Family

Asteraceae

Botanical Name

ECHINACEA augustifolia

Plant Common Name

Blacksamson, Blacksamson Coneflower

General Description

Blacksamson is an herbaceous perennial with a compact, upright habit. It is native from southern Canada to the southern United States and has hairy stems that arise from a basal cluster of hairy, lance-shaped leaves. In midsummer it bears large flowerheads with an orange to brown central disc, or cone, surrounded by pink or purple petals. A rare white flowered cultivar is also in cultivation. Like most coneflowers, these blooms are frequented by butterflies and bees, and their dry, seed-filled cones are feasted upon by seed-eating birds.

Blacksamson must have full sun and well drained, fertile soil. It shows great adaptability and will grow in both dry and sandy soils as well as the heavy wet soils. This coneflower is rarely used in the garden, because more colorful and robust species are favored, but it is a species used medicinally, so it may be a great choice for the herb or apothecary's garden.
