What Type of Tree Makes an Acorn? Only trees in the Quercus genus produce acorns. Watch a squirrel or chipmunk forage for food and no doubt a cache of acorns will appear. Acorns provide food for various wildlife, or they would otherwise litter the forest floor and rot since they are too heavy to disperse via wind.
Quick Answer. Acorns, the seeds of oak trees, fall off their parent trees when they mature, which typically occurs between September and early November in the United States. The exact time of maturation varies slightly with different types of oak trees. Maturation of an acorn takes six to 24 months, depending on species. The color of an acorn changes from green to dark brown as it matures. Acorns may also fall off trees if the branches are shaken. When the trees are plentiful, acorns are an essential food source for the local wildlife.
