Outstanding Qualities Magnolia ‘Galaxy’ features fabulous, sweetly fragrant, dark reddish-purple blooms that can reach 8 to 10 inches in size. Unlike many magnolias, it has a narrow upright habit for many years, which makes it suitable for small gardens. Eventually, however, it will widen to about 25 feet. Magnolia ‘Galaxy’ begins blooming at an early age and flowers profusely as the tree matures. It blooms two to three weeks later than many other magnolias, thereby avoiding late spring frosts. It is stronger limbed than many magnolias and doesn’t break easily in harsh winter weather. It works well in either a woodland or mixed shrub border. Good companion plants include hellebores, spring-flowering bulbs, winter-flowering heaths, and broadleaf evergreens. ‘Galaxy’ was developed at the U.S. National Arboretum, where it resulted from a 1963 cross between M. liliiflora and M. sprengeri ‘Diva’.
Culture Magnolia ‘Galaxy’ needs even moisture and good drainage. Rich organic soils encourage vigorous growth. Plant in partial to full sun for best bloom. Garden gently under magnolias, for they have fleshy roots that can easily be damaged. The best approach for companions plants is to tuck in natural spreaders and let them flourish untouched.
Growing Habit Magnolia‘Galaxy’ has a ten-year height of 15 to 20 feet with a spread about half as wide. This magnolia can reach 30 to 40 feet high in time, with a spread of 25 feet.
Hardiness USDA zones 5 to 9
