It also is short-lived without very good drainage. All daphnes need perfect drainage or their roots will rot or freeze. Another type is Burkwood's daphne, a hybrid. There are several forms. One called Carol Mackie' is variegated.
Daphnes do have drawbacks.
The bloom period can be cut short by cold snaps that send temperatures into the teens or low 20s. Foliage is often burned by wind on sunny days when temperatures are below freezing. My daphnes receive little care. I do not fertilize them. I water twice a week.
