Quercus marcocarpa, the bur oak, is the tree featuring the largest acorns of any North American oak species, notes the âNational Audubon Society Field Guide to Trees: Eastern Region.â In comparison to the fruits of other oaks, they are huge.
Oak trees grow from acorns that drop from the trees in early fall. Oak trees produce both male and female flowers on the tips of their uppermost branches, which are relatively unnoticed. Pollen from the male flower fertilizes the female ovary, which develops into an acorn. The petals and sepals of the ovary fuse to form the acorn's top, or cap. The acorn falls off the tree in late summer or early fall, and under the right conditions will germinate and grow into a new oak seedling.
