Red Barrenwort, Epimedium alpinum 'Rubrum', Bishop's Hat 'Rubrum', Bishop's Mitre 'Rubrum', Fairy Wings 'Rubrum'
One of the best Epimediums available, Epimedium × rubrum (Red Barrenwort) is a deciduous, rhizomatous perennial with attractive, heart-shaped, pointed leaves that emerge red-flushed in spring, mature to shiny green and turn red in fall. In mid to late spring, clouds of small, dainty flowers, 1 in. across (2 cm), hover on the ends of wiry stems just above the foliage. Slightly spurred, their large rosy-red sepals cover snowy-white petals and contrast nicely with the creamy-yellow stamens. A tough and durable groundcover or edger for shady garden spots.
- Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society.
- Grows up to 15 in. tall (37 cm) and 24 in. wide (60 cm). Rhizomatous perennial which spreads faster than most other epimediums.
- Performs best in part shade to full shade in average, dry to medium moisture, well-drained soils. Humus-rich, fertile, moist soils in part shade are preferred. Drought tolerant once established. Protect from cold, dry winds.
- No serious pest and disease problems. Watch for vine weevils. Rabbit and deer tolerant.
- Easy to grow, this plant is a welcomed addition to beds and borders, rock gardens, shade gardens. Excellent as a groundcover.
- Propagate by division in fall or after flowering.
- Cut back old foliage in late winter or early spring for the best display of new foliage and flowers.
