Description
Magnolia ‘Susan’ is one of those plants that feels like a little celebration every year. Just as spring is finding its feet, it opens rich, jewel-toned flowers — slender, tulip-shaped blooms in deep purple-pink that stand out beautifully against fresh green growth.
Because it stays neat and compact, ‘Susan’ is a brilliant choice if you’ve always wanted a magnolia but assumed you didn’t have the space. It brings that classic magnolia romance without turning into a giant tree — perfect for smaller gardens, courtyard spaces, or as a focal point in a mixed border.
And the best part? After the main spring show, it often gives a gentle encore in summer, popping out the odd bloom when you least expect it.
Caragh Garden Notebook
- Planting: Choose a sheltered spot and plant carefully — magnolias dislike root disturbance. Dig wide, improve the soil with organic matter, and avoid planting too deep.
- Watering: Keep evenly moist through the first couple of seasons, especially in dry spells. A good mulch helps hugely.
- Feeding: Mulch in spring; an ericaceous compost or leaf mould is ideal if your soil is on the alkaline side.
- Pruning: Minimal pruning required. If needed, prune lightly after flowering to shape — avoid hard pruning.
- Positioning & Design: Place where you’ll see it often — near a path, patio, or window. Looks gorgeous with underplanting like spring bulbs, ferns, or soft evergreen structure.
