Californian Poppy 'Red Chief' (National Trust)Eschscholzia californicaCalifornia Poppy

Direct sow eschscholzia seed outdoors where they are to grow from March to May or in September for overwintering. Autumn sowings will flower in late spring. Choose a position in full sun on any poor, well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 1cm (1/2") in drills spaced 15cm (6") apart and cover seed with its own depth of soil to exclude light. Water the ground regularly, especially during dry periods. Germination usually takes 14-21 days. When seedlings are large enough to handle, thin them out to 15cm (6") apart.

Alternatively, sow California poppies indoors from February to March at a temperature of 15-21C (60-70F). When seedlings are large enough to handle, transplant and grow them on in cooler conditions until large enough to plant outdoors.
