Growth Stages

Seedling

2-3 weeks

Tiny grass-like leaves emerge; seedlings are delicate and require consistent moisture without waterlogging

Keep soil consistently moist but not soggy. Provide bright light. Thin seedlings to proper spacing after 2-3 weeks.

Vegetative Growth

3-4 weeks

Compact mounding plant develops dense, narrow, dark green-gray foliage; reaches 3-6 inches tall

Allow soil to dry between waterings. No fertilizer needed if started in rich soil. Pinch back stems at 2-3 inches to encourage bushiness if desired.

Bud Formation

2-3 weeks

Flower buds form at stem tips; tight clusters of red buds appear against foliage

Continue moderate watering. Can apply balanced fertilizer (10-10-10) every 2-3 weeks to support blooming. Ensure full sun for best bud development.

Flowering

6-10 weeks (or until frost if grown as annual)

Prolific small scarlet-red flowers (petals often have darker centers) open in dense clusters; plant reaches mature height of 10-12 inches

Deadhead spent flowers regularly to encourage continuous blooming. Water deeply but allow soil to dry between waterings. Fertilize every 2-3 weeks for extended flowering.

Decline/End of Season

Variable; until first frost in zones 3-5

Flowering slows as temperatures drop in fall or as plant ages; in cold zones, frost kills annual forms

In zones 5-6, mulch perennial forms lightly in late fall to protect overwinter crowns. In zones 3-4, treat as annual and remove spent plants.
