Magnolia liliiflora ‘Nigra’, the black lily magnolia, is a beautiful shrub that eventually becomes a small, multi-stemmed tree. It’s grown for its sumptuous, large, tulip-shaped flowers that are deep purple-red on the outside, paler on the inside. They appear later than most magnolias – mostly in late spring and early summer, then sporadically through to early autumn.
As Magnolia liliiflora ‘Nigra’ only reaches around 4m x 2.5m, it is suitable for a smaller garden. Unlike many magnolias, it’s deciduous.
Grow Magnolia liliiflora ‘Nigra’ in a sun or partial shade, sheltered from strong winds. Magnolias do best in moist but well-drained, neutral to acid soil. When planting, add plenty of well rotted manure or garden compost to the planting hole, then add a mulch of rotted bark chips or manure, leaf mould or garden compost afterwards. Continue to mulch each spring and keep well watered until established.
Late frosts may damage flower buds, so cover the plant with fleece if possible if low temperatures are forecast. Magnolia liliiflora ‘Nigra’ does not need pruning – trim to maintain its shape or remove any broken or crossing branches in midsummer.
Magnolia liliiflora ‘Nigra’ holds the prestigious RHS Award of Garden Merit.
