The Prime-Ark Freedom Thornless Blackberry is a new variety of Blackberry from the Southern Living Plant Collection! The legends are true about the Prime-Ark Freedom. It’s thornless, it’s a Primocane (which means that it fruits on the first year’s growth), and it produces huge berries! The average Prime-Ark Freedom blackberry weighs about 9 grams, however, the largest recorded berry weighed 16 grams! This fruit is quite plentiful. Traditionally, fruit from the second year’s growth is slightly larger than fruit from the first year’s growth. These blackberries are quite tasty. They’re outstandingly flavorful but slightly less so than the delectably flavorful Osage Thornless Blackberry. Furthermore, they’re notably sweet but slightly less sweet than the decadently sweet Navaho Thornless Blackberry. Expect these berries to start ripening from mid to late summer.
This variety has an upright growth habit. Therefore, it doesn’t spread naturally. However, branches that touch the ground can sprout roots.
The Prime-Ark Freedom Thornless Blackberry matures from 5-6′ H x 5-6′ W. So you can look forward to some considerable harvests once it has reached maturity.
This Blackberry is perfect for the Southern U.S. due to its impressive heat and humidity tolerance.
