Poplar trees are native to the Northern Hemisphere; they grow in the wild and are farm-raised too, and they belong to the larger class of deciduous trees. The most common varieties of poplar trees are aspen and cottonwood. Poplars reside in mixed deciduous and evergreen forests throughout the United States as well as in Canada and Mexico.
Poplar trees are deciduous, which means that they produce leaves and new growth on a seasonal basis instead of year round like evergreens and other conifers. These trees can withstand cold temperatures and heat spells but prefer to live in temperate zones with mild summers and winters and with partial shade. Poplar trees can be found lining city streets and town walkways and growing on residential properties. They are grown and cultivated in nurseries and commercial tree farms too; their wood is cut and used for timber and to make wooden goods such as bowls and spoons. Poplar trees also live in large, undisturbed tracts of forest and wilderness areas, serving as homes to birds and small mammals. Poplars may reach several stories in height and span up to 10 feet in diameter; they have smooth bark and small leaves that turn brilliant gold and orange colors in the fall, and they produce beautiful pink blossoms in the spring.
