Growth Stages
Establishment
4-8 weeksYoung plant develops basal rosette of colorful leaves. Root system establishes and foliage begins to display varietal coloring.
Water regularly to keep soil moist. Mulch lightly around base. Do not cover the crown. Protect from extreme cold in first winter.
Vegetative Growth
8-12 weeksPlant grows outward, forming an expanding mound of colorful foliage. Leaves mature and intensify in color. Plant becomes more robust.
Water during dry spells. Monitor for crown rot in humid conditions. Remove dead or damaged leaves. Foliage color deepens in cool fall temperatures.
Flowering
6-8 weeksDelicate flower spikes emerge from the foliage in spring or early summer. Small bell-shaped flowers in white, pink, coral, or red arranged on thin stems above the leaves.
Deadhead spent flowers to extend blooming period, though seeds attract birds. Provide consistent moisture during flowering. Stake taller varieties if needed.
Summer Dormancy
4-6 weeksPlant may slow growth during hottest months. Foliage color may fade slightly or shift with temperature changes. Some varieties go semi-dormant.
Maintain consistent moisture even if growth slows. Provide afternoon shade in very hot regions. Avoid fertilizing during heat stress.
Fall & Winter
4-6 monthsFoliage becomes more vibrant in cool temperatures, displaying deepest colors. Plant dies back partially or remains semi-evergreen depending on variety and climate.
Reduce watering as growth slows. Leave foliage for winter interest and protection. In harsh climates, mulch lightly for crown protection. Do not cut back until spring.

Harvest Tips
Heuchera is grown for ornamental foliage rather than harvest. Flowers can be cut for fresh arrangements in spring/early summer. Remove spent flower spikes to encourage reblooming. Harvest individual leaves anytime during growing season for arrangements. Cut back dead foliage in early spring when new growth emerges.
