The official tree of Mississippi is the southern magnolia (Magnolia grandiflora), chosen for its oversized, lemon-scented flowers and evergreen foliage. Mississippi designated it the state tree in 1938, and the tree also lends its blossom to the state flower and its name to the "Magnolia State." The flowers routinely span 5–10 inches across, making them among the largest tree-borne blossoms in North America.
How Magnolia grandiflora Builds a Flower That Big
A southern magnolia blossom is a botanical throwback. The flower has no true petals or sepals; instead it carries 6–15 petal-like tepals, each 2–4 inches long and 1–2 inches wide, arranged in overlapping whorls around a cone-shaped receptacle. That receptacle bears dozens of stamens and pistils packed in a spiral, a primitive arrangement that predates the familiar stamen-and-pistil layout of most modern flowers.
Size comes from hydraulic investment, not just genetics. A single open bloom can transpire noticeably on a hot day, and the tree supplies it through a thick peduncle and a dense vascular network in the receptacle. The tepals are thick and fleshy, roughly 10 times the thickness of a cherry petal, which lets them hold shape for a day or two before browning.
Pollination is done by beetles, not bees. The flowers open in the morning, stay receptive for about 24–36 hours, and then close their tepals over the beetle visitors, trapping them overnight in a pollen-coated chamber. The next morning the tepals reopen and release the beetles. This beetle-trap mechanism is one of the most reliable field-identification behaviors of the species.
Fragrance is a chemical lure. The flowers release a mix of terpenoids and benzenoids, including linalool and methyl benzoate, at highest concentration in the evening. The scent travels far enough to draw beetles from a distance, and it is the reason magnolia blossoms are cut for indoor display despite their short vase life.
Quantified Context: Range, Size, and Timing
Southern magnolia is native to the coastal plain from southeastern North Carolina through Florida and west to eastern Texas, roughly USDA zones 7–10. Mature trees reach 60–80 feet tall with a spread of 30–50 feet, and trunks can exceed 3 feet in diameter. Growth is moderate, typically 1–2 feet per year in youth.
Flowering runs from late spring into summer, with the heaviest flush from May through June in the Deep South and scattered blooms into August. Individual flowers last 1–2 days on the tree. The fruit is a cone-like aggregate 3–5 inches long that ripens in fall and splits to release bright red seeds.

Bigleaf magnolia (Magnolia macrophylla) technically produces larger individual flowers, up to 14 inches, but it is not Mississippi's state tree and is uncommon in cultivation. The state designation belongs to M. grandiflora alone.
Timeline of the Designation and the Tree's Spread
| Year | Event |
|---|---|
| Pre-1700s | Indigenous peoples across the Southeast use magnolia wood and bark |
| 1730s | European cultivation begins; the species reaches British gardens |
| 1861 | Mississippi adopts the magnolia blossom as a symbol during the Civil War era |
| 1900 | Mississippi formally adopts the magnolia as state flower |
| 1938 | Mississippi legislature names southern magnolia the state tree |
| 1950s–present | Magnolia becomes a staple of Southern landscaping and campus plantings |
The 1938 tree designation came nearly four decades after the flower designation, a gap that trips up trivia answers. The flower came first; the tree followed. The nickname "Magnolia State" predates both official acts.
Edge Cases: Where the "Big Flower" Reputation Breaks Down
Cultivars vary widely in flower size and output. 'Little Gem' is a compact selection reaching 20–25 feet with flowers around 4–6 inches, smaller than the species. 'Bracken's Brown Beauty' and 'Edith Bogue' offer cold hardiness into zone 6 but produce standard-size blooms. A gardener expecting 10-inch flowers from a dwarf cultivar will be disappointed.
Northern plantings fail on cold, not on flower genetics. Below roughly 0°F, foliage and flower buds can be injured, and trees in zone 6 often survive as dieback shrubs rather than flowering specimens. The species also tolerates wet soils better than drought, an unusual trait among large landscape trees.
The "large flower" claim also has a timing trap. Most blooms open high in the canopy, so a mature tree's flowers are viewed from below at a distance that makes them look smaller than they are. Container-grown trees and lower branches give the best close-up views.
Misconceptions Worth Correcting
Mississippi has both a state flower and a state tree, and both are the magnolia. That double designation is uncommon and leads to the mistaken belief that only one exists.
The southern magnolia is not the same tree as the tuliptree (Liriodendron tulipifera), despite both being called "magnolia" family members. Tuliptree flowers are small, greenish-yellow, and cup-shaped, nothing like the magnolia's white saucers.
Leaves are not litter-free. Southern magnolia drops thick, leathery leaves year-round, and a mature tree can shed a substantial volume annually. The leaves decompose slowly, which matters for lawn health and drainage.
Red seeds are not edible for people. The fleshy red aril is dispersed by birds and mammals, but it offers no culinary value and should not be treated as forage.
Do not plant southern magnolia within 10 feet of a foundation or driveway; surface roots and dense shade cause damage. Do not expect blooms in the first 5–10 years from seed-grown trees; grafted or cutting-grown trees flower sooner. Do not site the tree in dry, exposed spots; drought stress in the first two summers is a leading cause of transplant failure. Do not confuse the evergreen southern magnolia with the smaller, deciduous sweetbay when shopping from a label photo.
Practical Actions for Growers and Identifiers
To identify the state tree in the field, look for evergreen leaves that are glossy dark green above and rusty-brown and felted beneath, 5–8 inches long. Confirm with the large white flower and the cone-like fruit. The rusty leaf underside is the single most reliable feature when flowers are absent.
For planting, choose a site with at least 6 hours of sun and room for a 40-foot spread. Dig a hole two to three times the root ball width but no deeper than the root ball. Water deeply once a week for the first two summers, roughly 10–15 gallons per session for a newly planted 6-foot tree.
For flower production, avoid heavy pruning in late winter, which removes the wood that would have carried spring buds. Fertilize lightly in early spring with a slow-release product; excess nitrogen pushes leaves at the expense of blooms.
For cut flowers, harvest in the morning just as tepals begin to unfurl, and recut stems underwater to extend vase life toward 2–3 days. Expect browning within 48 hours regardless of handling.
Limitations and What the Record Does Not Settle
State designation dates and legislative details vary in secondary sources, so the 1938 tree and 1900 flower dates should be checked against state archives for formal citation. Flower size ranges are horticultural observations, not controlled measurements, and vary with cultivar, age, and climate. Cold-hardiness claims differ by provenance, and a tree sold as zone 6 hardy may still lose flower buds in a severe winter. The beetle-pollination mechanism is well documented but the exact timing window varies with temperature and humidity.
