Blue mist shrub (Caryopteris x clandonensis) produces bushy plants typically 3 to 4 feet tall and wide, with aromatic, gray-green leaves and whorls of blue flowers that bloom in late summer to early fall. Commonly grown as a perennial but technically a deciduous shrub, it is a favorite with bees, butterflies, and other pollinators. The seedheads are somewhat interesting too, and if you leave them on the plant into the winter, you’re likely to find some self-sown seedlings in future years. I suggest cutting all of the stems back to about 1 foot soon after you notice new growth appearing in spring to keep established plants neat and bushy. Full sun. Zones 5 to 9.
Harvested in October 2020. At least 15 seeds.
