About

Oxalis debilis 'Aureoreticulata' is an Oxalis cultivar recognised for its variegated foliage. It bears pinkish-purple flowers that open in the UK from May to August. In many European plantings the cultivar spreads by bulbs rather than seed. Leaves have a lemony flavour but contain oxalic acid, so eat only small amounts.

In the garden

Oxalis debilis 'Aureoreticulata' is a variegated-leaf form of Oxalis that originated from the species group commonly associated with South America and has become widely planted outside its original range. The cultivar is noted for its variegated leaves and pinkish-purple flowers, which appear in the UK from May to August. In Europe the plants are often sterile and chiefly multiply through bulbs rather than by seed. Plant bulbs where they will not sit in waterlogged soil; the species has been recorded across temperate and warmer climates so choose a position suited to your local microclimate. In cooler UK areas, give a sheltered, frost-free spot or use containers that can be moved under cover if severe winter weather is expected. Bulb clumps can be lifted and divided if they become congested. Use it where the leaf pattern can be seen at close range: gravel or rock gardens, the front of a mixed border, or in patio pots. Because the leaves have a sharp, lemony note but contain oxalic acid, treat any culinary use as a garnish only and avoid large quantities.
