Establishment
4-6 weeksSmall transplant with emerging deep purple-tinged leaves; plant is adjusting to garden conditions
Water regularly to keep soil moist. Avoid transplanting in extreme heat. Apply mulch around base but not touching crown to prevent rot.
Vegetative Growth
Spring through early summerFoliage expands with increasingly darker purple coloration; leaves become more lobed and ornamental; plant spreads outward
Maintain consistent moisture. Deadhead flower spikes if desired to focus energy on foliage. Remove any reverted green-leaved shoots immediately.
Flowering
Late May through JulyTall, delicate flower spikes emerge above the foliage bearing tiny flowers in white, pale pink, or coral depending on variety
Flowers are secondary to foliage appeal. Deadhead to encourage longer plant life and prevent excessive self-seeding. Spikes may be left for structure.
Summer Maturity
July through SeptemberPlant reaches full size with dense mounding habit; foliage color remains vibrant and deep purple
Water during drought. Monitor for spider mites in dry conditions. Remove any diseased or damaged leaves. Divide congested plants if needed.
Fall & Winter Dormancy
October through MarchFoliage persists and often deepens in color; growth slows significantly. Plant remains evergreen to semi-evergreen depending on zone
Reduce watering as temperatures cool. Do not cut back foliage; it provides winter interest and protection. Clean up dead leaves only in spring.

Fun Facts
- 🌱 The common name 'coral bells' refers to the delicate coral, pink, or white flower spikes, though dark purple heuchera varieties often produce white or pale flowers that contrast beautifully with the dark foliage.
- 🌱 Dark purple foliage color intensifies with more shade—paradoxically, the darkest purple varieties develop richer pigmentation when grown in partial to full shade rather than sun.
- 🌱 Heuchera naturally hybridizes readily, creating hundreds of cultivars; many modern dark purple varieties are crosses between multiple species, selected for intense foliage color and vigor.
