White Poplar

white poplarPopulus alba

Native to Europe and Asia, it was introduced to America for shade and ornamental plantings during Colonial times. A mature tree can reach 40 to 60 feet in height. The largest tree measured in the U.S. is in Michigan and is 86 feet tall, with a girth of 19 feet, 11 inches.

White poplar is an ecological threat to native plants, especially prairie communities. It outcompetes many native tree and shrub in mostly sunny areas, such as forest edges and fields, and interferes with the normal progress of natural community succession. It is an especially strong competitor because it can grow in a variety of soils, produce large seed crops, and re-sprouts easily in response to damage. It is rarely planted today.
