Northern Exposure Black Coral Bells

Northern Exposure Black Coral Bells (Heuchera x richardsonii 'TNHEUNB')

Northern Exposure Black Coral Bells is a hardy foliage perennial that brings deep color, strong texture, and reliable landscape performance to beds, borders, and containers through a long season. Its rounded dark leaves create bold contrast against chartreuse, silver, green, and flowering companions, helping mixed plantings feel more grounded and more intentional. Because it forms a dense, medium-sized mound, it works especially well where the planting needs more presence than many smaller coral bells can provide. This variety is a strong choice for gardeners who want bold foliage color, broad hardiness, and a perennial that holds its look well from spring through fall.

The cleaner, rounded foliage gives it a polished appearance that works in both formal and naturalistic designs. Its improved rust resistance and longer-lasting seasonal appearance also make it especially practical for repeated use in borders, mass plantings, and larger mixed containers. Light flowers add a softer accent above the foliage, but the leaves remain the main attraction throughout the growing season. For plantings that need contrast, structure, and dependable garden value, this selection offers broad landscape usefulness.

Distinctive Features

Northern Exposure Black Coral Bells forms a dense mound of rounded, slightly ruffled foliage in smoky chocolate-black to deep purple-black tones, often showing garnet to burgundy undersides and occasional silvery highlights. The foliage mound typically reaches about 10 inches tall and about 23 to 28 inches wide, giving it more spread and landscape presence than many compact coral bells. Short flower stems rise above the foliage with small white to pale pink flowers from late spring into early summer. Its hardy richardsonii background, dark rounded leaves, excellent rust resistance, and strong longevity make it especially useful where dependable foliage performance matters as much as color.

Growing Conditions

• Sun: Full sun to full shade is tolerated, though part shade is often best in many garden settings and helps preserve foliage quality in hotter regions.
• Soil: Moderately well-drained, organic soil is best, though it can adapt to average garden soil if drainage is reliable.
• Water: Average moisture is ideal, with established plants generally performing better on the slightly drier side rather than in overly wet soil.
• Zones: USDA Zones 3 to 9 are the most consistently supported range for reliable performance.
• Habit: This plant grows in a dense, medium-sized, clumping, mounded form with short flower stems rising just above the foliage.

Ideal Uses

• Focal Point: Its rounded black foliage makes it an excellent focal point in small shade gardens, mixed borders, and decorative containers.
• Mass Planting: Planted in groups, it creates a broad sweep of dark foliage color that adds depth and unity to the landscape.
• Borders: It works beautifully along the front or middle of perennial borders where the dense mound can anchor brighter companions.
• Containers: The full habit and dark foliage make it a strong choice for patio pots, entry planters, and mixed seasonal containers.
• Mixed Beds: It blends well into mixed perennial beds where long-lasting dark foliage helps hold the planting together through the season.

Low Maintenance Care

• Watering: Water regularly during the first growing season, then provide supplemental moisture during extended dry weather as needed.
• Cleanup: Trim back ragged foliage in early spring to freshen the plant and make room for clean new growth.
• Drainage: Avoid overly wet soil, especially in winter, because soggy conditions around the crown can reduce vigor and longevity.
• Planting Depth: Keep the crown at the proper level and do not bury it when planting.
• Disease Resistance: This variety is noted for strong rust resistance, which supports a cleaner appearance over a longer season.
