JASMINUM

When one thinks of fragrance, jasmine is one of the first plants that comes to mind.

Growth habits of jasmines range from vining to vining-shrubby to decidedly shrubby. True vining types climb by twining stems. Vining shrubs do not twine, but rather put out long, slender, lax stems that must be tied into place if the plants are to function as vines. Otherwise, they’ll flop over to make green haystacks of foliage. To grow these plants as shrubs, shorten any shoots that become too long. Only one of the species listed below, Jasminum parkeri, is a true shrub; its dwarf size suits it to rock gardens.

Jasmines grow more rapidly in good soil and bloom more profusely in sunny sites, but all adapt well to less-than-perfect conditions. When plants become tangled or untidy, cut them back heavily just before spring growth begins. Pinch and prune as needed throughout the year to control growth.

For information about star jasmine (not a true jasmine), see Trachelospermum jasminoides.
