Gardeners' Notes:

Very productive and easy to grow here on edge of 8b/9a! Fast growing strong canes with loads of flowers and then loads of large yummy black fruit. I believe it is self fertile...
Tolerates ph 7.5 to 8, and still yields.
Somewhat drought tolerant, and also somewhat flood tolerant.

Can easily get 9+ feet tall if not pruned... But I recommend pruning new canes to 3.5 or 4 feet and side canes to 15 inches or so.

Only drawback to this variety is that it is in process of becoming patented.

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.

University of Arkansas release (plant patent applied for). Vigorous and productive with 1 inch berries on a thornfree plant. Ripens starting early June over 5 weeks. Zones 8A-8B.
