Blue Cohosh is a native perennial which grows on strong, upright stems. It is valued for its lacy, ternately-compound, blue-green foliage and its erect clusters of blue, fruit-like seeds. Leaves appear at mid-stem, emerging a smoky blue in spring and turning bluish-green at maturity. Young plants are covered with a whitish, waxy bloom. Inconspicuous, brownish-green to yellowish-green flowers (1/2" diameter), each with six pointed sepals, appear in spring. Flowers give way in summer to attractive blue berry-like seeds which resemble small grapes and provide good ornamental interest into fall after foliage decline has occurred.
