Chimonanthus praecox is also known as wintersweet. It’s the perfect name for a shrub with deliciously scented flowers that appear in June and July. The small, pale yellow, waxy blooms appear on bare stems and might appear insignificant. But they really do punch above their weight in fragrance terms. Wintersweet is a relatively slow-growing shrub, good for a medium-sized garden as it reaches a maximum height of 4m, and spreads to around 2.5m. Florists love wintersweet for cutting and adding to winter floral arrangements.
