Outstanding Qualities

This lovely open growing tree produces a profusion of lightly fragrant narrow petaled flowers in early spring. As the tree matures the flowering increases to a point where it looks like a billowy white cloud in flower. The roots are not aggressive and this tree casts open shade making it possible to garden under the canopy.

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.
