September Beauty summersweet is derived from a deciduous shrub native to the eastern US. 'September Beauty' has prolific fragrant white flowers that appear later in summer than most other summersweet clethras. The flowers attract butterflies and hummingbirds, along with other insects and birds. The flowers are produced on vertical flower spikes about 6 inches long that protrude from the dark green foliage.

'September Beauty' is a medium height shrub growing slowly to about 6 feet high and 5 feet wide and is suitable for borders, screens or as a specimen plant. Summersweet is tolerant of a range of garden conditions including shade, damp soils and clay and it flowers on new wood, so prune in late winter. Because it can tolerate shade it is also useful as an understory planting as long as the soil is kept moist, especially when establishing. It will sucker so unless a natural appearance is desired the suckers should be removed.
