Seedling & Establishment
3-4 weeksHeart-shaped leaflets develop and expand. Small rosette forms close to ground. Root system establishing.
Maintain consistent moisture. Protect from slugs and direct sun. Avoid overwatering to prevent damping off.
Vegetative Growth
4-8 weeksPlant produces multiple leaf stems with characteristic three-lobed heart-shaped leaflets. Dense ground cover developing.
Begin light harvesting of outer leaves. Keep moist. Mulch around plants to retain moisture. Remove any damaged leaves.
Flowering
4-6 weeks (spring/early summer)Delicate white, pink, or pale purple flowers appear above foliage on thin stems. Flowers have five petals.
Continue regular watering. Flowers attract pollinators. Can be harvested for visual appeal in salads.
Seed Production & Dormancy
Variable; dormancy 4-6 months in winter zonesSeed pods develop after flowering. Plant may go dormant in hot summers or late fall depending on zone.
Allow some flowers to set seed for self-seeding. Cut back dead foliage in fall. Mulch in winter for frost protection in colder zones.

Harvest Tips
Begin harvesting leaves 30-45 days after planting when plant is established. Pinch off outer leaves regularly to encourage bushiness and continued production. Harvest in morning for best flavor. Can be harvested year-round in milder zones, though production slows in winter. Best flavor before flowers bloom. For seeds, allow flowers to mature and collect seed pods when dry.
Fun Facts
- 🌱 Wood sorrel leaves fold up at night in a process called nyctinasty, a daily sleep-like movement that protects the plant from dew and predators.
- 🌱 The plant's common name 'sorrel' comes from the Old French 'surelle,' and it has been foraged and cultivated in Europe for over 1,000 years.
- 🌱 Wood sorrel produces seed pods that explosively dehisce, flinging seeds several feet away to colonize new areas—a mechanism plants use to spread beyond the parent plant.
