Mexican-orange is a dense evergreen shrub. Mature height may range from 6-8’ high and just as wide. Not only are the white 1-1.25” flowers fragrant but the green foliage has a distinctive odor. Flowering from May to June and will occasionally bloom for longer periods. Growing best in a well drained acidic soil, this evergreen is cold hardy to about 5 degrees (suggested zones 7-9), however I have seen it survive colder temperatures.

A notable cultivar of this species is ‘Sundance.’ Bressingham Gardens, England, introduced Sundance in the late 19th century. Its foliage is a golden yellow that is similar to the species in flower and habit.
