Daphne, edgeworthia, and foam flower are my favorites..that I can manage to get to a bloom AND not get devoured. Lilac is a favorite but we don't have long enough / deep enough cold and roses are deer food. Also a subtle favorite that wafts around the garden..with the best spicy scent is caryopteris dark knight.
Who can resist the scent of the fringe tree...although short lived?
