Cultivation details

Prefers full sun and a light sandy dry or well-drained soil[1, 11, 200]. Dislikes damp conditions[1]. Does not require a rich soil, succeeding on marginal land[11]. A very hardy plant but it does not like the lack of sun in British gardens. It is best grown at the foot of a warm dry wall in a well-drained light soil[11]. It prefers a continental climate with hot summers and cold winters[200], it does not flower freely in Britain due to our cooler summers and lack of sunshine[182]. A remarkably curious shrub, but it is not showy[1]. Plants in this genus are notably resistant to honey fungus[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].

Propagation

Seed - best sown as soon as it is ripe in a cold frame[200]. It usually germinates in 2 weeks[K]. Stored seed should be pre-soaked for 24 hours in warm water then sown in a cold frame[78, 113, 200]. If the seed has not swollen then scarify it and re-soak for another 12 hours before sowing[138]. Germination usually takes place within 2 - 3 weeks at 20°c[138]. Good percentage[11]. As soon as they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame[113]. Layering in spring.
