This familiar biennial features large 4″ clusters of 1/2″ flowers on 18-24″stems. Blooms in June and thereafter, in lots of different colors from white through deep red. Reseeds itself vigorously. The 1936 Vicks Seed catalog describes Sweet William as a favorite of old-time gardens, so it has been around a century or more and remains a personal favorite.
