Kadsura japonica 'Fukurin'

Kadsura is native from S Korea to Taiwan, which may account for the variable hardiness claims, Woodlanders calls 'Fukurin' zone 5 while many authorities list the species as zone 9. I’m convinced enough to put a plant on a south facing wall and microfoam it, my guess is zone six or seven which is do-able here with plenty of protection. We froze plants hard last fall and they dropped all their leaves, an excellent sign. 'Fukurin' is spectacular, with thick Hoya-like leaves broadly edged with cream. Don’t confuse the genus with Kudzu; Kadsura is a member of the Schisandraceae. The 2cm wide sulfur yellow flowers are followed by 3cm wide scarlet red pendulous berry like fruits dangling from 3-4cm stalks in the leaf axils.
