Magnolia Susan (Magnolia soulangeana ‘Susan’) is a truly stunning deciduous magnolia prized for its dramatic, deep purple-pink blooms and reliable spring flowering in New Zealand gardens. Whether you’re a seasoned gardener or just starting out, Magnolia Susan makes a striking statement with its elegant, tulip-shaped flowers and manageable size—perfect for smaller spaces or as a feature tree.

Magnolia soulangeana Susan

Magnolia soulangeana ‘Susan’ is a compact, deciduous magnolia valued for its rich, deep pink to purple, tulip-shaped flowers that appear in early to mid-spring.

Why Choose Magnolia Susan for Your New Zealand Garden?

If you’re seeking a flowering tree that combines beautiful colour, compact growth, and easy care, Magnolia Susan is an excellent choice. This variety is part of the “Little Girl” series, specially bred for their profusion of spring and late-spring flowers. Magnolia Susan’s upright habit and relatively modest height—typically reaching 3 to 4 metres—make it perfect for urban gardens, mixed borders, or even as a show-stopping specimen in a courtyard.

Unlike some other magnolias, Magnolia Susan boasts strongly coloured fuchsia-purple flowers with paler insides. These open just as the leaves start to emerge, creating a captivating contrast in early to mid-spring. The slightly fragrant blossoms not only attract garden admirers but also pollinators, bringing your outdoor space to life.

Planting and Care Tips for Magnolia Susan

Magnolia Susan thrives in most New Zealand climates, preferring a sheltered spot with full sun to partial shade. Plant in well-drained, humus-rich soil and water deeply during dry periods, especially in the first few years as the tree establishes. Magnolia Susan is relatively low maintenance but benefits from a mulching layer around the base to keep roots cool and moist.

Consider pruning only lightly to maintain shape, as heavy pruning may reduce next season’s flower production. Avoid planting too deeply, and try not to disturb the root system, as magnolias can be sensitive when transplanted.

Pairing Magnolia Susan with Other Flowering Trees

To maximise seasonal interest, plant Magnolia Susan alongside other eye-catching magnolias, such as Magnolia stellata Waterlily with its starry white blooms, or the dramatic Magnolia Star Wars. For contrasting flower colours and longer blooming, try Magnolia grandiflora Little Gem or the aromatic Magnolia DD Blanchard.

Gardeners with a love for bold colour might also consider Magnolia Genie, which features rich, burgundy-red flowers throughout the spring season. Underplanting with spring bulbs or complementing with foliage contrast—like the Acer x freemanii Marmo (Marmo Maple Tree) or Betula pendula Purple Splendour—adds even more impact.

Magnolia Susan: Ideal for Urban and Rural Gardens

Magnolia Susan’s manageable size and outstanding floral display make it a great choice for both urban backyards and larger rural gardens. It’s well-suited for informal hedging, as a standalone feature, or as part of a mixed woodland planting with trees like Fraxinus ornus or Nothofagus cunninghamii (Myrtle Beech).

For those looking to create screening or add evergreen structure, mix in plants such as Pittosporum Pinnacle for year-round interest.
