Thornless variety. Supposed to be best for cooler Houston metro areas. (I wonder just where that would be???). Since I live SW of Houston, ours were planted where they get a little shade.

First I have to disagree with the hardiness zone for this blackberry. We purchased ours from Stark Bros in Louisanna, MO and they are rated for zones 5-9. We planted them in April of 09 and they are already blooming and setting on berries. Don't know if this means they will bloom later here because we are further north or just because we planted them this spring. Seem to be vigorous growers (if the rabbits will stop trimming them for us). Finally completely caged them a week ago. Have great hopes for these as we have tried the thorned variety and that was awful.
