Stock 'Night Scented' - Kew Pollination Seed CollectionMatthiola longipetala subsp. bicornisMatthiola bicornis

Direct sow Stocks seeds outdoors where they are to grow from March to June. Choose a position in full sun on any well drained soil which has been raked to a fine tilth. Sow seeds thinly, at a depth of 6mm (¼in) in drills spaced 30cm (12”) apart and cover the seed with its own depth of soil to exclude light. Water the ground regularly, especially during dry periods. Germination usually takes 7 - 14 days. When Stock seedlings are large enough to handle, thin them out to 20cm (10”) apart.
