Hello Christine, Thank you for your question. The cooperative breeding program between USDA and OSU in Corvallis has developed a number of thornless blackberry cultivars.  In the link below, you can find a list of many blackberry cultivars in the Pacific Northwest, as well as their traits (like thornless or not).
