Magnolia 'Coolwyn Gloss' is the showroom-clean evergreen Magnolia. Extra-glossy dark green leaves, rich brown felted undersides, large perfumed white flowers and noticeably lower leaf drop than other cultivars in the range. It is the polished pick when you want Magnolia grandiflora character with a contemporary finish.
What makes Coolwyn Gloss distinct
The leaf gloss
Every evergreen Magnolia has glossy leaves; Coolwyn Gloss takes it a step further. The upper leaf surface has a higher shine that catches the light, especially on new growth. The brown felted underside provides warm contrast and gives the foliage real depth in the landscape.
The flowers
Large creamy white cup-and-saucer flowers up to 15 cm across, perfumed with the classic Magnolia lemon-citrus scent. Flowering starts in late spring and continues in flushes right through summer.
Low leaf drop
Coolwyn Gloss has lower leaf shed than Little Gem or Teddy Bear. Useful around pools, patios and entries where a clean finish matters.

Design uses
Feature tree
A single specimen by the front entry, on a back lawn or in a courtyard delivers polished evergreen impact. Plant where the foliage will catch afternoon light.
Privacy screen
Plant 1.5 metres apart in a single line, or stagger for a denser block. Coolwyn Gloss can be pruned to desired height once established.
Hedge
Spaced at 1.2 metres apart and lightly tip-pruned from young, Coolwyn Gloss creates a formal evergreen hedge with the same clean finish as the standalone tree.
Planting
Full sun gives the strongest flowering, with part shade tolerated in hot inland positions. Well-drained soil is essential. Dig a hole twice the rootball width, plant at the same depth as the pot, backfill with compost-enriched soil and water in deeply.
Care
Deep weekly watering through the first two summers. Mulch out to the drip line with 7 to 10 cm of bark or sugarcane, kept off the trunk. Feed in early spring with a balanced slow-release fertiliser; a second light feed after the first flowering flush extends the show.
Light tip pruning encourages density and shape. Avoid heavy pruning into old wood.
How it compares
Teddy Bear is denser and more compact, with bronze leaf reverses and a warmer tone. Little Gem is the narrower upright benchmark with a slightly more open habit and rusty undersides. Kay Parris adds wavy leaf edges and a relaxed feel. Each is covered in the recommendations panel.
