Magnolia grandiflora 'Coolwyn Gloss' is a striking evergreen magnolia selected for its exceptionally glossy dark green foliage and large fragrant white flowers. The lacquer-like sheen of the leaves, set against bronze undersides, gives it a richness and presence that sets it apart from other evergreen magnolias.
Coolwyn Gloss grows to 9-12 metres tall and 6-9 metres wide, making it one of the larger evergreen magnolia cultivars. The substantial size and dense habit suit avenue planting, large feature positions, and tall privacy screens, where compact cultivars like Teddy Bear and Little Gem are better for smaller gardens.
Coolwyn Gloss is adaptable across most Australian climates, preferring well-drained, slightly acidic soils and full sun to part shade. It is low maintenance, drought tolerant once established, and pest resistant, producing large fragrant white flowers through late spring and summer.
