Red Barrenwort (Epimedium x rubrum)
Red Barrenwort (Epimedium x rubrum) is a classic shade perennial valued for nodding sprays of red to rose flowers in mid to late spring and elegant, heart-shaped foliage that shifts color through the seasons. New leaves emerge bronze to copper, mature deep green for summer, and often warm to red tones in fall. Slowly forming a refined, drought-tolerant clump, it excels under trees, along shaded paths, and in woodland borders where subtle bloom and reliable texture are prized.
Distinctive Features
Abundant, long-spurred red-rose flowers carried on wiry stems above the foliage; fresh spring growth flushed bronze for added color; semi-evergreen in mild climates; naturally deer and rabbit resistant; excellent tolerance of dry, rooty shade once established.

- Feeding: Light spring top-dress with compost or a balanced slow-release fertilizer.
- Division: Divide clumps in spring or early fall to refresh vigor or extend plantings.
