This large, deciduous tree is located in Zones 1-6. It grows best in moist soil on mountainous slopes and bottomlands. Yellow poplar is commonly identified by its tulip-like flowers that emerge during springtime. There are also other identifying characteristics foresters can look for on their next nature walk. Here, we review the description, range, and uses of the yellow poplar tree. Description and Identification picture by la-ong / Moment / Getty Images The yellow poplar tree is also called tuliptree, tulip-poplar, white-poplar, and whitewood. It is fast-growing and typically reaches heights between 80-100 feet. The trunks become massive in old age and deeply furrowed with thick bark. The tree maintains a straight trunk and generally does not form double or multiple leaders. Yellow poplar has a unique leaf with four lobes separated by rounded notches. The fall color is gold to yellow and is more pronounced in the northern part of its range. The scented, tulip-like, greenish-yellow flowers appear in mid-spring but are not as ornamental as those of other flowering trees because they are far from view. Natural Range Yellow poplar has a vast range, growing in southern New England and west through southern Ontario and Michigan. They are found as south as Louisiana and in eastern to north-central Florida. The tree thrives in deep, well-drained soils that are rich in quality and located in forest coves and on lower mountain slopes. According to the Southern Research Station at the USDA, yellow poplar thrives best in the Ohio River valley and in the mountainous regions of North Carolina, Tennessee, Kentucky, and West Virginia. Silviculture and Management The U.S. Forest Service (USFS) notes that although it is a "rather large tree" the yellow poplar can be planted on residential streets as long as they are on very large lots with plenty of soil for root growth and if they are set back 10 to 15 feet. They also should not be planted in large numbers and are best for "lining commercial entrances with lots of soil space." While trees may be planted from containers, transplanting from a field nursery is best scheduled for spring. Plenty of water is needed for proper management. Because of summer drought conditions, yellow poplar may undergo premature defoliation. Common Pests and Diseases Larval mine of yellow-poplar weevil. Lacy L. Hyche / Auburn University / Bugwood.org Aphids can sometimes be an issue for yellow poplar trees. These insects suck the sap from trees and plants, and for yellow poplar, in particular, they may leave deposits of honeydew behind. The honeydew can lead to mold, and while this does not cause lethal damage, it can be difficult to deal with and treat. The USFS recommends horticultural oil sprays in the spring. Yellow poplars are also not immune to funguses that cause rot, as well as stem cankers. Cankerous trees tend to be unhealthy due to drought, competition, or other poor environmental conditions. Any branches found with these problems should be pruned. Another concern, leaf spots, are typically not serious enough to need chemical controls. However, if leaves have become heavily infected, it is too late to use chemical controls. The USFS recommended raking and getting rid of these infected leaves. They can be identified by their yellow spots. Uses The soft and light wood of the yellow poplar was hollowed out by early American settlers to use as canoes. Today's wood is used for furniture and pallets. Yellow poplar is also valued as a honey tree, a source of wildlife food, and a shade tree for large areas.
