Top Plants For Sonoma County
Cut back in early spring to renew.
Lacy gray-green, finely divided foliage stands out from stout stems rising from a woody base. Lavender blue airy flower spikes on branch tips erupt into bloom in summer and last for months. In winter, stems become silvery white, a standout in the landscape. Plants withstand cold but can be damaged if pruned before the last frost when they should be cut to about 6 inches. Unpruned plants become unstable and subject to breakage. Provide good drainage but withhold fertilizers and all but light summer irrigation. Dwarf cultivars are available.
