Deutzia

Deutzia is the perfect little shrub for covering large areas and suppressing weeds

Deutzia is a genus of about 60 species of flowering plants in the family Hydrangeaceae native to eastern and central Asia and Central America. Most are deciduous specimens, but a few subtropical species are evergreen. The deutzia shrubs are fairly new to gardens in the botanical world not actually seen in Europe till the 1830s. It was discovered not in the wild, but in cultivation in a Japanese nursery. Named in honor of Dutch plant hunting patron, Johann van der Deutz..

All deutzia should be pruned immediately after the flowers have finished as they flower on wood growths made in the previous growing season. If you prune them too late after flowering, then they will not have enough time to produce their new stems - which will of course be the flowering stems for the next year.
