Oxalis Autumn Pink

When the rest of the garden starts to wind down, Oxalis ‘Autumn Pink’ steps in with a final flourish of soft pink charm. Also known as Cape Shamrock, this delightful variety produces elegant, trumpet-shaped blooms in a delicate pink hue, streaked with raspberry-pink along the outer petals. Paired with fresh green, clover-like foliage, the flowers are compact but full of character—unfurling in the sun and curling back into perfectly twisted candy shapes each evening.

In the UK, Autumn Pink Sorrel typically blooms from late summer into early winter, offering vibrant colour between August and November. It’s perfect for pots, gravel gardens, rockeries or alpine beds, especially in mild or coastal regions. Give it a sheltered, sunny position and well-drained soil, and you’ll be rewarded with a cheerful show when most of the garden is settling down.

This half-hardy perennial will return reliably year after year in the right conditions, forming a neat clump that slowly multiplies over time. Low maintenance, visually delightful, and blooming when you least expect it—Autumn Pink is a truly rewarding choice for late-season colour.

That said, the Autumn Pink Sorrel isn't fully hardy in the face of heavy frost. As a South African native, it prefers milder winters and can be damaged by prolonged freezing, especially in damp soil.

To keep your cape shamrock bulbs safe:

• In milder UK regions (like coastal or southern areas), you might get away with leaving the bulbs in the ground—just make sure the soil is well-drained and sheltered.

In colder or frost-prone areas, it's best to:

• Grow them in pots or containers you can move to a frost-free spot (like a greenhouse, porch, or bright windowsill).
• Or lift the bulbs after the foliage dies back and store them in a dry, cool, frost-free place (just like dahlias or gladiolus).

These bulbs are small and easy to handle, so if you’re ever unsure, it’s worth the extra step—especially when they reward you with even more blooms next year!
