Rich green with a dusting of grey, feathery, aromatic foliage culminates in creamy button flowers in mid and late summer—an elegant aristocrat of the genus. It makes a pretty but serviceable matrix in an herb garden or sunny perennial bed. Trim when flowers are spent and lean, well-draining soil is the order of the day. Evergreen!
