Jasmine is famous for the heady scent of its pure-white flowers that are set off by dark-green, glossy leaves. Jasmine is a common name that technically belongs to plants in the genus Jasminum but is used also for night blooming jasmine, confederate and Asiatic jasmine. Jasmine is available in vine, shrub and ground cover varieties.
Confederate Jasmine (Trachelospermum jasminoides)
Climbing sturdy trellises, fences, light posts and even trees, confederate jasmine is a popular landscape vine throughout USDA plant hardiness zones 7 through 10 where it grows well. Confederate jasmine produces small pinwheel flowers that, like most jasmine, are incredibly fragrant. The white flowers appear among dark-green leaves along a woody stem. This jasmine must be provided a sturdy support. There are several noteworthy hybrids of this jasmine including Variegatum with its green and white leaves and Japonicum with white-veined leaves. Confederate jasmine tolerates a wide range of soils and prefers full sun but will bloom in partial shade.
Night Blooming Jasmine (Cestrum Nocturnum)
Night blooming jasmine is an evergreen shrub in USDA zones 10 to 11 where it is hardy. This shrub is frequently used in zones 8 and 9 where it dies back in the winter if temperatures drop into the thirties. As the name implies, the sprays of tubular flowers open at night and perfume the evening air with a marvellous fragrance. The leaves are bright-green and glossy. Night blooming jasmine tolerates a wide range of soils and grows in sun or partial shade.
Asiatic Jasmine (Trachelospermum asiaticum)
Low-growing Asiatic jasmine is promoted as a replacement for turf grass in USDA zones 7 to 10 where it grows well. Asiatic jasmine is a vine with a prostrate form useful as a ground cover. It is evergreen and withstands drought and cold once it is established. Forming a dense mat of dark-green leaves, it is attractive and requires little maintenance. An annual mowing helps promote even growth and allows air to circulate, preventing mould. Asiatic jasmine thrives in full shade where turf grass does not do well. The flower of Asiatic jasmine is not noticeable or fragrant.
Common White Jasmine (Jasminum officinale)
The common white jasmine can be used as a shrub or a vine. As a shrub, it requires frequent pruning to prevent a lanky appearance. As a vine, it requires a sturdy arbor or trellis to support its heavy stems. Common white jasmine produces remarkably fragrant white flowers throughout the fall and summer months. The leaves are dark-green and glossy. It does well in a variety of soil types in full sun or partial shade. Common white jasmine grows in zones 7 to 10, although it may die back when temperatures drop into the thirties.
