Oxalis montana, commonly referred to as Sourgrass, is a perennial flowering plant belonging to the wood sorrel family. Typically, it thrives in clusters within cool, nutrient-rich, and moist woodlands, particularly in hemlock and spruce-fir forests. Its attractive low-growing form, adorned with white or pink blossoms, makes it a popular choice for flower gardens, lawns, and even as a houseplant. However, it can become invasive in disturbed environments.
This plant features a mound-like growth habit with clover-shaped leaves and produces multiple flowers, each on its own stalk. Sourgrass favors moist soil and partial shade for optimal growth. It spreads indefinitely through runners, either via rhizomes or stolons, and its extensive root system plays a crucial role in soil stabilization. The leaves exhibit a unique behavior, opening and closing in response to sunlight, while the flower colors vary from white to pink, influenced by elevation. At lower altitudes, the petals display more pronounced pink-purple veining. In addition to its vibrant blooms, Sourgrass also produces cleistogamous flowers, which remain closed to facilitate self-pollination. This plant is considered to have low toxicity, making it safe for consumption in small quantities by both humans and animals.
