Plants are not very hardy outdoors in Britain though the rootstock can tolerate temperatures down to about -10°c provided the stem bases are 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].
A form called 'Compacta' is said to flower more freely than the type[233].
Plants take 3 - 4 years to flower from seed[200]. Plants are difficult to establish, taking some years to flower[202].
