Oxalis bulbs grow into charming, characterful plants with delicate flowers and beautifully shaped foliage. Often known as wood sorrel or shamrock, the genus includes an intriguing variety of forms, from low-growing plants covered in jewel-like blooms to richly coloured foliage varieties such as Oxalis triangularis. Their leaves may be fresh green, deep purple or finely patterned, while the flowers appear in shades of white, pink, yellow and soft lilac. Many varieties open their leaves and flowers in daylight before gently folding them as evening approaches.

Our Oxalis bulbs are ideal for adding colour and fine detail to patio pots, window boxes, indoor containers and suitable garden borders. They look particularly effective planted in generous groups, where their neat foliage creates a full display beneath the light, airy flowers. Compact varieties are easy to combine with other bulbs and seasonal plants, while the most distinctive foliage types deserve a pot of their own. Although commonly sold as Oxalis bulbs, different varieties may grow from true bulbs, rhizomes or small tubers.

Plant Oxalis bulbs in free-draining soil or peat-free compost, following the specific instructions for your chosen variety. Their hardiness varies: some Oxalis varieties can grow outdoors in suitable conditions, while tender types need protection from frost and are best brought indoors for winter. During dormancy, the foliage may naturally disappear for a time. Reduce watering while the plant rests, then resume as fresh growth emerges. Explore our Oxalis bulb collection to find graceful flowers, fascinating foliage and something refreshingly different for your planting displays.
