Magnolia (Magnolia) – spectacular-flowering tree – 12 cm pot – height 30 cm

Yes, Magnolia grandiflora is considered hardy in most regions of France. It can withstand temperatures down to' -15°C once well established in the ground, in well-drained soil and a sheltered location. In regions with harsh winters (mountainous areas, North-East), it is recommended to protect the base with a thick mulch of dead leaves or b'ark, and t'o avoid exposure to icy northerly winds.

Unlike Magnolia stellata or Magnolia soulangeana, which bloom in spring before their leaves appear, Magnolia grandifloraMagnolia grandiflora) is one of the few magnolias that blooms in midsummer, from June to September depending on the climate and exposure. Its flowers are very large, reaching 20 to 30 cm in diameter on mature plants, pure creamy white with a golden-yellow stamen core. They give off an intense and sweet fragrance, both vanilla and lemon scented, noticeable from several meters away.

Yes, Magnolia grandiflora grows very well in a container on a sunny balcony or terrace, especially when it is young and its growth is still contained. Choose a large pot of at least 40 to 50 cm in diameter, with good drainage at the bottom, and use a mixture of quality potting soil, ericaceous soil, and sand to ensure a well-draining, slightly acidic substrate. In a pot, 'watering must be more regular than 'in the ground, as the substrate dries out faster. Apply a special fertilizer for flowering plants or shrubs starting in spring, about every three weeks.

Magnolia grandiflora prefers sunny to partially shaded positions, with protection from prevailing cold winds. A spot against a south or southwest wall, which radiates stored heat, is ideal for encouraging and prolonging summer flowering. As for the soil, this species appreciates cool, deep, well-drained, slightly acidic to neutral soils, rich in organic matter. It does not tolerate excessive lime, which causes chlorosis (yellowing of the leaves).

The growth of the Magnolia grandiflora (Magnolia grandiflora) is known to be slow, making it a long-term plant, particularly suited to small gardens and collector's plantings. In its early years, the plant focuses its energy on developing its root system. At maturity, depending on the variety and conditions, it can form a large shrub or a small tree measuring 6 to 10 meters in height when planted in the ground, with a conical to spreading habit. In regions with cold winters, its size often remains more modest.

Magnolia grandiflora does not tolerate severe pruning well and recovers with difficulty from major cuts to old wood. The g'eneral rule is to prune as little as possible and only when n'ecessary. It is best to prune at the end of w'inter, before the growing season begins, or just after summer flowering to remove faded flowers and any crossing branches. Only remove dead wood, damaged branches, or those that detract from the overall shape.

Magnolia grandiflora pairs remarkably well with 'other summer-flowering or ornamental foliage plants. For an elegant border, pair it with hydrangeas (Hydrangea), whose large late-'summer blooms echo its white flowers. Ornamental grasses, such as miscanthus or stipa, add movement and lightness around its base. Perennials like agapanthus or hostas can fill the ground around the base while ensuring visual continuity.
