Cuminum cyminum aka Cumin

Cuminum cyminum, or cumin, is an annual herb in Apiaceae. It lives for one year. Carrots, celery, and parsley belong to the same plant family. Kew gives its native range as Iraq to Afghanistan. Other sources give a wider range or doubt its origin. People have grown it for a long time. This makes its first wild home hard to trace. Growers raise cumin for seeds in many warm places. These include the Indian subcontinent and North Africa. They also include Mexico and Chile.

The plant grows upright and forms a small, branched bush. Most accounts give a height near 1 foot [0.3 metres]. RHS gives a garden height up to 1.6 feet [0.5 metres]. Its listed spread also reaches 1.6 feet [0.5 metres]. The stems are smooth and thin. They bear green leaves split into fine, narrow parts. These leaves give the plant a light, feathery look. Small white or pink flowers grow in umbels in summer. Each umbel has several small flower groups above the stems. The flowers have both male and female parts. Insects pollinate them. The plant is self-fertile: it can set seed with its own pollen.

Tiny fruits change from green to brown as they ripen. Fine hairs coat the dry fruits. They hold seeds with a strong scent. The seeds have ridges and range from yellow-brown to grey. Cooks use whole or ground seeds in many dishes. Their warm, sharp taste suits curries, soups, stews, and bread. Seed oil adds flavour to food. Makers also use it in perfumes and cosmetics. In folk medicine, people use cumin for gut complaints and other conditions. NC State says modern science has not proved any health benefit. PFAF warns that cumin may lower blood sugar. It urges care for people with diabetes or taking barbiturates.

Grow cumin in full sun and rich soil that drains well. It copes with several soil types and a broad pH range. A warm site with shelter helps the seeds ripen. Good seed crops need three to four warm months. Frost harms the plant; RHS rates it H2. NC State lists USDA zones 5–10, but frost still harms cumin. Water it at set times. Let the soil get almost dry before each soaking. Sow seeds under cover in early spring or outdoors later. Cumin does not cope well when moved to a new site. It needs no pruning.

Cumin suits food gardens, pots, and groups of plants. Its flowers draw insects that pollinate plants. They also draw insects that hunt garden pests. These include ladybugs, lacewings, and wasps that hunt other insects. Harvest ripe, dry seed clusters in late summer or fall. Let the clusters dry fully, then free and store the seeds. RHS reports few pest or disease problems in normal use. NC State lists aphids and fusarium wilt. It also lists alternaria blight and powdery mildew.
