Hi, I see you are growing some of the tenderer teas - I was just about to plant a few myself. I am also in zone 6a/b, but it seems that people are not keen on growing them in this zone (even though it is listed as their hardiness). Can I ask you what your experience has been and which of the teas are better suited to 6? I have been thinking about the Bride and Maman Cochet. Thank you!
