Keep soil consistently moist but not waterlogged. Protect from heavy foot traffic. Provide bright light.

2

Vegetative Rosette

4-8 weeks

Dense basal rosettes develop with characteristic serrated or deeply lobed leaves radiating from center

Thin seedlings to proper spacing. Remove competing weeds. Maintain moderate moisture.

3

Establishment

4-6 weeks

Mature rosette fully formed with prominent serrated leaf margins; root system deepens

Reduce watering frequency as plant becomes drought-tolerant. Mulch lightly to retain moisture.

4

Flowering

8-12 weeks

Tall, slender flower spikes emerge above foliage with small, inconspicuous flowers; blooms spring to summer

Deadhead spent flowers to encourage more leaf production if harvesting for foliage. Allow some to flower for seed production.

5

Seed Production & Dormancy

4-8 weeks

Seeds mature and ripen; plant enters dormancy in winter in colder zones or remains semi-evergreen in mild climates

Allow seeds to mature for self-sowing or collection. Reduce watering in dormancy. Protect from severe frost in zone 3.
