Clethra
Sweet pepperbush or summersweet is becoming popular again in our country. It is a medium-sized shrub flowering in summer.Rosea is one of the older varieties or selection of summersweet with deep pink buds and light pink flowers. They are formed in upright racemes and open in July and August. They have a lovely, sweet fragrance, hence its name. Oval leaves are deciduous, mid-green, upto 10 cm long, finely serrated and look like hydrangea leaves. For dense foliage it does not like being shaded by other, smaller companion plants very near. Pruning can be done in early spring, you can cut up to 30% of previous year’s growth.
Grow it in acid, fertile, humus-rich, moist but well-drained soil in full sun or partial shade. Fully hardy to -34°C or more (USDA zone 4).
