General Information

Description
The best Caryopteris we’ve seen! Tight, compact growth with excellent branching. Dark, green glossy foliage.
Deep blue flowers are richer than other Caryopteris varieties, and will attract butterflies to late summer gardens.
Enjoy the rare blue color from late summer to fall. Perfect for use in the mixed border or perennial beds. May also be planted as part of a wildlife garden.

Growing Tips
Prefers well-drained, loose soil. Does not like to be oversaturated - good drainage is required. Prune in spring down to where new growth is sprouting. In Northern states, this plant will dieback to the ground though roots are hardy. In the South, cut back if needed. Trim to shape in late winter/early spring. Fertilize in early spring by applying a slow release fertilizer specialized for trees and shrubs. Follow the label for recommended rates of application.
