Laura Barnes began cultivating wintersweet at the Barnes Arboretum in 1933. A vigorous deciduous shrub reaching 10 to 15 feet tall, wintersweet features strongly scented solitary flowers that hang on the bare stems in winter. The exact timing of bloom is dependent on the weather each year. During early winter, wintersweet blossoms with a barrage of waxy butter- or sulfur-yellow flowers with maroon interiors. The flowers, which are beetle-pollinated, are delicate in appearance and arguably carry the best scent of any flower anywhere. As a gardener you have not lived until you’ve cozied up to wintersweet for a whiff!
