Berberidaceae
In the genus Caulophyllum are perennials from mountain woodlands in eastern North America and Japan grown for their attractive, 3-lobed leaves and blue seeds that resemble berries or small grapes. When leaves first emerge they are purple. The flowers are small, but rather unusual looking. Blue cohosh (C. thalictroides) was used medicinally by the Native Americans for a number of ailments. Grow Caulophyllum in a woodland garden.
Noteworthy characteristics:  Pleasing foliage and blue berry-like seeds.
Care:  Grow in part of full shade in moist, organically rich, acidic soil.
Propagation: 

<em>Caulophyllum</em> are slow growers and seed germination may be erratic. Divide before growth begins in spring or after flowering, or sow seeds in an open frame as soon as ripe.
