Growth Stages

1

Seed Germination

2-4 weeks

Seeds are tiny and require light to germinate; they develop a small rosette of hairy leaves.

Surface sow on moist, gritty soil. Provide cool stratification (4-6 weeks cold period). Keep soil moist but not waterlogged. Germination is slow and irregular, taking 2-4 weeks.

2

Seedling & Rosette Development

3-6 months

Small rosettes of hairy, textured leaves emerge and gradually expand. Plant remains compact and low-growing.

Maintain gritty, well-draining soil. Provide bright light but avoid direct afternoon heat. Water carefully to avoid damping off. Handle delicate seedlings with care.

3

Vegetative Growth

6-12 months

The rosette enlarges with more hairy leaves developing. The plant forms a tight, dense mound, typically 2-4 inches tall.

Ensure excellent drainage around the plant. Apply gravel or grit mulch to prevent moisture accumulation around leaves. Protect from excessive humidity and wet conditions.

4

Flowering

4-8 weeks

Small flower stalks emerge from the rosette center, bearing delicate pink to magenta flowers with reddish, hairy calyces. Flowers typically appear in late spring to early summer.

Maintain consistent moisture during flowering without waterlogging. Deadhead spent flowers to encourage continued blooming. Provide cool conditions and good air circulation.

5

Seed Set & Dormancy

8-10 weeks

After flowering, the plant produces small seed capsules. As temperatures drop in fall, foliage may die back partially or fully depending on zone.

Allow seeds to mature if collecting. Reduce watering as plant enters dormancy. Provide winter protection in colder zones with a gritty, well-draining mulch layer to prevent frost heave.

Common Pests

  • and

    Remove by hand in early morning; use gritty mulch barriers; apply copper tape around containers; maintain dry conditions around foliage

  • Ensure excellent air circulation; avoid wetting foliage; remove affected leaves immediately; reduce humidity; improve drainage

  • Increase humidity with misting (without wetting foliage excessively); use insecticidal soap; ensure good air circulation

  • Prevent with fast-draining soil and gravel mulch; do not overwater; repot in fresh gritty soil if infection occurs
