5 summer-flowering magnolias
for an exotic and fragrant atmosphere
Contents
With their white, pink, or purple flowers, delicately scented, magnolias are trees with an elegant silhouette and fragrance. Varying in size, they bring a graceful and exotic touch to a garden or terrace. There are two types of magnolias: those that bloom in spring and most often have deciduous foliage, and those that flower in summer with generally evergreen leaves. Hardy and easy to grow, Magnolia prefers to be planted in rich, cool soil or substrate, exposed to sun or partial shade, and sheltered from the wind. From the most well-known, which is the Magnolia grandiflora or large-flowered magnolia, to the more obscure, discover our selection of summer-flowering magnolias to inspire you.
Magnolia grandiflora 'Galissonière', a reliable choice
The Magnolia grandiflora ‘Galissonière’ is a variety of the famous Magnolia grandiflora, which is a reliable choice. This tree, with its rounded habit, rewards you with large flowers reminiscent of big white tulips from June to September. They exude a delightful and intense orange blossom fragrance. Slow-growing, the Magnolia grandiflora ‘Galissonière’ can reach a height of 10 to 15 metres at ripeness and is hardy down to –15°C. Its evergreen foliage is glossy green on top and matte bronze underneath. After flowering, conical, reddish fruits appear. This magnolia prefers to be planted in rich, cool, even moist soil in summer, and enjoys light sun or partial shade, sheltered from winds.
The Magnolia grandiflora ‘Galissonière’ is stunning and can stand alone in a garden. If you wish to pair it with other trees rather than plant it in isolation, you can choose companions such as other magnolias, like the Magnolia soulangeana, which is also well-known. This combination will allow you to enjoy a staggered flowering, with the Magnolia soulangeana blooming earlier, in spring, from April to May.

Magnolias: planting, pruning and careMagnolia sieboldii 'Colossus', a subtle citrus fragrance
The Magnolia sieboldii ‘Colossus’ is an improved variety of Siebold’s Magnolia. It is more suited to sunny conditions, flowers at a younger age, and grows faster. Reaching 8 metres in height at ripeness, this tree produces drooping, semi-double to double flowers that appear against medium green, deciduous foliage. The white flowers bloom from May to July in the form of flared bells measuring 15 cm in diameter and composed of 10 to 15 petals. The flowers feature beautiful purple-pink stamens with a light citrus fragrance. In autumn, large fruits appear and turn pink, while the foliage turns yellow before falling. Hardy down to –15°C, Magnolia sieboldii ‘Colossus’ prefers fresh, light, humus-bearing soil, as it is sensitive to lime.
In your garden, plant it in full sun or partial shade and accompany it with flowering dogwoods or sweetshrub to enhance the floral and exotic atmosphere. You can also plant it in isolation if you wish to showcase it entirely and ensure it is the focal point.

The Magnolia brooklinensis 'Eva Maria', with its changing coloured flowers
The Magnolia brooklinensis ‘Eva Maria’ offers a flowering display with subtle hues from May to June. Its large flowers resemble tulips standing upright and bloom from green buds tinged with violet. Even more astonishing, the petals change colour as they flower. From honey-washed magenta pink, they shift to a soft orange infused with green. The petals are waxy and thick, and the flowers open in the form of wide cups revealing orange stamens. The green foliage with silver undersides serves as a backdrop and is deciduous. The Magnolia brooklinensis ‘Eva Maria’ forms a rounded, ramified bush reaching a height of 3 metres at ripeness, making it a good choice for a small garden.
You can plant it alone on a lawn or in a bed complemented by a Japanese maple, a Hibiscus syriacus, a Prunus x subhirtella ‘Autumnalis’, or even a Cornus kousa ‘Satomi’. It can also be paired with other ericaceous plants such as rhododendrons, camellias, or heathers.
