Magnolia grandiflora 'Supergem' is a compact and elegant evergreen magnolia, prized for its smaller size and lush dark green foliage with velvety bronze undersides. It delivers all the classic magnolia beauty in a manageable form for smaller spaces.
Supergem grows to 6-8 metres tall and 3-4 metres wide, with a pyramidal to rounded crown and dense branching. Large fragrant creamy-white flowers, 20-25cm across, appear from late spring through early summer, sometimes flowering sporadically through the season. The compact form suits feature planting, tall privacy screens, and pleaching.
Supergem thrives in well-drained acidic soil, tolerates urban conditions, and is moderately drought tolerant once established. It prefers full sun to partial shade and needs only minimal pruning after flowering to maintain shape, performing well across most Australian climates.
