| − | '''''Magnolia grandiflora''''', commonly known as the '''southern magnolia''' or '''bull bay''', is a tree of the family [[Magnoliaceae]] native to the [[Southeastern United States|southeastern]] United States, from coastal [[North Carolina]] to central [[Florida]], and west to [[East Texas]]. Reaching {{convert|27.5|m|ft|abbr=on}} in height, it is a large, striking evergreen tree, with large dark green leaves up to {{convert|20|cm|in|frac=4|abbr=on}} long and {{convert|12|cm|in|frac=4|abbr=on}} wide, and large, white, fragrant flowers up to {{convert|30|cm|in|abbr=on}} in diameter.

| − | Although endemic to the lowland [[subtropical]] forests on the Gulf and south Atlantic coastal plain, magnolia grandiflora is widely cultivated in warmer areas around the world. The timber is hard and heavy, and has been used commercially to make furniture, pallets, and veneer.

Many broadleaved evergreen trees are known as bays for their resemblance to the leaves of the red bay (''[[Persea borbonia]]''), with this species known as the bull bay for its huge size or alternatively because cattle have been reported eating its leaves.

| − | Southern magnolias are native to the [[Southeastern United States]], from coastal [[North Carolina]] south to central [[Florida]], and then west to East [[Texas]]. It is found on the edges of bodies of water and swamps, in association with sweetgum (''[[Liquidambar styraciflua]]''), water oak (''[[Quercus nigra]]''), and black tupelo (''[[Nyssa sylvatica]]'').

| |

| − | ''Magnolia grandiflora'' is a very popular ornamental tree throughout its native range in the coastal plain of the Gulf/South Atlantic states. Grown for its attractive, shiny green leaves and fragrant flowers, it has a long history in the southern United States. Many large and very old specimens can be found in the subtropical port cities such as [[Houston]], TX; [[New Orleans]], LA; [[Mobile, Alabama]]; [[Jacksonville]], FL; [[Savannah, GA]]; [[Charleston, SC]]; and [[Wilmington, NC]]. ''M. grandiflora'' is the state tree of Mississippi and the state flower of Louisiana.

Farther south, it is grown more widely in [[Delaware]], much of the [[Chesapeake Bay]] region in [[Maryland]], and much of eastern [[Virginia]].

[[Lumber]] from all three species is simply called magnolia, which is used in the construction of furniture, boxes, pallets, venetian blinds, sashes, and doors and used as veneers. Southern magnolia has yellowish-white [[sapwood (wood)|sapwood]] and light to dark brown [[heartwood]] tinted yellow or green. The usually straight-grained wood has uniform texture with closely spaced rings.

| |
| − | *'Bracken's Brown Beauty', developed by Ray Bracken of Easley, South Carolina, in the late 1960s, is a popular cultivar which has survived long-term in southern Ohio, West Virginia, New Jersey, and Long Island, NY. This cultivar grows in a dense and compact pattern, with narrow, medium-sized, glossy leaves. Flowers measure {{convert|5|-|6|in|cm|abbr=on}}.
| |
| − | *'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 {{convert|-5|°F|°C|abbr=on}}. 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.

| |
| − | *'Exmouth' was developed in the early 18th century by John Colliton in Devon. It is notable for its huge flowers, with up to 20 tepals, and vigorous growth.

| − | *'Little Gem', a dwarf cultivar, is grown in more moderate climates, roughly from Maryland and the Virginias southward. Originally developed in 1952 by Steed's Nursery in [[Candor, North Carolina]], it is a slower-growing form with a columnar shape which reaches around {{convert|4.25|m|ft|abbr=on}} high and {{convert|1.2|m|ft|abbr=on}} wide.
