Thank you Maurice. I should have checked AHS first.
I am still looking for my lemon yellow cultivar that appears and disappears. Likely it is descendant of citrina. I bought it labelled ''Lemon Yellow'' but appears to be unregistered. It smells divine so hope it is just still dormant. So far I have had a few deciduous cultivars survive and thrive here in subtropical Australia. We haven't had a frost in the last 2 years. A few registered as SEvs viz. MARCIA FAY, MAKING A SPLASH, wh is stunning, are completely deciduous which helps me battle against rust.
