Germination
1-2 weeksTiny seedlings emerge with cotyledons visible. Early leaf development begins.
Keep soil consistently moist but not waterlogged. Provide adequate light. Thin seedlings to proper spacing.
Rosette Development
3-6 weeksYoung plant develops characteristic basal rosette of oval leaves with prominent parallel veining. Leaves remain low to ground.
Maintain moderate moisture. Allow plant to develop 6-8 leaves before first harvesting. Remove weeds around rosette.
Established Plant
Ongoing through growing seasonFull rosette formation with mature oval leaves reaching 2-4 inches long. Plant spreads outward from central crown.
Drought-tolerant at this stage. Harvest outer leaves regularly to encourage new growth. Remove flower spikes if leaf production is priority.
Flowering
4-6 weeks in summerTall, slender flower spikes emerge from center of rosette. Spike contains tiny greenish flowers arranged densely along stem.
Allow some flowering for seed production or cut spikes to encourage continued leaf harvesting. Spikes are less palatable than leaves.
Seed Production
4-8 weeks after floweringFlowers develop into seed capsules containing tiny seeds. Spikes dry and turn brown.
Allow to dry in place for self-seeding or collect seed spikes for storage. Seeds remain viable for 3+ years.

Harvest Tips
Begin harvesting outer leaves when plant has 6-8 leaves, typically 8-12 weeks after planting. Pinch or cut leaves at base of petiole. Harvest regularly to prevent flowering and encourage more tender growth. Young leaves (pre-flowering) are most tender. Best harvested in spring and early summer. Can harvest continuously through growing season; perennial plants produce for 3-5+ years.
