No they don't. What kind of trees are coniferous? It means, cone bearing. So, the most familiar kind of cone on a tree is the pine cone. What kind of leaves do pine trees have? They have needles, very narrow leaves that do not drop off in the fall, but stay on all year. Some conifers, such as the Larch, drop their leaves in the Autumn, but they do not have large broad leaves.
