Common Sorrel

Oxalis stricta

herb

Oxalis stricta is a small herbaceous plant with clover-like trifoliate leaves and delicate yellow flowers. It's a prolific self-seeding plant found worldwide, often considered a weed but valued in some cuisines for its lemony, sour flavor. The plant produces small seed pods that explosively disperse seeds when ripe.

Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with first true leaves appearing within 7-14 days

Keep soil moist and provide bright indirect light. Avoid burying seeds.

2

Seedling

2-3 weeks

Small plants develop characteristic trifoliate (three-lobed) leaves and establish a shallow root system

Thin seedlings to proper spacing. Water regularly but allow soil surface to dry between waterings.

3

Vegetative Growth

3-4 weeks

Plant grows bushy with increasing leaf production; leaves become harvestable

Pinch back growing tips to encourage bushier growth. Remove any flowering stems if maximizing leaf production is desired.

4

Flowering

Continuous from week 4 onward

Delicate pale to bright yellow flowers with five petals appear throughout the growing season

Allow some flowers to set seed for self-perpetuation, or deadhead to extend leaf production. Flowers are edible.

5

Seed Production & Dispersal

4-6 weeks per seed cycle

Small elongated seed pods develop and mature; pods explosively burst when dry, scattering seeds

If preventing self-seeding, harvest pods before they dry and split. Otherwise, allow seeds to drop for continuous volunteer plants.

Uses

Salads and fresh greens

Culinary

Young leaves and stems add a bright, lemony tartness to salads, sandwiches, and garnishes. The leaves are tender and refreshing with a pleasant oxalic tang. [source]

🍳

Beverages and infusions

Culinary

Fresh leaves can be steeped into herbal tea for a citrusy drink, or added to smoothies and cold beverages for tart flavor. [source]

💊

Traditional remedy

Medicinal

Historically used in folk medicine to support digestion and reduce fever, though consumption should be moderate due to oxalic acid content. [source]

🏠

Natural cleaner

Household

The oxalic acid in the plant can be used to make a natural cleaning solution for removing stains and rust from surfaces. [source]

🦋

Pollinator support

Wildlife

Yellow flowers attract bees, butterflies, and other beneficial insects; seed production provides food for birds and small creatures. [source]

Harvest Tips

Harvest leaves and stems when plant is 4-6 inches tall; pinch off outer leaves and stem tips to encourage branching. Harvest regularly to prevent flowering and promote continued leaf production. Flowers and seed pods are also edible. Can be harvested continuously from spring through fall in most zones.

Fun Facts

  • 🌱 Oxalis stricta produces explosive seed pods that catapult seeds up to 9 feet away when ripe and disturbed, allowing the plant to colonize new areas rapidly.
  • 🌱 The plant's name comes from the Greek word 'oxys' meaning 'sharp' or 'sour,' referring to the tangy taste from oxalic acid in the leaves.
  • 🌱 Despite being considered a nuisance weed in gardens worldwide, Oxalis stricta is cultivated intentionally in some regions (particularly in parts of Asia, Africa, and South America) as a nutritious leafy green.
