Red Barrenwort

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.

Growing Conditions

• Sun Exposure: Partial to full shade; morning sun acceptable with steady moisture.
• Soil: Humus-rich, well-drained loam; benefits from added compost or leaf mold.
• Water: Moderate; keep evenly moist the first season, then water deeply during prolonged dry spells.
• USDA Hardiness Zones: 5 to 8.
• Mature Size: About 8 to 12 inches tall in leaf, 12 to 18 inches in bloom, spreading 18 to 24 inches over time.

Ideal Uses

• Woodland Gardens: Jewel-toned flowers and layered foliage brighten shaded beds.
• Understory and Dry Shade: Reliable beneath trees and around established roots.
• Edging and Paths: Compact clumps create a tidy, fine-textured border.
• Groundcover Massing: Plant in drifts for a durable, living mulch.
• Mixed Shade Borders: Pairs beautifully with hellebores, ferns, hostas, and heucheras.

Low Maintenance Care

• Cutback: Shear old foliage in late winter before buds rise to showcase spring bloom.
• Mulching: Apply 2 to 3 inches of compost or leaf mold to conserve moisture and enrich soil.
• 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.
• Watering: After establishment, occasional deep watering in extended drought is sufficient.

Why Choose Red Barrenwort?

• Warm Spring Color: Spurred red-rose flowers create a luminous, floating display.
• Seasonal Foliage Interest: Bronze spring flush and warm fall tints add multi-season color.
• Shade Problem Solver: Thrives in dry, root-filled sites where many perennials fail.
