We were so thrilled to hear that there was a hardy version of such an unusual and beautiful shrub like evergreen Mexican orange. It is an interspecific hybrid between choisya ternata with wider leaves that is often cultivated in South Europe and in England, and hardier choisya dumosa var. arizonica which has narrow leaves and comes from Arizona and Texas where, though used to hot weather, it withstands all sorts of unpleasant conditions including the ability to grow in elevations up to some 1200m. Choisya name was chosen in honour of Swiss botanist Jacques Denis Choisy (1799-1859), and the hybrid was named choisya x dewitteana (official approval of new botanical name pending). It was bred by Peter More from England and the very first variety from 1989 was called Aztec Pearl.
Description of the plant:
APPLE BLOSSOM is another of English beauties among hybrid choisias bred by their father Peter Moore. It is renowned for very fine foliage, and also is the very first to offer romantic pink colour. From late April until early June appear small, pearl-like, clear pink buds which open into apple-blossom-like, star-shaped, white flowers with pink undersides. The centre is decorated with a crown of yellow anthers. Their perfume is similar to that of orange flowers hence its name Mexican orange or Mexican blossom. The evergreen leaves are lace-like, palmately divided into 7 very narrow, thread-like, dark green leaflets. Leaflets, stalks as well as younger branches are covered with puzzling, miniature humps which provide a 3 dimensional feeling. Leaves release a tempting spicy scent when crushed, yet please do not consume them. They are very resistant to winter sun scorch even in winters of zone 6 and remain lush and handsome all year round. APPLE BLOSSOM seems to perform better in light to partial shade but can cope with full sun, too. It forms an upright, more slender shrub than its parent, reaching just above one meter in about 10 years. Thanks to its lacy foliage it looks delicate and fluffy, and will soften any landscape as a perfect companion for large-leaved plants.
The hybrid was sold predominantly in England, where it was among the top ten best selling plants for 20 years, later in the Netherlands and France, and now in Italy where it battles with the original c. ternata. Only recently it was introduced to slightly colder parts of Europe as it proved to be hardier than older varieties of cherry laurels and photinias which had a problem during the cold winter of 2010, and a few more afterwards. So far it survived -23°C without any damage which makes it hardy to USDA zone 6.
Grow choisya the same way as a sun loving rhododendron. It has shallow and delicate root system which must never stand in wet ground. Drainage is crucial for its happy life, and so is acid, fertile soil for its healthy look. We highly recommend using mycorrhiza that will help the plant establish sooner and provide enough nutrients. As it flowers from mid spring (on last year’s wood) pruning of any kind should happen immediately after flowering in early summer. If you follow these instruction you can enjoy a gorgeous plant for many years had without virtually any maintenance.
