This old time favorite native plant for southern landscapes has been used for generations because of its seasonal beauty, hardiness, durability and resistance to disease and insect pests. Virginia Sweetspire has many notable characteristics - gorgeous white, slightly fragrant flowers that show up in late April to May and superb fall color.
It is tolerant of wet soils, yet amazingly it has very good drought tolerance. When placed in full sun the foliage gets denser and the flowers are more abundant.
Flowers are formed on the previous season's wood so we should always wait until after flowering to prune. In the fall, the leaves change to burgundy-purple which presents an attractive contrast to broadleaf evergreens in the landscape.
Plant them en masse for best effect - if given adequate sunlight and moisture they will supply many years of enjoyment.
You can find sweetspire in the Herb Garden, Boulder Garden, and other places throughout the Linnaeus Garden. (2015)
