📏
Spacing: 12 inches
📅
Days to maturity: Plants reach full size in 2-3 years; flowering begins in year 1
🌱
Planting depth: Plant at soil level; crown should be at or slightly above soil surface (do not bury)

Growth Stages

1

Establishment

4-8 weeks

Small rosette of coral-red leaves emerging from root system; compact growth habit visible

Keep soil consistently moist. Apply mulch around (not over) crown. Monitor for transplant shock and protect from strong winds.

2

Vegetative Growth

Spring through early summer

Foliage expands into a dense, mounding rosette with deepening coral-red coloration; leaf texture becomes more pronounced

Maintain moisture during dry spells. Fertilize monthly with balanced, dilute fertilizer. Color intensifies as temperatures cool.

3

Flowering

Late May through July (4-6 weeks)

Delicate, small pink to coral flowers appear on tall, wiry stems rising above the foliage; flowers arranged in airy panicles

Deadhead spent flowers to encourage continued blooming and maintain plant appearance. Support tall flower stems if necessary in windy locations.

4

Post-Flowering & Summer Color

July through October

Flowers fade; foliage becomes the main display; leaf color may deepen further with summer heat, then brighten in fall

Remove dried flower stems. Continue regular watering. In zones 8+, provide afternoon shade to prevent foliage bleaching in intense heat.

5

Dormancy & Winter Interest

November through March

Foliage persists, often darkening to rich burgundy or deep red; evergreen to semi-evergreen depending on zone

Reduce watering but do not let soil dry completely. Do not remove old foliage—it provides winter protection and visual interest. Remove debris around crown to prevent rot.

Companion Planting

Plan your garden →

Plant with:

Coral Bells (other Heuchera varieties) Sedums and other succulents Ferns (Dryopteris, Polystichum) Carex (ornamental sedges) Astilbe Hellebores Epimedium Tiarella Foamflower Japanese Forest Grass (Hakonechloa)

Avoid planting near:

Water-loving plants that prefer consistently wet soil (may lead to crown rot) Aggressive, spreading perennials that compete for space (e.g., some mints, tall ornamental grasses)

Common Pests

  • Inspect foliage regularly for notched leaf margins. Remove by hand or use insecticidal soap. Diatomaceous earth applied to soil surface can reduce larval populations.

  • Remove affected leaves promptly to reduce populations. Maintain plant vigor through proper watering and fertilizing. Spinosad spray if infestations are severe.

  • Increase humidity around plants. Spray foliage with water to dislodge mites. Insecticidal soap or neem oil if populations become problematic.

  • Ensure excellent drainage and avoid waterlogging. Do not mulch over crown. Remove affected plants and improve soil drainage before replanting.

Harvest Tips

Wickwar Flame is not harvested for food or medicinal uses; it is grown purely as an ornamental. Cut flowers are not typically used in arrangements. Remove spent flower stems as desired for aesthetic purposes.

Fun Facts

  • 🌱 Wickwar Flame's coral-red foliage becomes even more intensely colored when exposed to cooler autumn temperatures, a phenomenon called anthocyanin production that acts as a natural 'sunscreen' in cold weather.
  • 🌱 Heuchera 'Wickwar Flame' is a cultivar created through horticultural breeding; it represents decades of selective plant breeding to enhance foliage color and garden performance.
  • 🌱 Unlike many shade plants, Wickwar Flame can tolerate considerable sunlight (up to 6 hours daily), and the full color display is actually enhanced by moderate light exposure.
