GrowthFast

Succeeds in warm temperate to subtropical and tropical areas. It is found at low to moderate elevations in Chile, in dry to moist regions where the annual rainfall is in the range of 100 - 800mm and there is a distinct dry season that can be as long as 10 months[1]. Plants can withstand light frosts, but do not tolerate temperatures much below freezing[1]. The plant is recommended for desert or semi-arid conditions, but it is very adaptable and grows successfully in the much moister climate of Kew Gardens in southern England[2]. Prefers a well-drained, circumneutral to slightly acid soil and a position in full sun[3, 4]. Prefers an acid soil with a significant content of organic matter[1]. Established plants are drought tolerant[4]. A fairly fast-growing plant, able to reach a height of 2 metres within two years from seed[1]. The deep-yellow flowers are produced in great abundance and are very fragrant, scenting the air around the tree[4, 2]. 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[5].

Propagation

Seed - best sown as soon as it is ripe in a sunny position in a warm greenhouse[6]. Stored seed should be scarified, pre-soaked for 12 hours in warm water and then sown in a warm greenhouse in early spring. The seed germinates in 3 - 4 weeks at 25°c[7]. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter. Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors. Cuttings of half-ripe wood with a heel, mid summer in individual pots in a frame[8]. Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer. Fair percentage[8].
