Members of the genus are commonly known as Mexican orange due to the similarity of their flowers with those of the closely related orange, both in shape and scent. They are native to southern North America, from Arizona, New Mexico, Texas and south through most of Mexico. In its generic name Humboldt and Bonpland honoured Swiss botanist Jacques Denis Choisy (1799–1859).[3] DescriptionThe species grow to {{convert|1|-|3|m|ft|abbr=on}} tall. The leaves are opposite, leathery, glossy, palmately compound with 3-13 leaflets, each leaflet {{convert|3|-|8|cm|in|abbr=on}} long and {{convert|0.5|-|3.5|cm|in|abbr=on}} broad. C. ternata has three broad leaflets, while C. dumosa has up to 13 very narrow leaflets. The flowers are star-shaped, {{convert|3|-|5|cm|in|abbr=on}} diameter, with 4-7 white petals, 8-15 stamens and a green stigma; they are produced throughout the late spring and summer. The fruit is a leathery two to six sectioned capsule. UsesChoisya species are popular ornamental plants in areas with mild winters, grown primarily for their abundant and fragrant flowers. The foliage is also aromatic, smelling of rue when bruised or cut. The most commonly found cultivars in the horticultural trade are the species, C. ternata,[4] the golden-leaved C. ternata {{tdes|Sundance}} ('Lich'),[5] and the inter-specific hybrid C. 'Aztec Pearl' (C. dumosa var. arizonica × C. ternata).[6] All three varieties have gained the Royal Horticultural Society's Award of Garden Merit (confirmed 2017).[7]The flowers are also valued for honeybee forage, producing abundant nectar. ChemistryMany quinoline alkaloids have been isolated from leaves of Choisya ternata.[8]C. ternata contains an alkaloid (ternanthranin), a volatile simple anthranilate that can be considered responsible for the antinociceptive activity of the crude plant extracts.[9] Species
Pests and diseasesChoisya can be prone to attack by pythium root rot, particularly when propagated and grown in pots for the horticultural trade. In north-west Europe the main pest is snails, which eat the bark of even mature specimens, resulting in minor die-back of branches where ring-barking has occurred.
