Magnolia ‘Susan’

Magnolia ‘Susan’ is a cross between M. liliiflora ‘Nigra’ and M. stellata ‘Rosea’ and it was developed at the National Arboretum in the mid-1950s by Francis DeVos and William Kosar. Awarded the RHS Award of Garden Merit (AGM).

Magnolia ‘Susan’ is slow-growing compact and bushy shrub or small tree with fragrant fuchsia flowers with paler tones inside, and late bloom in spring. Usually open before the leaves appear. Flowers may sporadically repeat bloom in midsummer. Leaves turn yellow-bronze in fall.

Grow in any normal garden soil, moist but well drained in full sun or partial shade. Will perform best if planted in full sun and sheltered from cold winds.

Can be pruned in midsummer once flowers have faded. Flowers are produced on last season's growth, so the only pruning necessary is to trim and shape. Apply a mulch of well rotted compost in the autumn.

The best way to propagate Magnolia Susan is to take softwood cuttings in late spring or early summer. Cuttings can be slow to root so some bottom heat is recommended.
