The Story
Plant Bio
Oxalis stricta, common yellow woodsorrel, is a low spreading perennial native to both North America and Eurasia, reaching two to twelve inches. Clover-like leaves of three heart-shaped leaflets fold shut at night and in bright sun. Small five-petalled yellow flowers appear from spring through autumn, followed by upright cylindrical seed capsules held above the foliage.
Those capsules are the reason it is so hard to be rid of: when ripe they split explosively and can fling seed up to sixteen feet, well beyond wherever you were weeding. The whole plant is edible with a sharp lemony taste from oxalic acid, which is also the reason to eat it only in small quantities.

Planting
How to Grow
- It arrives on its own; deliberate planting is rare.
- It accepts full sun to partial shade and poor soil.
- Nothing needs watering or feeding for it to thrive.
- Remove seed capsules before they ripen to limit spread.
- Hand-weed while plants are small and roots shallow.
- Mulch bare soil, since seed needs light and open ground.
Pro Tip
Weed it before the seed capsules stand upright — once they are ripe, disturbing the plant fires seed several feet in every direction.

Care Guide
Do
- Hand-weed while plants are still small 🌱
- Remove capsules before they ripen ✂️
- Mulch bare soil to deny it germination sites 🍂
- Use leaves sparingly as a sharp salad herb 🍋
Don't
- Pull it once the capsules are ripe; that scatters the seed ❌
- Eat it in quantity, because of the oxalic acid ❌
- Leave bare soil, where it germinates fastest ❌
