Tagetes lemmonii

provided by wikipedia EN

Tagetes lemmonii, or Lemmon's marigold,[1] is a North American species of shrubby marigold, in the family Asteraceae. Other English names for this plant include Copper Canyon daisy, mountain marigold, and Mexican marigold.[2]

It is native to the states of Sonora and Sinaloa in northwestern Mexico as well as southern Arizona in the United States.[3][4]

Description

Tagetes lemmonii is a shrub sometimes reaching as much as 240 cm (8 feet) tall.

Leaves are up to 12 cm (4.8 inches) long, pinnately compound into 3-5 leaflets, each leaflet narrowly lance-shaped with teeth along the edge.

The plant produces many small flower heads in a flat-topped array, each head with 3-8 ray florets and 12-30 disc florets. It grows in woodlands, cliffs, and moist sites.[4]

Taxonomy

The species is named for John Gill Lemmon, husband of American botanist Sarah Plummer Lemmon.[5]

Cultivation

Tagetes lemmonii blooms from fall into spring and can sometimes be blooming for up to 10 months. It can get up to 8 feet tall by across. The foliage is pungent when disturbed. The species is very drought tolerant in a Mediterranean climate and much used in California gardens where it tolerates light frosts without damage.

Tagetes lemmonii

L'espèce Tagetes lemmonii appartient au genre Tagetes de la famille des marguerites (Asteraceae).Il s'agit d'une espèce indigène de l'Amérique du Nord, originaire des États du Sonora et du Sinaloa, dans le nord-ouest du Mexique ainsi que dans le sud de l'Arizona aux États-Unis[2],[3].

Description

Tagetes lemmonii est une plante herbacée vivace atteignant parfois plus de 100 cm de haut pour 80 cm de large.

Les feuilles vertes finement découpées peuvent atteindre jusqu'à 12 cm de long, et sont composées pennées avec 3-5 folioles étroitement lancéolés et dentés.

La plante produit de nombreux petits capitules regroupés en corymbes. Chaque capitule comprend 3-8 fleurs ligulées et 12-30 fleurons[3].

Étymologie

Le genre est nommé d'après Tagès, une divinité étrusque qui aurait émergé de la terre tout juste labourée. Ceci fait référence aux tiges printanières qui percent le sol lors du rejet de souche[4].

L'espèce est nommée en l'honneur de John Gill Lemmon, mari de la botaniste Américaine Sarah Plummer Lemmon[5].

Utilisation

Tagetes lemmonii est caractérisé par sa floraison automnale tardive, qui peut se prolonger jusqu'au printemps si la plante n'a pas gelé en hiver.

Lorsque le feuillage est frotté, il dégage une forte odeur piquante, fraîche et acidulée, mêlant des senteurs de mandarine, persil et menthe[4].

Cette espèce très tolérante à la sécheresse en climat Méditerranéen est très utilisée dans les jardins Californiens où elle tolère sans dommage de brèves gelées.
