Oxalis stricta, commonly known as common yellow woodsorrel, is a perennial herb native to a variety of habitats including open woodlands, fields, grasslands, and disturbed areas across North America and parts of Eurasia. It typically grows to a height of 4-16 inches (10-40 cm) and spreads to form a loose cluster. The plant features compound leaves, each divided into three heart-shaped leaflets that fold downward in the evening or in response to touch, and it produces small, cup-shaped yellow flowers from late spring through early fall, which are particularly showy when in large numbers.

Common yellow woodsorrel is appreciated for its delicate appearance and the bright splash of color it adds to garden spaces. It is often found in informal garden areas, rock gardens, and as a filler in borders or between stepping stones. This plant prefers well-drained soil, tolerates a range of soil types, and can grow in full sun to partial shade. It is drought-tolerant once established and requires minimal maintenance. However, gardeners should be cautious as it can become weedy due to its prolific seed production and ability to regenerate from root fragments.CC BY-SA 4.0
