Coral bells (Huechera family) ‘Firefly’ is a winner in Colorado shade gardens
Coral Bells is the ultimate versatile and colorful perennial for shady areas of the garden in our area. They sport multi-season interest and a long bloom time (especially the ‘Firefly’ variety).
Firefly’ has a compact habit and deep green leaves and produces a profusion airy spikes of red-fading-to-pink bell-shaped flowers on wiry stems (great as a cut flower in a bouquet). Flower spikes are 12-18 inches tall.
Looks great in borders, containers, shade gardens, under trees, and in mixed perennial beds.
Light Preferences
- Best: Partial shade to dappled shade.
- Tolerance: Performs in full shade (color may fade) or morning sun/afternoon shade. Protect from strong afternoon sun to avoid leaf scorch.
Soil & Water
- Well-drained, humus-rich soil; prefers slightly acidic to neutral pH.
- Moisture: Consistent but moderate moisture. Do not overwater or waterlog. Mulch around plant to conserve moisture but keep away from crown.
Feeding
- Fertilizer: Light application of balanced slow-release fertilizer in spring or a top-dressing of compost; avoid heavy nitrogen which can reduce leaf color intensity.
Temperature & Hardiness
- Hardiness: Firefly is hardy to USDA Zone 4 and typically tolerates cool winters.
- Mulch in Fall to protect crowns; remove mulch in early spring to prevent rot.
Maintenance
- Pruning: Remove dead and damaged leaves throughout the season; trim flower stalks after they bloom to keep the plant tidy and encourage fresh foliage.
- Coral bells benefit from dividing every three to six years in early Fall to rejuvenate clumps and control spread.
- Pests and Diseases: Coral Bells are generally a nicely low-maintenance perennial. Watch for crown rot in poorly drained soil, vine weevils (the larvae eat roots), and powdery mildew in crowded conditions.
- Propagation: By division in Spring/Fall.
