A low-growing perennial with clover-like foliage and delicate pink flowers that bloom throughout summer. It spreads slowly to form an attractive groundcover in partially shaded areas.

Why grow it

Oxalis debilis offers a fine-textured, low-maintenance groundcover alternative to conventional shade perennials, with the advantage of delicate pink flowers extending through the growing season. Compared to other creeping wood sorrels, it spreads at a moderate pace and tolerates partial shade better than many sun-demanding groundcovers, making it suitable for transitional planting areas or woodland edges.

Watch out for

This species self-seeds readily in favorable conditions, so seedlings may appear in adjacent beds or containers if moisture remains consistent through late season. In containers or densely planted settings, monitor for powdery mildew during humid periods, as crowded foliage can limit air circulation.
