The stems of the delicate flowers produce seed cases, each containing two seeds. Cultivation A slender and straggly plant, caraway has delicate clusters of white flowers and small feathery leaves. It is most effective when grown in a large clump. Seedlings do not transplant well, so sow in the garden in spring or fall. Work the soil deeply, as caraway is deep-rooted.
Germination is slow.
It thrives in all but the most humid warm regions and does best from fall-sown seeds. The plants should be thinned so that they are about 6 inches apart. It needs well-drained soil and plenty of sun for the best flavor. Harvesting Cut the young leaves when they are required. When the seed turns light brown, cut the whole plant off at ground level.
