Magnolia 'Susan' - flori mari, parfumate

Magnolia 'Susan' is a hybrid ornamental shrub from the Magnoliaceae family, renowned for its large, fragrant flowers and its compact size, making it ideal for small gardens or urban spaces. This hybrid belongs to the "Little Girl" series, a group of magnolias developed in the USA, resulting from the crossing of Magnolia liliiflora 'Nigra' and Magnolia stellata 'Rosea'. 'Susan' stands out for its purple flowers and good frost resistance.

Flower Appearance

• Shape: The flowers are large, cup- or tulip-shaped, with 6-9 fleshy petals that open gradually, forming a semi-open flower. The flower diameter is about 10-15 cm.
• Color: The petals are a deep purple-pink on the outside, especially at the base, and paler, almost white, on the inside, creating an attractive two-tone effect. The buds are dark purple before opening.
• Scent: It gives off a sweet, floral fragrance with subtle notes, enriching the visual blooming experience.
• Blooming period: Blooms early spring, in March-April, usually before or during leaf emergence. The blooming lasts 2-3 weeks and is less sensitive to late frosts than other magnolias, due to the influence of Magnolia stellata.

Growth Features

• Height: Grows as a compact shrub or small tree, reaching 2.5-4 meters tall and 2-3 meters wide, with a round, dense crown.
• Foliage: The leaves are oval, dark green, 8-12 cm long, with a smooth texture. They fall in autumn, sometimes turning yellowish.
• Vigor: Has slow to moderate growth, forming a compact branched structure suitable for limited spaces.

Growing Conditions

• Exposure: Prefers full sun or light partial shade, with protection from strong winds that can damage the flowers.
• Soil: Needs fertile, well-drained soil, with a slightly acidic to neutral pH (5.5-7). Loamy or clay soils rich in organic matter are ideal.
• Watering: Requires regular watering, especially in the first years and during dry spells, but does not tolerate waterlogged soil.
• Pruning: Minimal pruning is done after flowering (April-May) to remove dead branches or shape the form. Heavy pruning can reduce future blooming.

Care and Hardiness

• Hardiness: Resistant to temperatures down to -25°C to -30°C (USDA zones 4-8), suitable for temperate climates, including Romania. The flowers are more resistant to late frosts than those of Magnolia x soulangeana, thanks to the heritage from Magnolia stellata.
• Fertilizing: A balanced fertilizer applied in spring supports growth and flowering. Avoid excess nitrogen, which favors leaves over flowers.
• Pests and diseases: Resistant to most problems but can be affected by scale insects, aphids, or powdery mildew in damp conditions; good ventilation prevents these issues.

Magnolia 'Susan' is ideal as a solitary plant in small gardens, lawns, or yards due to its compact size. It also fits well in mixed borders, groups, or as a backdrop for shorter perennials such as tulips, daffodils, or hydrangeas. The purple flowers combine beautifully with plants with silvery foliage or dwarf conifers. It is also suitable for large containers on terraces if proper drainage is ensured.

Origin

Magnolia 'Susan' was developed in the United States in the 1950s by Francis De Vos and William Kosar, horticulturists at the U.S. National Arboretum in Washington, D.C. It is part of the "Little Girl" series, which includes eight hybrids (e.g., 'Ann', 'Betty', 'Jane') created by crossing Magnolia liliiflora 'Nigra' (with purple flowers) and Magnolia stellata 'Rosea' (with pink-white flowers). The goal was to obtain compact magnolias with abundant flowering and increased hardiness, suitable for smaller gardens. 'Susan' was officially introduced in 1955-1956 and quickly gained popularity due to its vibrant flowers and practical stature.

Magnolia 'Susan' impresses with its purple-pink, fragrant flowers and compact size, making it an excellent choice for small gardens or urban spaces. With good frost resistance and minimal care, this magnolia from the "Little Girl" series offers a memorable spring floral display, bringing elegance and color to any landscape.
