Enjoy extended harvests and effortless maintenance with Prime-Ark® Blackberry Plug Plants — a breakthrough everbearing, thornless variety that delivers two crops each year. Developed for both performance and ease of care, Prime-Ark produces fruit on both first-year (primocanes) and second-year (floricanes), offering an early summer crop followed by a generous fall harvest.

The berries are large, firm, and sweet with excellent shelf life, ideal for fresh snacking, baking, freezing, or selling at market. With thornless canes and hardy, vigorous growth, Prime-Ark is perfect for backyard gardeners and small orchard growers alike. Each 1-year-old plug plant ships dormant with an established root system for fast establishment and dependable yields.
