There are six fringe trees (Chionanthus virginicus) in the arboretum collection. There is a grouping of three individuals near the Fitness Center -- those finished blooming last week. Three others still have pretty, white flowers this week, and they are scattered about the arboretum. The photos below are from a 6-year-old tree, still quite small, growing in full sun on the hill that slopes down from the southwest corner of Mickle Hall.
Note: This species also goes by the name of grancy graybeard.
