Corylopsis gotoana. Dirr mentions that there were 33 named species of Corylopsis. So it goes without saying that one will find many disagreements as to proper identification. But this is a new clone of this species which I just acquired and it is stunning! The first picture is of one year old 2 quart containers. The second year one will be blown away with the amount of flowers. Corylopsis need filtered sun in the Southeast, but with adequate moisture they will tolerate full sun. We haven't had deer problems with this genus even with susceptible plants nearby. Being in the Witchhazel family, it is an early spring bloomer, just behind Edgeworthias here in zone 8. The last picture is compliments of John Grimshaw.
