Outstanding Qualities

Before the leaves appear in early spring large, fragrant, goblet-shaped flowers open with deep rose-pink exteriors and, as the blooms mature, pure white is revealed on the inside producing a lovely, almost bi-color appearance. The form of this hybrid magnolia is rounded, being almost as wide as tall with chubby, emerald green leaves in spring and summer.

Culture Notes
Plant in full sun for the best flowering, although light or open shade is acceptable. The soil should well-drained and a rich loamy type will provide for a healthy plant. Sandy soil is okay, but organic matter should be added and potentially more water when dry. Will tolerate clay soil, but must be well-draining. A location that is protected from strong winds will help keep the flowers and, later, the young leaves from being damaged. Magnolias require watering at least once a week during dry periods, although mature plants may tolerate 10 to 14 days between water cycles. Magnolias have fleshy roots that can easily be damaged so limit extensive gardening under established trees. Little pruning is required other than removing dead and broken limbs or poorly formed limbs; although one can prune for a somewhat more upright form, if desired. Pruning after flowering.
Geek Notes
Magnolia × soulangeana is a hybrid between M. denudata and M. liliiflora, both native to China. French Royal Institute Director Chevalier Etienne Soulange-Bodin first made the cross of the two species magnolias in the early 1800's, then selections were subsequently made after that. 'Alexandrina' was introduced around 1831 in France.
