Overcup oak is fairly easy to identify. The acorns are almost completely covered by their knobby cups. The leaves have long, narrow lobes and wide sinuses. In Missouri, it grows naturally only in wet forests along the Mississippi and Meramec rivers.

Autumn olive can be found all over the state, since it was planted widely with the best of intentions. Despite its “pros,” this shrub has proven to be very invasive. It threatens native ecosystems and should not be planted.

White mulberry was introduced from Asia for its berries and as fodder for an attempted silkworm industry. Birds have helped spread white mulberry so much that in many places it is more common than our native red mulberry.
