triangularis, often admired for its purple foliage; white to pale pink flowers colouring, is a bulb variety especially well suited to patio pots.

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

Where to Plant:

Oxalis 'triangularis' (Purpleleaf false shamrock) needs full-sun and a warm, sheltered position for the best flowering. Plant into fertile, humus-rich soil that drains well, and choose a spot protected from strong winds, especially for taller varieties.

How to Plant:

Plant bulb from September to December once conditions are suitable. Set them at the correct depth for the variety, spacing 10–15cm apart where relevant, then firm in gently and water well after planting.

Aftercare:

Water regularly in dry weather and feed every two to three weeks once buds appear. Stake taller stems early and deadhead to keep plants flowering. After flowering, allow foliage to die back naturally before lifting or protecting bulb according to local conditions.

I ordered the mixed hyacinth collection and the scent in my garden this April was absolutely heavenly. Every single bulb produced a strong, beautiful flower and the colours were stunning together. A fantastic purchase, I'll be back for more next year!
