Germination & Seedling
2-3 weeksTiny cotyledons emerge; first true leaves appear oval and small
Keep soil consistently moist but not waterlogged. Provide light exposure. Thin seedlings to proper spacing after true leaves emerge.
Rosette Development
4-8 weeksPlant develops characteristic broad, ribbed leaves in a dense basal rosette; leaves elongate and expand
Maintain moderate moisture. Remove competing weeds. Ensure adequate spacing to allow air circulation.
Leaf Production & Growth
Ongoing, weeks 8+Mature rosette with full-sized leaves (4-12 inches long); plant becomes established and spreading
Harvest outer leaves regularly to encourage new growth. Reduce watering frequency. Plant is very hardy and low-maintenance.
Flowering
4-12 weeks (intermittent)Thin, cylindrical flower spikes (1-4 inches) emerge from the rosette with small greenish or brownish flowers
Allow flowering for seed production if desired, or deadhead to encourage more leaf growth. Flowering occurs spring to fall.
Seed Production & Maturity
3-4 weeks after floweringFlower spikes mature into seed heads containing hundreds of tiny seeds; seeds dry and become ready for dispersal
Allow seed heads to dry on plant if saving seeds. Self-seeds readily; remove flower spikes if you want to prevent spreading.

Harvest Tips
Begin harvesting outer leaves when plant is 4-6 weeks old and has at least 6-8 true leaves. Pinch or cut leaves at the base of the rosette, leaving the growing center intact. Harvest regularly to encourage continued production. Young, tender leaves are most palatable; older leaves become tougher. Can be harvested spring through fall; plant may slow growth in extreme heat or cold.
