It is harvested from the wild for local use as a medicine..
Southern N. America - Mexico.
Chalky soils, often near the sea[
Requires an open sunny but sheltered position[
]. Plants can be damaged by cold winds[
]. Plants grow equally well whether in full sun or in deep shade[
]. They succeed in most soils[
], but prefer a rather light loam[
]. They require a well-drained soil, tolerating drought once established and atmospheric pollution[
A very ornamental plant[
], it usually survives very severe winters in Britain but can be damaged in spells of lesser cold, especially in the New Year[
]. Plants are normally undamaged at temperatures around -10°c but can be defoliated at -15°c[
]. Whole branches have a habit of dying for no apparent reason[
The Mexican orange flower is moderately fast growing when young, but it soon slows down with age[
]. The plants are very tolerant of pruning and can be cut right back to the ground if required[
]. Pruning is generally unnecessary for this species, apart from cutting out frost-damaged wood[
Some named forms have been selected for their ornamental value[
The flowers appear mainly in late spring[
], but plants can produce a few flowers in the autumn[
]. They often also flower intermittently all through the summer[
]. The flowers are borne at the shoot tips[
The crushed foliage has a pungent aromatic scent of oranges[
] and the flowers are sweetly fragrant with the powerful aroma of orange blossom[
Plants in this genus are notably resistant to honey fungus[
Plants can be grown as an informal hedge, they also respond well to clipping and so can be grown in a more formal manner[
Seed - sow spring in a greenhouse[
]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Cuttings of half-ripe wood, 6 - 8cm long, early July in gentle heat in individual pots in a frame[
]. High percentage[
Cuttings of almost ripe wood, 10 - 15cm with a heel, August in a frame. Good percentage. Plant out in spring[
