What kind of leaf does a poplar tree have?

Poplar trees typically have broad, lobed leaves that are triangular or heart-shaped with finely serrated edges. The leaves are often glossy green on the upper side and paler underneath. They can vary in size depending on the species, but generally, they are large and can range from 3 to 6 inches in length. In autumn, poplar leaves often turn vibrant shades of yellow.
