Ziziphus jijuba - Chinese Date
Has anyone tried growing "jijube" aka "Chinese Date" in zone 5? I always see them spec'd at zone 6 and higher, yet from what I've read they are hardy to -20 and possibly even to -30 if fully dormant.
Is anyone growing them and if so do you have any idea how hardy they might be in zone 5b (kansas city)?
Thanks in advance for any information you can provide!
