The first of the two species I have shown below is Epimedium x rubrum, which is commonly known as Bishop's Mitre (or Hat) from the shape of the flowers, or red barrenwort. The second, shown below Bishops Mitre, is Epimedium grandiflorum which is also known by several other names: Longspur Epimedium, Barrenwort 'Orangekonigin' or Horny Goat Weed (Wikipedia will tell you why it's known as Horny Goat Weed) to name a few. Both of these plants are low growing and spread somewhat slowly... both require cutting back in February before the new growth starts and both bloom profusely in spring before the weather gets too hot. Filtered sunlight is fine early in the growing season but full shade is best during the heat of summer which makes them perfect under my dogwood trees in the front garden!
