Noteworthy Characteristics
Liriodendron tulipifera, commonly called tulip tree or yellow poplar, is a large, stately, deciduous tree of eastern North America that typically grows 60-90' (less frequently to 150’) tall with a pyramidal to broad conical habit. Although widely planted throughout the state of Missouri, it is indigenous to rich woods in only a few counties in the far southeastern corner of the state. Trunks of mature trees may reach 4-6’ in diameter, usually rising column-like with an absence of lower branching. It is named and noted for its cup-shaped, tulip-like flowers that bloom in spring. Flowers are yellow with an orange band at the base of each petal. Although the flowers are 2” in length, they can go unnoticed on large trees because the flowers appear after the leaves are fully developed. Sometimes the flowers are first noticed when the attractive petals begin to fall below the tree. Flowers are followed by dry, scaly, oblong, cone-shaped brown fruits, each bearing numerous winged seeds. Four-lobed bright green leaves (to 8” across) turn golden yellow in fall. Wood is used inter alia for furniture, plywood, boatbuilding, paper pulp and general lumber. Native Americans made dugout canoes from tuliptree trunks. This is the state tree of Kentucky, Tennessee and Indiana.
Genus name comes from the Greek words leirion meaning a lily and dendron meaning a tree for the flowers.
Specific epithet means tulip bearing for the form of the flowers.
'Aurea-marginata', commonly sold under the trade name of MAJESTIC BEAUTY, is a cultivar that grows somewhat smaller than the species and features green leaves variegated with yellow margins. This form was introduced into commerce in 1986 by Monrovia Nurseries.
Problems
Watch for aphids and scale. Potential diseases include verticillium wilt, mold, mildew and canker. Large aphid infestations result in honeydew secretions on the leaves that provide the growing medium for sooty mold. Trees are fast-growing and somewhat weak wooded, making them susceptible to limb breakage in high winds or from ice/snow. Shallow root system limits the types of plants that may be grown within the drip line.
Uses
Very large shade or lawn tree for large landscapes. Generally not recommended as a street tree.
