Daphne sericea is one of the few species that bring a reliable re-bloom into a hybrid, like in D. susannae. The species by itself makes a great and easy to grow garden plant, with dark evergreen foliage and lots of very fragrant flowers. The main flush occurs in mid-spring and after a short break they'll usually bloom throughout summer into fall. Possibly hardy to USDA zone 6.
We’ve acquired D. sericea from 3 different places, one denoted as “compact form”, one as from Crete (this one at hand) and one without a designation. For the last 4-5 years, we were not able to detect the slightest difference.
