(Claytonia perfoliata) AKA Miner’s Lettuce or Winter Purslane. Heart shaped succulent leaves with mild flavour. One of the hardiest of greens, grows well right through the winter in a cold frame or unheated greenhouse- even under the snow. A smash hit in early spring salads! They germinate only in cool weather, and will sometimes sit dormant in the soil until conditions are just right. Easily self sows. Approx. 100 seeds per packet.
