When the weather is cold and bleak the attractive arching green stems of winter jasmine promise one of the first harbingers of spring; bright yellow flowers borne about a month before forsythia. A native of northern China, winter jasmine is a very versatile plant that can be grown as a ground cover, on a trellis or wall, cascading down a slope, or as a bonsai. When the glossy green leaves appear after the flowers, the plant adds a fine texture to the garden.
