Growth Stages

1

Germination & Seedling

2-3 weeks

Tiny seedlings with cotyledons emerge; small compound leaves develop slowly

Keep soil slightly moist but not wet. Ensure good light. Thin seedlings to proper spacing. Avoid transplanting if possible.

2

Vegetative Growth

3-6 weeks

Plant develops rosette of blue-green, narrow linear to lanceolate leaves; compact growth habit

Water minimally; allow soil to dry between waterings. No fertilizer needed in poor soil. Ensure excellent drainage.

3

Flowering

4-8 weeks

Golden-yellow, four-petaled flowers emerge on branching inflorescences; fragrant blooms attract pollinators

Deadhead spent flowers to encourage continued blooming. Reduce watering further. No supplemental feeding required.

4

Seed Pod Development

3-4 weeks

Distinctive curved, sickle-shaped siliques (seed pods) form; very ornamental feature characteristic of the species

Allow pods to mature on plant. Reduce or cease watering. Allow pods to dry for seed collection.

5

Seed Maturity & Dormancy

Ongoing

Pods turn brown and dry; seeds mature inside pods and are ready for collection

Collect seed pods before they shatter. Store seeds in cool, dry conditions for future sowing.
