과명 Oleaceae (물푸레나무과) 속명 Chionanthus (이팝나무속) 전체학명 [정명] Chionanthus virginicus L. 추천명 미국이팝나무 이명 외국명 Old-man's-beard 추천명변경: 버지니아이팝나무 -> 미국이팝나무 Chionanthus virginicus (white fringetree) is a tree native to the savannas and lowlands of the southeastern United States, from New Jersey south to Florida, and west to Oklahoma and Texas.
Growth
It is a deciduous shrub or small tree growing to as much as 10 to 11 metres (33 to 36 ft) tall, though ordinarily less. The bark is scaly, brown tinged with red. The shoots are light green, downy at first, later becoming light brown or orange. The buds are light brown, ovate, acute, 3 millimetres (0.12 in) long. The leaves are opposite, simple, ovate or oblong, 7.5 to 20 centimetres (3.0 to 7.9 in) long and 2.5 to 10 centimetres (0.98 to 3.94 in) broad, with a petiole 2 centimetres (0.79 in) long, and an entire margin; they are hairless above, and finely downy below, particularly along the veins, and turn yellow in fall. The richly-scented flowers have a pure white, deeply four-lobed corolla, the lobes thread-like, 1.5 to 2.5 centimetres (0.59 to 0.98 in) long and 3 millimetres (0.12 in) broad; they are produced in drooping axillary panicles 10 to 25 centimetres (3.9 to 9.8 in) long when the leaves are half grown, in mid- to late May in New York City, earlier in the south.
It is usually dioecious, though occasional plants bear flowers of both sexes. The fruit is an ovoid dark blue to purple drupe 1.5 to 2 centimetres (0.59 to 0.79 in) long, containing a single seed (rarely two or three), mature in late summer to mid fall.
Etymology
The species name was originally cited by Linnaeus as Chionanthus virginica, treating the genus as feminine; however, under the provisions of the ICBN, the genus is correctly treated as masculine, giving the species ending as virginicus. Other English names occasionally used in the Appalachians include Grancy Gray Beard and Old Man's Beard.
Cultivation and uses
Although native in the southeastern United States, it is hardy in the north and is extensively planted in gardens, where specimens are often grown with multiple trunks. The white flowers are best seen from below. Fall color is a fine, clear yellow, a good contrast with viburnums and evergreens. It prefers a moist soil and a sheltered situation. It may be propagated by grafting on Ash (Fraxinus sp.). The wood is light brown, sapwood paler brown; heavy, hard, and close-grained.
