Oxalis triangularis (Purple shamrock)
£6.69
Unit price perEstimated Delivery between January 10 and January 12.
Oxalis triangularis is loved for its dramatic purple foliage and delicate white flowers above deep purple leaves, bringing a jewel-toned feel to pots, hanging baskets, and sunny windowsills. It’s a brilliant way to add colour and texture with minimal fuss.
Growing to around 20–30 cm, oxalis forms compact clumps and can flower repeatedly through the warmer months. The leaves open and close with the light, adding extra movement and interest to displays.
Grow in well-drained compost or soil, in a sheltered spot with bright light. It can be grown outdoors in summer and moved under cover before frosts, or kept as an easy houseplant year-round.
Water when the top of the compost dries out and feed lightly during active growth. Oxalis may go dormant at times; if growth slows, reduce watering and allow it to rest before it resprouts.
Perfect for containers, windowsills and conservatories, this plant also works well in sheltered courtyard gardens during summer. Its compact habit makes it ideal for adding colour to small spaces.

Arrived quickly and well-packaged. Planted them in some pots on the patio and they all came up. Look beautiful. Thank you!

The bulbs arrived beautifully packaged and you could just tell they were excellent quality. We had the most wonderful display of daffodils this spring on our patio. Simply stunning. Will definitely be ordering again

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!
