Peucedanum verticillare (3lt)

Giant Hog Fennel. This is a huge, stately umbellifer with stout purple stems and purple tinged sheaths that unfold to reveal large airy heads of greenish white flowers in summer. Delicate, cut glaucous green leaves. Height and spread to 2m x 1m. Short lived perennial but comes true from seed. A plant to impress given space.
