Oxalis triangularis

Oxalis triangularis, commonly known as purple shamrock, is a clump-forming perennial with striking triangular, deep purple leaves that open in daylight and fold at night. In late spring to summer, it produces delicate, funnel-shaped pale pink to white flowers, creating a charming and decorative display in containers, borders, or rockeries.

The flowers attract bees and other pollinators, giving the plant ecological value. Its compact, moisture-loving habit makes it ideal for pots, damp borders, or naturalistic plantings where bold foliage and seasonal flowers are desired.
