Tagetes patula, the French marigold, [3] [4] is a species of flowering plant in the family Asteraceae, native to Mexico and Guatemala [5] with several naturalised populations in many other countries. It is widely cultivated as an easily grown bedding plant, with thousands of different cultivars in brilliant shades of yellow and orange.

Contents

Some authorities regard Tagetes patula as a synonym of Tagetes erecta , the Mexican marigold. [6]

Name

The Latin specific epithet patula means “with a spreading habit”. [7]

Description

Tagetes patula is an annual, occasionally reaching 0.5 m (1.6 ft) tall by 0.3 m (1.0 ft) wide. In some climates it flowers from July to October. In its native habitat of the highlands of central Mexico, blooms are produced from September to killing frost. Achenes ripen and are shed within two weeks of the start of bloom. The heads contain mostly hermaphrodite (having both male and female organs) florets and are pollinated primarily by beetles in the wild, as well as by tachinid flies and other insects. The leaves of all species of marigold include oil glands. The oils are pungent. [8] It can grow in both sandy and clay soils provided they have good drainage. It requires full sun to partial shade.

Cultivation

This plant is valued for its velvet-textured, brightly coloured blooms in shades of yellow, orange and brown in summer. It is shorter, and has a more spreading habit, than its relative the Mexican marigold (Tagetes erecta). It is therefore more suitable as an edging plant in the open border. [10]

The plant is used in companion planting for many vegetable crops. Its root secretions are believed to kill nematodes in the soil and it is said to repel harmful insects, such as white flies on tomatoes. [11] Moreau et al 2006 attempted to protect Solanum tuberosum against Leptinotarsa decemlineata by intercropping with T. patula but instead found it acting as an attractant, resulting in greater infestation and lower yields. (They also found the same for another purported repellent, Armoracia rusticana .) [12] [13]

Tagetes patula is frost intolerant, given a Royal Horticultural Society hardiness rating of H2, capable of surviving temperatures of 1–5 °C (34–41 °F) but killed by freezing temperatures. [14] They are grown by gardeners in moderately fertile, but well-drained soil in full sun with evenly moist conditions. [15]

Cultivars

Hundreds of cultivars have been developed, of which the following have gained the Royal Horticultural Society's Award of Garden Merit:- [16]

  • 'Bonanza Flame' [17]
  • Bonanza Series [18]
  • 'Dainty Marietta' [19]
  • 'Disco Orange' [20]
  • 'Disco Yellow' [21]
  • 'Fireball' [22]
  • 'Hero Orange' [23]
  • 'Honeycomb' [24]
  • 'Queen Sophia' [25]
  • 'Safari Mixture' [26]
  • 'Safari Scarlet' [27]
  • 'Safari Tangerine' [28]
  • 'Tiger Eyes' [29]
  • 'Yellow Jacket' [30]
  • 'Zenith Golden Yellow' [31]
  • 'Zenith Lemon Yellow' [32]
  • 'Zenith Yellow' [33]

Other uses

Medicinal

Medicinally, many cultures use infusions from dried leaves or florets. [8] Research also suggests that T. patula essential oil has the ability to be used as residual pesticide against bedbugs. [34]

The essential oil is being investigated for antifungal activity, including treatment of candidiasis [35] and treating fungal infections in plants. [36] [37]

Culinary

The dried and ground flower petals constitute a popular spice in the Republic of Georgia in the Caucasus, where they are known as imeruli shaphrani (= 'Imeretian Saffron') from their pungency and golden colour and particular popularity in the Western province of Imereti. The spice imparts a unique, rather earthy flavour to Georgian cuisine, in which it is considered especially compatible with the flavours of cinnamon and cloves. It is also a well-nigh essential ingredient in the spice mixture khmeli suneli, which is to Georgian cookery what garam masala is to the cookery of North India - with which Georgia shares elements of the Mughlai cuisine. [38]

Colouring

Tagetes patula florets are grown and harvested annually to add to poultry feed to help give the yolks a golden color. The florets can also be used to color human foods. [8] A golden yellow dye is used to color animal-based textiles (wool, silk) without a mordant, but a mordant is needed for cotton and synthetic textiles. [8]

Fragrance

The whole plant is harvested when in flower and distilled for its essential oil. The oil is used in perfumery. It is blended with sandalwood oil to produce 'attar genda' perfume. About 35 kg (77 lb) of oil can be extracted from 1 hectare (2.5 acres) of the plant yielding 2,500 kg (5,500 lb) of flowers and 25,000 kg (55,000 lb) of herbage.

Typically growing to 60 cm (24 in) tall, they bear showy double flowers up to 6 cm (2.4 in) in diameter. Flowers appear in shades of cream, yellow and orange. The curved “petals” are actually sepals, surrounding the smaller, nectar-bearing petals. The spherical or cupped shape of the blooms gives rise to the common name globeflower, which they share with other Trollius species.
