Oxalis 'triangularis' (Purple Leaf false shamrock)
Oxalis triangularis is a small treasure for pots and sheltered corners, prized for its distinctive, clover-like foliage in sumptuous purple. Through summer it lifts itself with dainty, funnel-shaped flowers in soft white to the palest blush—an effortlessly elegant pairing against the dark leaves. Ideal for patio containers, rock gardens and an alpine house, it forms neat clumps and settles in quickly, bringing a refined note wherever you place it. Best in a sunny, sheltered position with well-drained compost or soil. Foliage first: rich purple, triangular leaves for season-long interest Summer flowering: June to September blooms in white to pale pink Perfect in pots: a charming choice for containers, alpine settings and sheltered borders
