Requires a well-drained moderately fertile soil in a sunny position. Grows well in heavy clay soils and in sandy soils. Although not very frost resistant, it can be grown as a tender annual in Britain, sowing the seed in a greenhouse in the spring and planting out after the last expected frosts. The flowers are often sold in local markets in Nepal and used as an offering to the Gods. A number of named forms have been developed for their ornamental value. The cultivar ‘Yellow Climax’ has mild flavoured edible flowers that can be used as colourful garnishes. All parts of the plant emit an unpleasant smell similar to that of stale urine when they are bruised. Removing dead flowers before the seed is formed will extend the flowering season. Plants are prone to attacks by slugs, snails and botrytis.
Seed – sow March in a greenhouse. Only just cover the seed. Germination usually takes place within 2 weeks. When they are large enough to handle, prick the seedlings out into individual pots and plant them out after the last expected frosts.

A yellow dye obtained from the flowers can be used as a saffron substitute for colouring and flavouring foods. The plant is used as a condiment.

It is most effective against the nematode species Pratylenchus penetrans
Dye; Insecticide; Repellent.
Secretions from the roots of growing plants have an insecticidal effect on the soil, effective against nematodes and to some extent against keeled slugs. These secretions are produced about 3 – 4 months after sowing. The flower petals also have nematacidal properties. The growing plant is also said to repel insects and can be grown amongst crops such as potatoes and tomatoes. A yellow dye is obtained from the flowers.
Its flower, the cempasúchil is also called the flor de muertos (“flower of the dead”) in Mexico and is used in the Día de los Muertos celebration every 2nd of November. The word cempasúchil (also spelled cempazúchil) comes from the Nahuatl term for the flower zempoalxochitl, literally translated as “twenty flower”.
