Cultivation details
Easily grown in a moist well-drained soil in sun or semi-shade[187]. Succeeds in ordinary garden soil but prefers a rich sandy loam[1]. Requires a damp soil, doing well by water[1, 111]. A very ornamental plant[1], it is hardy to about -20°c[187]. This species is closely related to A. narcissiflora[233]. Plants seem to be immune to the predations of rabbits[233]. A greedy plant, inhibiting the growth of nearby plants, especially legumes[54].
Propagation
Seed - best sown in a cold frame as soon as it is ripe in the summer[1]. Surface sow or only just cover the seed and keep the soil moist. Sow stored seed as soon as possible in late winter or early spring, it requires 3 - 5 weeks cold stratification. The seed usually germinates in 1 - 6 months at 20°c[133]. When large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first year in a lightly shaded place in a greenhouse. When large enough, plant them out into their permanent positions in the spring. Division in late summer after the plant dies down.
