The Prime-Ark® Blackberry is the first-ever thornless, primocane-fruiting (produces on both new and old wood) blackberry. This breakthrough variety produces exceptional fruit size with outstanding flavor, all on disease-resistant canes that thrive in heat and humidity. This heavy-yielding, blackberry vine will produce loads of delicious fruit from late August until fall (blooms in spring). It's the first of its kind, offering both early summer and fall harvests on the same plant and is part of the Prime-Ark® line of blackberries. Self-pollinating. The overall width and height of this variety is 4-6ft both tall and wide.

Full sun aspect or shade only early and late in the day. An area where the canes can multiply and spread without bothering other plants. As the plant grows, control suckers (cut back): either mow all canes to the ground in late fall/winter for a large fall crop, or prune only fruited (second-year) canes after spring harvest to get both summer and fall crops, leaving new (first-year) canes for fall fruit. Best grown in zones 5-9.

Considered non-toxic, however, the plant's leaves and stems can cause digestive upset if consumed in large quantities due to their high fiber content.

Considered moderately deer resistant.
