Magnolia soulangeana - flori mari, parfumate D19

Magnolia x soulangeana , also known as the "tulip magnolia" or "saucer magnolia", is a hybrid ornamental shrub or tree in the family Magnoliaceae, noted for its large, showy flowers and elegant appearance. This hybrid, resulting from a cross between Magnolia denudata and Magnolia liliiflora , is one of the most popular magnolias grown in gardens due to its dramatic blooms and adaptability.

Flower appearance

• Shape : The flowers are large, cup- or tulip-shaped, with fleshy, layered petals, 10-20 cm in diameter. They open completely into a saucer shape (hence the name "saucer magnolia").
• Color : Varies in shades of pure white , pale pink and deep purple , with the inside of the petals often whiter and the outside more colorful, creating a bicolor effect. Some varieties (e.g. 'Lennei') have darker shades of purple.
• Fragrance : It exudes a delicate, floral fragrance , sometimes with citrus notes, which adds extra charm to the garden.
• Flowering period : It blooms in early spring, in March-April , before the leaves appear, providing an impressive visual spectacle. Flowering lasts 2-3 weeks, but can be affected by late frosts.

Growth characteristics

• Height : Grows as a large shrub or small tree, reaching 4-8 meters tall and 4-6 meters wide, with a round or spreading crown.
• Foliage : The leaves are oval, dark green , 10-15 cm long, with a glossy texture. They fall in autumn, sometimes turning yellow.
• Vigor : It has moderate growth, forming a branched structure, often with low branches, which give a picturesque appearance.

Growing conditions

• Exposure : Prefers full sun or light semi-shade , with protection from strong winds that can damage the flowers.
• Soil : It needs fertile, well-drained soil with a slightly acidic to neutral pH (5.5-7). Clay or loamy soils, rich in organic matter, are ideal.
• Watering : Requires regular watering, especially in the first years and during dry periods, but does not tolerate soggy soils.
• Pruning : Pruning is minimal, done after flowering (April-May) to remove dead branches or to shape the plant. Severe pruning can reduce future flowering.

Care and resistance

• Hardiness : It is hardy to temperatures down to -20°C to -25°C (USDA zones 4-9), but the flowers are sensitive to late spring frosts, which can brown the petals. In colder climates, planting in a sheltered spot is recommended.
• Fertilization : A balanced fertilizer applied in spring supports growth and flowering. Avoid excess nitrogen, which favors foliage over flowers.
• Pests and diseases : It can be affected by aphids, mealybugs or powdery mildew, but is generally resistant if it is well ventilated and not overwatered.

Magnolia x soulangeana is ideal as a solitary plant in gardens, lawns or parks, where its flowers can be admired in all their splendor. It also fits in small groups or as a background for other perennials. It combines beautifully with azaleas, rhododendrons or dwarf conifers, creating a harmonious landscape. Due to its size, it is suitable for medium to large spaces.

Origin

Magnolia x soulangeana was created in 1820 by Étienne Soulange-Bodin, a French cavalry officer and horticulturist, at his château in Fromont, France. The hybrid resulted from the cross between Magnolia denudata (originally from China, with white flowers) and Magnolia liliiflora (also from China, with purple flowers). Introduced into horticulture in the 19th century, it quickly became popular in Europe and North America due to its impressive flowers and adaptability. Over time, numerous cultivars have been developed (e.g. 'Alba', 'Lennei', 'Rustica Rubra'), each with variations in color and size.
