Explanation of
name: Genus named for Pierre Magnol, 1638-1715, botanist at Montpellier
(BA1, FNA). Grandiflora means large-flowered.
Natural range:
Southern U.S., including Florida. Indigenous to moist habitats, ravines,
hammocks, wooded dunes and mesic woods (FNA)
Recognition:
Tree with large, glossy, dark green leaves having rusty pubescence beneath.
Terminal bud large, encased in a cone-shaped pubescent stipule. Flowers
bowl-sized and bowl-shaped. White with numerous stamens and numerous pistils
(forming a cone at the center). Fruit made up of many separate units, each
opening to allow a red seed to dangle on a thread. Sweetbay Magnolia (M.
virginiana) has the leaves almost hairless and whitish on the undersides.
‘Little Gem’ is a dwarf cultivar popular in local landscaping.
Landscape uses:
Magnificent flowering specimen tree. According to UFST375, roots can extend 4X

replacement in Spring, messy at that time.
