Populus canadensis, or Carolina poplar or Canada poplar, a hybrid between the native Populus deltoides and European Populus nigra, is a fast-growing tree ideal for sunny, moist sites, particularly near water. It tolerates a broad soil pH range and occasional flooding, making it perfect for quickly establishing a shaded canopy in naturalized areas. Trees often reach very large size in 50 years and then die over a short time period. Its brittle wood is vulnerable to storm breakage, and its roots can damage sidewalks and clog cracked sewer lines.
