Epimedium grandiflorum (large flowered barrenwort, bishop's hat) is a species of flowering plant in the family Berberidaceae, native to China, Japan and Korea.[1] It is known as dâm dương hoắc in Vietnamese.


It is a deciduous perennial growing to 30 cm (12 in), with bright red stems with green heart-shaped leaves (copper-tinged when young) which are slightly hairy on the bottom. In spring it produces pink, white, yellow or purple long-spurred flowers.[2]


Numerous cultivars have been selected for garden use, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:-

  • E. grandiflorum[3]
  • E. grandiflorum 'Nanum'[4]
  • E. grandiflorum 'Rose Queen'[5]
  • E. grandiflorum 'White Queen'[6]

Aphrodisiac properties[edit]

E. grandiflorum may have aphrodisiac characteristics due to the presence of icariin, and is believed to cause increased sexual activity in goats.[7] It is commonly packed in a capsule with other ingredients or sold as herbal flakes or powder with the name "horny goat weed". Further information about the aphrodisiac properties can be found in the main Epimedium article.
