Seedling
3-4 weeksTiny plants with 2-4 small oval leaves, very fine-textured foliage
Keep soil barely moist; provide bright light and excellent drainage. Avoid overwatering, which causes damping off.
Vegetative Growth
4-8 weeksCompact mounding growth with narrow, aromatic gray-green leaves developing a rounded outline
Water moderately as plant establishes. Pinch tips early to encourage bushier growth. Mulch lightly to conserve moisture.
Flowering
4-5 months (spring through frost in warm climates)Abundant spikes of bright red tubular flowers held above the foliage; plant reaches mature compact size of 18-24 inches tall and wide
Deadhead spent flowers to encourage continuous blooming. Reduce water frequency; drought actually promotes flowering. Little supplemental fertilizer needed.
Peak Production
2-3 months (summer peak)Dense flowering shrub completely covered with red flower spikes, attracting hummingbirds and butterflies constantly
Continue deadheading for maximum blooms. Ensure excellent drainage. Minimal pest/disease issues. Reduce water further during peak season.
Decline & Winter
Variable by climateFlowering slows in extreme heat or cold; foliage remains attractive even when not in bloom
In zone 8, provide light mulch protection. In zones 9-10, may flower year-round. Prune in early spring to remove dead wood and shape plant.
