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 Notes
This magnolia is easy to grow. It flowers best when planted in full sun to light or open shade. It will thrive in a rich moist to well-drained soil, but will tolerate sand and clay if the drainage is adequate. Plant in an area that is protected from strong winds to help the flowers last their longest and keep the young foliage from being damaged. Regular summer water will allow the best flowering and healthiest growth, but well established plants can tolerate occasional watering during dry weather. 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. Pruning is best done after flowering.
