'Christy' forms low, attractive mounds of decorative highly serrated, fernlike foliage reaching a manageable 6-9 inches high and 16 inches across. The plant becomes covered with short flower spikes in late spring, and blooming continues sporadically throughout the summer and into the fall. The small- to medium-size blue-violet blooms have an attractive tiny white eye. If flowering wanes during the heat of the summer, the plants can be trimmed back to reinvigorate growth and flowering.
