Sweetgum

[ click on any image below to see larger version ]


Family: Altingiaceae

Mid-Atlantic bloom time: April - May

Mid-Atlantic fruit ripe: August - September

The spiky fallen fruits ("gum balls") of Sweetgum are usually the first thing one encounters with this tree. They are hard and uncomfortable when stepped on with bare feet, and remain long into the next year. Sweetgum's leaves are characteristic with 5 palmate lobes (rarely 3 or 7 lobes), looking somewhat like 5-pointed stars, with slight serrations. In autumn, the leaves turn brilliant yellow and red unless killed off by an early frost while still green. Branches are often corky, having a winged look to them.

Flowers of Sweetgum are unisexual, with the male (staminate) flowers in separate terminal elongated clusters (racemes), and the round female (pistillate) clusters also on the end of the branches, hanging down.
