Seedling
2-3 weeksSmall cotyledons emerge with delicate true leaves developing. Plant is fragile and low-growing.
Keep soil consistently moist. Avoid direct strong sunlight. Thin seedlings to 12 inches apart once they have 2-3 true leaves.
Vegetative
3-4 weeksLeafy rosette forms with deeply lobed, pinnate green leaves. Plant develops a low spreading mound.
Maintain consistent moisture and partial shade. Remove any dead or diseased leaves. Begin harvesting outer leaves once plant has 6+ leaves.
Flowering
3-4 weeksSmall clusters of white, four-petaled flowers appear on branching stems above the foliage. Typically occurs in spring or early summer.
Flowers are edible and add visual interest. Allow some flowers to remain for seed production if desired. Continue regular watering.
Seeding
2-3 weeksSmall silique pods develop from spent flowers, containing seeds for propagation.
Allow pods to mature and dry on the plant if seed collection is desired. Plant self-seeds readily in favorable conditions.

Harvest Tips
Harvest young leaves regularly once plant has 6+ leaves, typically 4-6 weeks after planting. Cut outer leaves at the base to encourage continued growth, or harvest entire plant by cutting 1-2 inches above soil level for regrowth. Best harvested in morning after dew dries. Leaves become more peppery as they mature. Can continue harvesting throughout the growing season; before flowering produces milder, more tender leaves.
