Heuchera 'Blackout' Coral Bells

Heuchera 'Blackout' Coral Bells is a compact, evergreen perennial popular for its deep, nearly black foliage and pollinator-friendly flowers. Reaching a mature height of 8 to 12 inches and spreading 16 inches wide, 'Blackout' adds interest across three seasons, and even year-round in warmer climates. Its dense, basal rosette of glossy, near-black leaves is slightly waved and held horizontally on dark purple petioles, creating a stunning display. In midsummer, slender 10-inch scapes rise above the foliage, showcasing clusters of bell-shaped, creamy white flowers that attract bees, butterflies, and hummingbirds. These long-lasting blooms also make elegant additions to floral arrangements.

This Heuchera hybrid, commonly known as coral bells or alumroot, features a low, mounding habit and grows more vigorously than many other dark-foliaged varieties. 'Blackout' performs beautifully in containers, garden beds, and borders. It is especially eye-catching when massed or grouped, where its rich color creates striking contrasts, and it also serves as a lovely edging plant along paths or walkways. Consider pairing it with complementary shade-tolerant plants like ferns, astilbe, geranium, hakonechloa, and hosta for a dynamic garden display.

Easy to grow and virtually carefree, 'Blackout' coral bells thrive in sunny to partially shady areas with well-draining, medium moist soil. It tolerates a neutral to slightly acidic pH but adapts well to most soils. While moderately drought-tolerant once established, it benefits from consistent moisture, particularly in full sun or hot climates where afternoon shade may help protect its foliage. For best results, fertilize and remove dead leaves in spring and mulch in late fall to maintain soil temperature and prevent frost heaving. Naturally deer resistant, 'Blackout' is an excellent choice for low-maintenance landscaping with unique coloration.
