Seedling/Transplant
3-4 weeksSmall plantlets with emerging heart-shaped leaves, typically 2-4 inches tall. Foliage begins showing color variation depending on variety.
Keep soil consistently moist but not soggy. Maintain in shade or dappled light. Harden off gradually before field planting.
Foliage Development
4-8 weeks (spring to early summer)Rosette-forming habit expands with heart-shaped leaves 3-6 inches long. Foliage color intensifies and becomes more saturated; texture may become deeply lobed or ruffled depending on variety.
Ensure consistent moisture and well-draining soil. Mulch lightly around plants to retain moisture. Remove any dead or damaged leaves. Watch for water stress during dry spells.
Flowering
4-6 weeks (late spring to early summer)Tall flower spikes (8-24 inches) emerge from the foliage center, bearing small bell-shaped flowers in shades of red, pink, white, or bicolor. Spikes create vertical interest above the foliage mound.
Continue regular watering. Deadhead spent flowers to encourage longer blooming and tidy appearance. Stake taller varieties if needed in windy locations. Flowers attract hummingbirds and beneficial insects.
Post-Bloom & Fall Color Transition
2-4 months (summer to early winter)Foliage remains vibrant and becomes a primary ornamental feature. Some varieties develop deeper, richer colors in cooler fall temperatures. Flower spikes fade and can be removed.
Cut back spent flower stems at the base. Reduce watering frequency as temperatures cool. Apply winter mulch in cooler zones. Many varieties display the most dramatic foliage color in fall and winter.
Dormancy & Winter
3-4 months (late fall to early spring)In colder zones, foliage may die back partially or completely. In warmer zones and milder winters, evergreen varieties retain leaves with intensified color. Crown remains protected at soil level.
Apply 2-3 inches of mulch around the crown for frost protection in zones 4-6. Do not prune back completely in fall; leave some foliage for insulation. In spring, remove old mulch and dead leaves as new growth emerges.
