Summary

This gem brightens up the garden border during a quiet time of the season. Clethra alnifolia is a multi-stemmed, suckering shrub that will grow 5-8’ high in full sun to part shade. It prefers moist to wet, acidic soils but is amazingly adaptable to dry conditions. Summer sweet clethra blooms during mid-summer with a profusion of white bottlebrush-like flowers that are very fragrant. This deciduous shrub has shiny, dark green leaves that turn an attractive yellow in fall. Plant Clethra alnifolia with other summer bloomers like Rhododendron prunifolium, Rubeckia fulgida ’Goldsturm’, Lobelia cardinalis and Actaea racemosa.
