Epimedium

Barrenwort or Bishop’s Hat

Dense and leafy Epimedium is one of our most successful ground covers for the moist woodland setting. New heart-shaped leaves on wiry stems unfurl in spring with a rosy, marbled coloration that fades to green as summer approaches. In autumn, the marbling returns in coral and copper, enduring mild winters.

The tiny, unusual flowers (Bishop’s Hats) are held above the foliage in airy sprays, and resemble miniature Columbines. Durable and long-lived, Epimediums can adapt to drier conditions once established, spreading slowly and steadily. Both flowers and foliage are prized for small arrangements.

Eryngium

Dynamic is a rare adjective to apply to a plant, but it’s the best we can think of to describe Eryngium. From its leathery lobed leaves to the spiny, decorative bracts that host the flower, the Sea Holly has a sense of movement that is up and out. Excellent in fresh or dried arrangements, the flowers are borne on tall, branching stems, and the terminal blooms hold their color while lateral flowers develop, until the entire stem is covered with mature blossoms.

Eryngiums love well drained soil in the open sun, and are an arresting addition to the mixed border, especially when planted amidst Rudbeckia, the Achilleas, and grasses.
