Three strains of tulip-poplar (Liriodendron tulipifera L.) were planted in 13 plots in the spring of 1973 and in one plot in the spring of 1975 in four of the climatic zones of southern Ontario. The study was designed to evaluate their hardiness north of its natural range in Ontario. Initial results after five growing seasons indicate that tulip-poplar can be safely planted north of its natural range in climatic zone D providing it is planted in woodlot openings where there is protection from early fall frosts.
