How to Grow Claytonia
Claytonia perfoliata
Claytonia is the ultimate low-maintenance winter salad leaf. Sow from late summer through autumn for winter and spring harvests, or in early spring for a quick cool-season crop. Seeds need cool temperatures to germinate (8-12C ideal) and may be slow to start. Once growing, plants are almost indestructible, surviving hard frosts and poor soil. Harvest the distinctive disc-shaped leaves with the stem piercing through the centre. Cut-and-come-again for months of supply. Prefers partial shade and cool conditions; bolts quickly in warm weather. Self-seeds prolifically, providing free plants year after year.
When to Start
Direct sow outdoors as soon as soil reaches 5°C — typically early to mid spring. Can also be started indoors 3 weeks earlier for a head start.
