American sweetgum (Liquidambar styraciflua) is a woody deciduous tree that's often found in wet river bottoms and swamps, as well as on drier uplands. "It's noted for the star-like leaves and hard, spiked fruits with fall color that resemble embers of a fire," says Canney. "Regular care is essential, including regular watering, especially during periods of drought, and essential during the tree’s establishment phase."
