Growth Stages

1

Seedling

2-3 weeks

Tiny seedlings with cotyledons emerge within 10-14 days. First true leaves are finely divided and feathery.

Keep soil consistently moist but not waterlogged. Provide bright light. Thin seedlings to 12 inches apart when large enough to handle.

2

Vegetative Growth

4-8 weeks

Plant develops increasingly fine, fern-like foliage in a mounding habit, 12-18 inches tall. Leaves are blue-green and delicately compound.

Water regularly during establishment. Pinch tips occasionally to encourage bushier growth. Remove any flower buds if harvesting leaves is the priority.

3

Flowering

6-10 weeks

Distinctive round flower heads (pompom-like) appear on tall stems above foliage. Flowers start green and deepen to burgundy-red as they mature.

Continue regular watering. Flowers attract pollinators and are edible. Leave some flowers for seed production if desired.

4

Seed Development & Maturation

4-6 weeks

Spent flowers develop into small seeds. Foliage may become tougher and less tender as the plant matures seasonally.

Allow plants to dry out slightly more. If saving seeds, leave flower heads on plant until fully dry. Cut back to encourage new tender growth.

5

Dormancy (Winter)

3-4 months

In colder zones, foliage dies back to the ground; the plant survives as a dormant root system. In mild climates, some foliage may persist.

Reduce watering significantly. No fertilizing needed. Mulch in zones 3-5 for extra winter protection. Remove dead growth in spring.

Harvest Tips

Begin harvesting leaves once plant is 6-8 inches tall, typically 4-6 weeks after germination. Pinch off outer leaves regularly to encourage new growth. Harvest before flowering for most tender foliage, or harvest flowers fresh for color and mild flavor. Cut stems near the base for more aggressive harvesting; the plant will regenerate. Best harvested in cool morning hours for maximum flavor.
