Description

A slender tree twenty or thirty feet high; at the north a shrub of several thick, spreading stems. Commonly planted on lawns and parks. Ornamental. Roots are fibrous.[1]

The singular appearance of its snow white flowers which look like a fringe is the source of its common name. These flowers appear abundantly when the leaves are half grown and the foliage mass becomes a combination of soft green and pure white, which is most beautiful.[1]

  • Bark: Brown, tinged with red, scaly. Branchlets terete, light green, downy, at first; later they become light brown or orange color.
  • Wood: Light brown, sapwood paler brown; heavy, hard, close-grained.
  • Winter buds: Light brown, ovate, acute, one-eighth of an inch long. Outer scales fall when spring growth begins, inner scales enlarge with the growing shoot and become leaf-like, an inch or more in length.
  • Leaves: Opposite, simple, ovate or oblong, four to eight inches long, one to four inches broad, wedge-shaped at base, entire with undulate margins, acuminate, acute or rounded at apex. Feather-veined, midrib stout, primary veins conspicuous. They come out of the bud conduplicate, yellow green and shining above, downy beneath; when full grown are dark green above, pale below and smooth except the midrib and veins which are hairy. In autumn they turn a clear yellow and fall early. Petiole stout, hairy.
  • Flowers: May, June; when leaves are one-third grown. Perfect, white, slightly fragrant, borne in loose, downy, drooping, bracted panicles, four to six inches long, from lateral buds; peduncles three-flowered.
  • Calyx: Four-parted, small, smooth, persistent.
  • Corolla: An inch long, white, dotted on inner surface with purple spots, deeply divided into four, varying to five and six, long and narrow lobes barely united at base; conduplicate, valvate in bud.
  • Stamens: Two, inserted on the base of the corolla, extrorse, filaments short; anthers pale yellow, ovate, two-celled.
  • Pistil: Ovary superior, two-celled; style short; stigma fleshy, two-lobed.
  • Fruit: Drupe, borne in loose clusters, on which the bracts have become leaf-like. Oval or oblong, dark blue, glaucous, one-half to three-fourths of an inch long, surrounded at base by the persistent calyx and tipped with remnants of the style. Skin thick; flesh dry; stone thin.[1]

Distribution

Ranges from Pennsylvania to Florida, westward through the Gulf states to Texas, Arkansas, and Kansas.[1]

Cultivation

The Fringe-tree is one of the most beautiful of the ornamental shrubs of the United States and although a native of the south it is hardy at the north and is extensively planted. It prefers a moist soil and a sheltered situation and may be propagated by grafting on the ash.[1]

Medicinal uses

Chionanthus virginicus has a few medicinal uses. The dried roots and bark are used to treat skin inflammations. It can also be employed for all liver problems. Also used in gall-bladder inflammations. Reduces surger levels in urine. The crushed bark can be used in treatment of sores and wonds.
