Magnolia grandiflora Gallisoniensis, Southern Magnolia
If you want something big, green and that smells a bit lemony in the garden, you could hire the Hulk wearing women’s deodorant or plant a Magnolia grandiflora Gallisoniensis.
A large, evergreen magnolia tree (often known as a southern magnolia) grown for year-round interest, glossy foliage and huge, scented flowers. Magnolia grandiflora Gallisoniensis is one of the more reliable evergreen magnolia trees for UK gardens, forming a dense, impressive tree best suited as a specimen or for larger-scale screening where space allows. This is an evergreen tree that could screen out a fugly shed to an entire building. At maturity, it could even screen out large parts of a flight path!
Upright when young, becoming broad and spreading with age, this evergreen magnolia develops into a full, rounded crown. At maturity it can reach around 10m tall and 10m wide, creating a substantial, dominant evergreen presence in the garden.
The foliage is one of its standout features. Large, thick, glossy dark green leaves are held year-round, with a distinctive brown, felted underside that gives the tree depth and contrast, especially when moving in the wind.
In summer through to autumn, it produces large, white to creamy-white, fragrant flowers up to 25cm across, often described as having a light lemon scent. Appearing gradually instead of all at once, the floral display lasts months instead of weeks. These sit against the dark foliage and provide a strong seasonal highlight.
Magnolia grandiflora Gallisoniensis is best used where you want a tree that provides structure, privacy and presence all year round rather than something purely seasonal.

Planting a Magnolia grandiflora Gallisoniensis, Southern Magnolia

Requires minimal pruning.
The tree can be lightly shaped if needed, but is best left to develop naturally. If pruning is required, carry it out carefully to maintain the overall structure.

Other Information About Magnolia Grandiflora Gallisoniensis, Southern Magnolia
Magnolia grandiflora is native to the south-eastern United States and has been grown in Europe since the 18th century, where it became a popular choice for large gardens and formal planting.
Magnolias are one of the oldest flowering plant groups, evolving before bees, and were originally pollinated by beetles.
The Galissonniere form is considered one of the better cold-tolerant Magnolia grandiflora types, which is why it is more widely planted in the UK than many other evergreen magnolia varieties.
In cooler parts of the UK, it has traditionally been planted against sheltered walls to improve flowering and protect it from cold winds.
