Cultivation details
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in most parts of this country. This is a convenient name for a complex of apparent hybrids involving A. mollis or A. amplexicaulis with A. cordifolia or A. latifolia[60]. The following notes are based on the general needs of the genus. Prefers a moist, well-drained humus rich soil, preferably lime-free. Prefers a mixture of sand, loam and peat.
Propagation
Seed - sow early spring in a cold frame[200]. Only just cover the seed and make sure that the compost does not dry out. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse or cold frame for their first winter. Plant out in late spring or early summer. Division in spring[200].
