Tagetes micrantha is a ANNUAL growing to 0.3 m (1ft) at a fast rate.
See above for USDA hardiness. It is hardy to UK zone 7 and is frost tender. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. The plant is self-fertile.
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Other Uses
Companion
Many members of this genus are widely used in companion planting schemes[238]. 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[200]. These root secretions also have a herbicidal effect, inhibiting the growth of certain plants growing nearby. It has been found effective against perennial weeds such as Ranunculus ficaria (Celandine), Aegopodium podagraria Ground elder), Glechoma hederacea (Ground ivy), Agropyron repens (Couch grass) and Convolvulus arvensis (Field bindweed)[200, 238]. An essential oil distilled from the leaves and flowering stems, harvested when the plant is forming seeds, is used as an insect repellent[46, 61]. It is also used in perfumery[238]. Dried plants can be hung indoors as an insect repellent[238]. Dynamic accumulator.

Cultivation details
Requires a well-drained moderately fertile soil in a sunny position[200]. Plants are not very resistant to frosts and need to be grown as half hardy annuals. Removing dead flowers before the seed is formed will extend the flowering season[188]. Most members of this genus are very good companion plants, see 'Other Uses' below for more details[238]. Plants are prone to slugs, snails and botrytis[188]. Tagetes micrantha, commonly known as licorice marigold, is a hermaphroditic plant, meaning it possesses both male and female reproductive organs. While specific information on its self-fertility is limited, many Tagetes species are capable of self-pollination. However, they are typically pollinated by insects, which can enhance seed production and genetic diversity.
