About
Magnolia tripetala, commonly called umbrella magnolia or simply umbrella-tree, is a deciduous tree native to the eastern United States in the Appalachian Mountains, the Ozarks, and the Ouachita Mountains. The name "umbrella tree" derives from the fact that the large leaves are clustered at the tips of the branches forming an umbrella-shaped structure.
Where it grows
Umbrella magnolias have a native range from New York state to southern Florida. This range also expands as far west as Arkansas and parts of Oklahoma. It is located in deciduous forests of the Appalachian Mountains. Research has shown the species to be non-native to northern states such as in New England, and only being a recent arrival. This species has been cultivated in locations outsides its natural range, and has spread from these locations to nearby woodlands. Magnolia tripetala has been observed in forests outside its native range in multiple instances. Single individuals and small populations have been observed near areas where M. tripetala is in cultivation. Magnolia tripetala has been given the FACU wetland status, tending to prefer average to dry soil. The trees have low tolerance to drought and fire.
Uses
Magnolia tripetala contains a substance called ethyl acetate in its branches, and this substance displays nematicidal activity. This activity allows it to specifically resist Bursaphelenchus xylophilus, Panagrellus redivivus, and Caenorhabditis elegans.
