Native to the sea coasts of Honshu, Japan, this umbellifer (carrot family) has proven to be a great bold-textured garden specimen, forming an 18" tall x 3' wide basal rosette of glossy dark evergreen leaves. After a couple of years, an ashitaba rosette is topped with a thick 5' tall spike of upright-facing large white umbels in mid-July. After flowering, the clump goes dormant until late fall when it emerges and subsequently remains evergreen through the winter. Angelica keiskei is used medicinally as a diuretic and health food as well as to prevent heart attacks and cancer...a regular renaissance plant.
