Hybrid poplars (Populus spp.) are among the fastest-growing trees in North America and well suited for certain site conditions. Many poplar hybrids are not desirable in urban landscapes because of disease (leaf spot defoliation) and their ragged appearance. Still, these hybrids are of major importance in providing wood products and assisting in soil stabilization.
Hybrid poplar is a "biologically manipulated" tree resulting from the combining, either naturally or artificially, of various poplar species into a "hybrid" of those species. These hybrids are developed primarily for quick growth important in establishing wind breaks, reclaiming erodible, stripped or polluted land and fiber for paper.
