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 unusual small flowers (Bishop’s Hats) are held above the foliage in airy sprays, and resemble miniature Columbines. Reliable and long-lived, Epimediums can adapt to drier conditions once established, spreading slowly and steadily. Both flowers and foliage are prized for small arrangements.
Though this Epimedium grandiflorum and Epimedium pinnatum ssp. colchicum hybrid was selected well over 150 years ago, it still upholds an impeccable long-standing reputation as the go-to Epimedium for difficult shady garden recesses. The suave, closely hewn ground covering clump is described by trim bright red flower stalks plus sprightly pale yellow ornate blossoms above leathery heart-shaped green leaves, donning artful wine-hued etchings in spring and autumn maroon blotching. Fast growing, energetic and swarthy, ‘Sulphureum’ mingles well with early blooming Pulmonarias or Brunneras, while conquering a wide range of soil.
