Bark is soft-textured and bears a mottled pattern of dark and light. Leaves are star-shaped. Outer arms of the leaf are shorter than middle arms. Leaf length varies from four to nine inches. Leaf color is green in spring and summer.
Seasonal changes cause leaves to turn brown and drop off in autumn.
Distinctive seedpods appear by winter. These pods are spiked, golf-ball sized spheres. Each sphere is composed of densely packed seeds that appear as brown fluff when taken apart. The seedpods form in clusters of three to seven per stem. Sycamore Trees can be found in low-land areas along many of Dublin's creeks.
