Caryopteris × clandonensis 'Heavenly Blue
A lovely compact shrub that is well suited to a smaller garden or patio pot. The grey-green leaves are attractive in their own right, as a nice bit of structure in the garden. Come late summer and early autumn the plant bears dark blue flowers that cover the plant.
Grows to 1m and will spread the same
Is happy in most soils and prefers full sun.
