Choisya

Compact shrubs with sweetly scented white flowers in late spring, held in clusters above aromatic evergreen leaves. Choisya ternata Sundance ('Lich') has golden-yellow leaves, while those of Choisya × dewitteana ‘Aztec Pearl’ are narrower, giving a less dense appearance.

Choisyas grow well in most soil types, provided they aren’t overly wet or very dry. They prefer a sunny position, although they can cope in light shade. A sheltered site, such as against a warm wall, is ideal, especially for more tender cultivars. Good for containers.

Choisyas dislike soil that stays damp for long spells, and a very exposed position may lead to some damage to foliage.

Known as Mexican orange blossom, this shrub is indeed related to oranges (and other citrus). Like them, its leaves release an aromatic oil when crushed, but it’s from the flower fragrance that it gets its common name.
