"Green Flowering Shamrock"


Perfect for pots

Loved by pollinators

Hand packed in paper bags

Half Hardy, may need
winter protection


Known variously as the green flowering shamrock, or the green wood sorrel, Oxalis regnellii has large clover-like leaves and dainty white blooms. It’s a South American native beauty that is elegant, graceful—and delightful. In late spring and over summer its flowers of pure-white sweep gracefully from their stems, which rise above the unique, triangular bright green leaves. This is a stand-out feature plant for patio pots, hanging baskets and the front of a border in summer. Or, grow it as a houseplant on sunny windowsills or in conservatories, for autumn and early winter!

Outdoors in the UK, Oxalis regnellii likes a position in full sun or part shade. If growing in a patio pot, it looks particularly handsome in a dark coloured ceramic container. It is, however, frost-tender: it might survive outdoors over winter in warm, sheltered gardens, but expect to give it some winter protection.

Pleasingly, you won’t have to wait long for the little bulbs to bloom! The first flowers usually appear around eight weeks after planting!

  • Plant your little Oxalis bulbs (technically rhizomes) in late spring or autumn, in a pot or straight out into the garden soil after all risk of frost is over
  • Select an area with moderately fertile, humus-rich soil, that is in full sun or part shade
  • If growing in a pot, use a well-drained soil mix of equal parts loam, leaf mould (or soil-less compost) and grit
  • Set the oxalis bulbs 5cm, and space them 13cm apart
  • Water moderately when in growth and, for best foliage and flowers, apply a balanced liquid fertiliser monthly between April and September
  • Outdoors, in late autumn the top growth will die back. Pull or cut this away
  • Provide frost-free conditions for the bulbs to remain dormant over winter. During this time the compost should be kept barely moist
  • To freshen the compost, re-pot the bulbs every couple of years (when dormant), using the same pot, or move up to one size bigger
  • Indoors, pots will remain colourful throughout autumn and early winter. At this stage, allow the oxalis plants to dry out and have a period of dormancy before starting them into growth again in spring
