Claytonia perfoliata

Winter purslane, Claytonia perfoliata, is sometimes called miner's lettuce, and is typically used in winter salads. One of the hardiest salad crops available, it has heart-shaped, slightly succulent leaves, with a mild flavour. Both the leaves and flowering shoots can be eaten.

It self-seeds rapidly and can become invasive, although seedlings are shallow rooted and can be easily removed. Sow winter purslane in late summer for an autumn to early winter harvest, or in spring for a summer crop.
