Growth Stages

1

Seed Germination

2-4 weeks

Tiny seeds germinate on moist moss surface; first threadlike leaves emerge

Keep at 65-75°F; maintain high humidity; provide bright, indirect light; don't bury seeds

2

Seedling/Juvenile Rosette

4-8 weeks

Small rosette forms with sticky leaves; plant remains tiny, 0.5-1 inch diameter

Maintain consistent moisture and humidity; keep away from direct sun; monitor for mold due to high moisture

3

Mature Rosette

8-12 weeks

Rosette expands to 1-3 inches diameter with full complement of sticky, glandular leaves; ready to flower

Increase light gradually; ensure good air circulation; some species enter winter dormancy at this stage

4

Flowering

4-8 weeks

Delicate flower stalks emerge from rosette center; blooms in purple, pink, white, or yellow; flowers are attractive to pollinators

Continue regular watering; maintain humidity; avoid moving plants during blooming; flowers last 1-2 weeks

5

Fruiting & Seed Production

4-6 weeks

Flowers fade and develop seed capsules; plant may set hundreds of tiny seeds

Allow seeds to mature and dry; collect seeds when capsules turn brown; plants may rest afterward
