Magnolia grandiflora is a broadleaf evergreen tree that is noted for its attractive dark green leaves and its large, extremely fragrant flowers. Over time, it grows to 60-80’ tall with a pyramidal to rounded crown. This is the magnificent tree of the South. It is native to moist wooded areas in the southeastern United States from North Carolina to Florida and Texas. Leathery evergreen ovate to elliptic leaves (to 10” long) are glossy dark green above and variable pale green to gray-brown beneath. Fragrant white flowers (to 8-12” diameter) usually have six petals. Flowers bloom in late spring, with sparse continued flowering throughout the summer. Flowers give way to spherical cone-like fruiting clusters (to 3-5” long) that mature in late summer to early fall, releasing individual rose-red coated seeds suspended on slender threads at maturity.
Our selection is derived from the cultivar, 'Edith Bogue' and she is the hardiest of all the southern magnolias. Her leaves are glossy and the flowers are large, porcein-like and fragrant. We have compared it to Brakens Brown Beauty and D.D. Blanchard, and we prefer it in beauty, hardiness and stature.
From Wikipedia: "'Edith Bogue' was brought to the coastal plain of New Jersey from Florida in the 1920s. The original tree sent to Edith A. Bogue from Florida helped to establish cold-hardy specimens in the Middle Atlantic states from Delaware to coastal Connecticut, as well as the lower Midwest. Once established, 'Edith Bogue' has been known to have only minor spotting and margin burn on the leaf in temperatures as low as −5 °F (−21 °C). With a vigorous classic pyramidal shape, this cultivar grows to 35 ft with a 15-ft spread. The leaves are large and deep green, but lack the brown indumentum on their undersides which make other cultivars so distinctive."
There are no serious insect or disease problems. This is a beautiful specimen flowering tree for gardens and lawns.
