Cultivation details
Landscape Uses:Erosion control. Prefers a light well-drained sandy soil in sun or light shade[200]. Fairly wind-resistant[200]. A very hardy plant, tolerating temperatures down to about -25c[200]. Plants resent root disturbance, they should be planted out into their final positions whilst small[133]. Plants are said to be immune to insect pests[200]. Flowers are produced on the current season's growth[200]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. Special Features:Invasive, Naturalizing, Attractive flowers or blooms.
Propagation
Seed - presoak for 12 hours in warm water and sow early spring in a greenhouse[78, 133]. The seed usually germinates in 1 - 2 months at 20°c[133]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, June/July in a frame. High percentage[78]. Cuttings of mature wood of the current seasons growth, autumn, in a sheltered position outdoors. Takes 12 months[78]. Suckers in spring just before new growth begins[200]. Layering in spring .
