Several hardy species are grown for trailing or rambling purposes, and are raised from cuttings or layers. The winter Jasmine, nudiflorum, with yellow flowers on bare stems from November and December to April, is popular; there is a golden-leaved variety of it. The White Jasmine, officinale, flowers from June to September; primulinum is a somewhat tender Chinese species with semi-double bright-yellow flowers, useful for forcing early in the year; revolutum, and fruticans are both evergreen species, the first-named having pinnate leaves, the other ternate ones, both with yellow flowers during the summer months. Other yellow-flowered species are floridum, from China, and humile, a shrubby plant, from India.
