Cultivation details

Grows best in a woodland soil in partial shade[1, 200]. The soil should be lime-free, moist, well-drained and moderately rich[200]. Dislikes full sun and windy positions[200]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. A very ornamental plant[1]. Monocarpic, the plants living for a number of years before flowering but then dying once they flower[200]. A fine plant for growing in open woodland[1]. Plants are subject to 'crown rot' when they are growing in damp conditions[1].
