Chionanthus virginica (Snow Flower, or Fringe Tree) is a 

 native of North America, whence it was introduced in 1796. 

 It delights in a moist loam and a shady situation, and its fragrant, 

 pure white flowers, with long, narrow petals, are borne in pendent

 may be grafted on the Common Ash in March in the open 

 air, or raised from imported seed. It is useful for forcing.
