Magnolia dodecapetala

Magnolia dodecapetala is a large evergreen tree in the magnolia family. Its native range lies in the Lesser Antilles. Bwapen mawon is one recorded common name. It grows in wet tropical forests with several canopy layers. These forests provide the hot, humid setting linked with this species. People harvest wild trees for timber and also grow it for ornament.

The tree forms a broad, rounded crown above a straight trunk. Sources list a height of about 115 feet [35 metres]. Some trees reach 131 feet [40 metres]. One account gives a spread of 98 feet [30 metres]. Long buttresses support the base of its cylindrical trunk. The trunk can reach about 3 feet [0.9 metres] across. It may lack branches for 39–59 feet [12–18 metres]. Growth is slow, according to Plants For A Future. The white flowers have a sweet scent. Its flowers, crown, and form give it landscape value.

In the wild, it grows at 1,378–2,461 feet [420–750 metres] above sea level. It does best in deep, rich soil in valleys. Reports also place it on level ground at middle elevations. The habitat account excludes ridges and slopes. Plants For A Future lists sand, loam, and clay as suitable soils. It calls for moist soil that drains well. The listed pH range runs from mildly acid to mildly alkaline. The tree needs an open site rather than shade. That source lists USDA zones 10–12. Detailed cultivation notes remain scarce.

The timber serves for furniture, floors, small boats, and fishing-canoe hulls. Its dark brown to black heartwood may show brown streaks. The pale sapwood ranges from white to light yellow. The wood has a fine texture and straight grain. Once dry, it lacks a marked smell or taste. Reports describe strong, hard wood that withstands shocks and other loads. It resists splitting and twisting and has some spring. Workers can shape it with ease, but nails and screws cause problems.

Reports disagree about how well the timber resists decay and insects. Some describe heartwood that insects leave alone. Others report damage from termites and fungi. These are timber reports, not a guide to garden pests. Neither supplied plant account identifies edible or medicinal uses. Both report no known hazards. That wording does not establish that any part is safe to eat.
