24-48" tall x 48" wide (cutting propagated). An outstanding new Blue Mist cultivar, 'First Choice' is different from other varieties because of its tight branching habit and deep, deep blue late-summer flower spikes. Caryopteris is also a superb shrub for providing nectar for butterflies and other pollinators. Plant in non-clay soils and irrigate deeply but infrequently. Trim back by 1/3 to 1/2 in the spring every third year. Deadhead annually in the fall or spring. I like it paired with white-flowered Fernbush.
