Cultivation details

Requires a moderately fertile well-drained soil in a very sunny position[200]. Best if given the protection of an east, south or south-west facing wall[200]. Plants are not very hardy outdoors in Britain though they experience at least moderate frosts in their native range and would be worthwhile trying outdoors in the very mildest areas of this country[200]. They can tolerate occasional lows to about -5°c[260]. The stem bases should be thickly mulched with organic matter such as leaf litter or sawdust and covered with bracken[200]. The top growth will be killed by the frost but new growth from the rootstock will flower in late summer[200]. Plants take 3 - 4 years to flower from seed[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].
