Sycamore maple (Acer pseudoplatanus) is a deciduous tree that typically grows 40 to 60 feet tall. It was imported from Europe and western Asia, and is used for landscaping in urban and suburban areas. It is mostly found growing in coastal communities.
It produces large numbers of seeds, and develops dense stands that shade out and outcompete native plants.
Mowing or hand pulling of seedlings and small saplings can be effective in preventing spread. Mature trees will re-sprout from the stump if not treated with a systemic herbicide. Girdling of mature trees may be effective, especially when girdles are treated with herbicide. Always read and follow the directions on the label when using herbicide.
