Description
M. grandiflora is a perennial tree of the Magnoliaceae family native to North America and introduced to Puerto Rico.[1]
Distribution
It is difficult to determine the natural range of M. grandiflora. The pre-Columbian range was likely from southeastern North Carolina to peninsular Florida, then west to eastern Texas, staying mainly on the Coastal Plain. Now, due to naturalization and horticultural planting, its range has expanded northward and inland. It also grows in Puerto Rico.[2]
Ecology
Habitat
M. grandiflora is found in suburban woodlands, maritime forests, mesic Coastal Plain bluffs and flats, bottomlands, now also widely naturalized, spreading from cultivation into wet to mesic (and even dry) forests.[2] Specimens have been collected from the shores of freshwater springs, densely-wooded hammocks, sand dunes, mixed hardwood forests, wet bottomland hammocks, swamp borders, and lakeshores.[3]
Phenology
M. grandiflora flowers from April through July[4] and fruits from September through October.[2]
Fire ecology
M. grandiflora is fire resistant, but has a low fire tolerance;[1] despite this, populations have been known to persist through repeated annual burning.[5]
Herbivory and toxicology
Magnolia grandiflora has been observed to host ladybugs such as Harmonia axyridis (family Coccinellidae), plant bugs such as Lygus lineolaris (family Miridae), and assassin bugs such as Apiomerus crassipes (family Reduviidae).[6]
Diseases and parasites
A common beetle that can cause death at the tips of branches is the Xylosandrus campactus, an ambrosia beetle.[7]
