ‘Blanca’ (white flowers) and ‘Rosa’ (pink flowers) have narrow leaves and grow to about 1 ft. high. Regular water.
