Populus nigra, or lombardy poplar, is a non-native, fast-growing tree that is highly susceptible to Cytospora canker, a deadly fungal disease, making it unsuitable for most landscapes. This species is native to Europe, northwestern Africa, and western Asia. While it is tolerant of alkaline, flooding, clay, and dry soils and can serve as a windbreak, its short lifespan and vulnerability to disease make it a poor planting choice. It drops large leaves in the fall and produces cottony seed fluff, creating some mess and requiring frequent cleanup.
