JASMINUM. Widely distributed, both hemispheres. A large group of shrubs and woody vines, valued for both foliage and flowers. Their most consistent feature is the form of the flowers: A narrow tube and widely spreading “face” of several, usually narrow segments. Mostly sun or light shade, fertile soils, moderate to regular watering. Their hardiness is extremely variable.
grandiflorum. Spanish jasmine. A bold, tropical-looking vine with a broad range of climatic tolerance. The stems grow quickly to 10-20’ long but are easily controlled by pruning. Lining them are shiny, deep green, 5- to 7-parted leaves. Plants are decorated by open sprays of pure white, fragrant blossoms from late spring to fall. Evergreen to deciduous, depending on winter temperatures. 15oF or less.
parkeri. Dwarf jasmine. A mounding shrub, eventually 1’ tall and twice that in breadth. The slender branches are dark green when young, neatly lined with divided 1" leaves. In summer—and often sporadically through the year—it is decorated with clusters of 1/2" bright yellow blossoms. A fine shrub for larger rock gardens. Sun, well drained soil, moderate to little watering when established. Probably hardy to 15oF or less.
