Description
The Magnolia grandiflora 'Galissonière' is a tree with large white flowers, fragrant and tulip-shaped, reaching a height of 10 to 15m (32.8 to 49.2 ft) at maturity.
Originally from North America, the 'Galissonière' Magnolia is a naturally rounded tree, hardy down to -15°C, with slow growth. The evergreen leaves are alternate, simple, and entire, glossy green on top and dull bronze underneath. The large tulip-shaped flowers, 15cm (5.9 in) in diameter, are delightfully scented and appear from June to September. Afterwards, it develops large, reddish cones that are quite decorative.
The Magnolia grandiflora 'Galissonière' prefers a rich, moist, even wet soil in summer, in a good forest soil (pH6). It appreciates light sun or partial shade, sheltered from prevailing winds. Beware of severe frost and hot, dry summers. Maintain good humidity by lightly misting the leaves in the evening. Pruning is unnecessary.
The Magnolia grandiflora 'Galissonière' can be placed as a solitary tree or in a free hedge, but is especially recommended in a strategic location to admire in the garden and enjoy its lemony fragrance.

Planting and care
Magnolia grandiflora 'Galissonière' should be planted in the spring in rich, moist, or even wet ground, in good forest soil (pH6). It prefers a site in light sun or partial shade, sheltered from prevailing winds. On planting be careful not to break the fleshy roots and not to bury the root ball too deeply. Mulch and water in the summer. Beware of heavy frosts and hot, dry summers. Maintain good humidity by showering its foliage with a fine spray only in the evening. Pruning is unnecessary.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
