Cultivation Details
Sunhangia elegans has moderate cold resistance, being able to tolerate temperatures down to around -15 to -20°c when dormant[1, 2]. It grows best in areas with long, hot summers[3]. Succeeds in most soils so long as they are well-drained[4, 2]. Requires a sunny sheltered position[5, 4]. Requires long hot summers to be at its best, the flowers are produced on the current years growth and do not open in cold wet seasons[3]. Plants send up new shoots 100 - 150cm long annually from a woody base[3]. If the plant is not cut back to the ground by winter cold then it is best to prune it hard in late winter in order to encourage better flowering[4]. 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[2].
Propagation
Seed - best sown as soon as it is ripe in a greenhouse. Scarify and pre-soak stored seed for 5 hours in warm water then sow early spring in a greenhouse. The seed usually germinates within 1 - 4 months at 25°c. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in the greenhouse for their first winter. Plant them out in late spring or early summer and consider giving them some protection from frost in their first winter outdoors. Cuttings of half-ripe wood with a heel, mid summer in a frame. Division as the plant comes into growth in the spring. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Root cuttings in winter. Cite as: Temperate Plants Database, Ken Fern. temperate.theferns.info. 2026-02-21. <temperate.theferns.info/plant/Sunhangia+elegans>
