Tagetes tenuifolia, the signet marigold[2] or golden marigold, is a species of the wild marigold in the daisy family (Asteraceae). It is widespread across most of Mexico as well as Central America, Colombia, and Peru.[3][4][5][6][7]

Tagetes tenuifolia is an annual herb sometimes reaching as much as 50 cm (20 inches) tall. Leaves are less than 3 cm (1.2 inches) long, deeply divided into many small parts. The plant produces many small flower heads in a flat-topped array, each head with 5 ray florets and 7-9 disc florets.[8]

Uses

Culinary

The plant's edible flowers can be used as a garnish.

Gardening

Marigolds are regarded as one of the easiest plants to grow. They are very hardy, and may survive minor frosts. The plant is well suited to a mostly sunny position, and fairly well draining soil. Overly fertile soil may cause the plants to become bushy and produce less flowers. Marigolds come in a variety of colours, but mostly yellows and oranges, flowering in the middle of Summer. They can be planted out when there's no more risk of frosts. They can be purchased from most nurseries, and seeds are readily available in stores. It's often used as a companion plant for its insect-repelling properties.

Other

Some species of Tagetes possess a characteristic scent, which repels insects such as mosquitoes, small animals and smaller, burrowing insects. Tagetes tenuifolia is one of these and is often planted near small creeks or puddle prone areas to repel bugs, especially mosquitoes.
