A fruit tree catalog from California arrived in the mail with an amazing 
claim.

"Jujubes are high in Vitamin C and often referred to as Chinese Dates. 
Withstands wide ranging temperatures; from over 100° F to -28° F during 
dormancy. Requires minimal chill and hot summer sun to set fruit."

Their catalog offers five varieties. None are rated to take -28F, but all are 
rated Zone 5.

Anyone here try jujubes in cold climates?
