31/2-4' x 4' 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. Blooming after 'Longwood Blue', plant them both to have several months of flowering. Caryopteris is also a superb shrub for providing nectar for butterflies and other pollinators. Plant in non-clay soils and irrigate deeply but infrequently. I like it paired with white flowered Fernbush. Zones 5-9.
