Buttonbush
The Buttonbush, Cephalanthus occidentalis, is a rounded, 6 to 8 feet tall and occasionally reaqching 10 to 12 feet tall shrub. It is very open, almost gangly in habit. The late emerging foliage leaves the shrub almost dead looking until late spring. Flowers are creamy-white, on spherical heads, 1 to 1 1/4 inches long, blooming in late summer. The fruit is a nutlet that persists through winter. It prefers moist situations, not dry tolerant, and best used for naturalizing in wet areas. Native from New Brunswick to Florida, west to Minnesota, Oklahoma and southern New Mexico, Arizona, California, into Mexico and Cuba. ... additional info
Mock Orange - Sweet This name is probably derived from the fragrant white flowers resembling orange flowers that some species and cultivars of mock oranges have. Flowers are single, semi-double, or double and they vary in size. The bloom period is quite short, normally not more than 7 to 10 days. The summer foliage is dark green and quite free of pest and disease problems. There is no color change in the fall. It is possible that most mock oranges will suffer from occasional tip kill in zone 4 and quite often in zone 3.
