I have been GROWER for more then 60 years. I used to travel all over the world and during that time I got various seeds and have developed my own hybrids for generations. I have varieties that can handle temps down to 1 (one) degrees Fahrenheit , I just harvested some "Blackberry Crush" one of my hybrids. Since it is the first year I am not sure has to how cold it can handle. It got down to 26 for hours (ohio) and it is fine. I pluck the buds, It was a cross between Strawberry Kush and my own Black Berry hybrid. The blackberry started coming up In December after Christmas last year as some years I have to replenish my seed stock. Five came up on their own from the seeds in the fall. Then it got -2 F and all but ONE died. It grew slowly until spring and then continued to get to about 6 feet and produced a lot. Found a good potting soil at Wmarts, called Natural Earth" something like that, has worm castings in it, suggest indoor growers try it, you will be amazed on how fast the plants will grow. Miracle Grow sucks, too much peat. My other cold varieties are "Arctic Tundra" good to about 9 degrees F.; The Black beery Crush was a big producer and grows very tall (the Blackberry normally grows to about 13 feet +/-. My Crush got to nearly 17 feet and has yielded more then a pound and a half DRY!
