Epimedium grandiflorum, commonly known as Bishop’s Hat, is a perennial herb that can be deciduous or semi-deciduous depending on the climate. It is native to the forest floors and shaded rocky areas of Japan, where it thrives under the canopy of larger trees. This plant typically grows to about 30 cm (12 inches) in height and features bright red stems with green, heart-shaped leaves that are copper-tinged when young and become slightly hairy underneath as they mature. In the spring, Bishop’s Hat produces an array of long-spurred flowers in shades of pink, white, yellow, or purple, which are quite showy and add a delicate charm to garden spaces.

Bishop’s Hat is valued for its attractive foliage and flowers, which can brighten up shaded areas of the garden. It is often used as a ground cover or in border plantings, particularly in woodland gardens or shaded rock gardens. This plant is relatively low-maintenance, requiring minimal care once established. It prefers part shade to full shade and can tolerate a range of soil drainage conditions, from slow to fast. While it does best with consistent moisture, it can withstand periods of drought once established. Gardeners should be aware that Epimedium grandiflorum can be susceptible to vine weevil damage and may require monitoring and control measures.CC BY-SA 4.0
