First of Its Kind
The Prime-Ark® Blackberry (Rubus fruticosus 'APF-153T' PPAF) is the first-ever thornless, primocane-fruiting blackberry. This breakthrough variety produces exceptional fruit size with outstanding flavor, all on disease-resistant canes that thrive in heat and humidity.

Early Fruiting
Prime-Ark® begins fruiting early in the season, and in regions with a suitable climate, it may produce a second harvest in the fall, extending your picking season. Its thornless canes make harvesting easy and enjoyable, and the plant reaches a mature height of 5 to 6 feet. It is hardy in USDA Zones 5 – 9. PPAF (Plant Patent Applied For).
