Choisya  has a wonderfully scented, star-shaped, white flowers appear in late spring among glossy, aromatic, dark green leaves. This handsome, compact and easy-to-grow shrub is a valuable garden mainstay for a protected site in sun or part shade, although in shade it may not flower. The glossy, evergreen leaves provide an excellent backdrop for medium-sized perennials and pale-grey or purple foliage plants.Prune established plants in spring immediately after flowering, removing 25-30cm (10-12in) of the flowered stems.
