Eons ago, magnolias ruled vast tracts of primeval forest in the Northern Hemisphere. This landmass was slowly ripped apart by geological forces and magnolia species were isolated by thousands of miles of ocean, Arctic ice sheets, and uplifting mountains. Species with close kinship came to rest in eastern North America and eastern Asia because of geology. Experts suggest that there may be in excess of 50 different species of magnolias in these two areas that share a common ancestry. To many, spring evokes visions of rhododendrons, clusters of colorful bulbs, or azaleas covered in bright blossoms.
Magnolias are just as dramatic and often provide softer, more refined color in the spring garden.
And the deliciously large, sweetly scented flowers of the southern magnolia have few rivals. Magnolias bloom spring through summer . While the magnolias at the Arboretum are largely concentrated in the Holly and Magnolia Collections, the Asian Collections are home to some of the most spectacular species. Here you can find Magnolia sieboldii, a shrubby tree located near the parking area and unusual because of its May blooms. Flowers of Magnolia zenii grace the slopes of China Valley in early spring.
