About the Sweet-Ark™ Ponca Blackberry Plant

A new, sweet cultivar for blackberry lovers! This recent release by the University of Arkansas, Sweet-Ark™ `Ponca` is a thornless, erect variety that is sure to impress the home gardener. The Sweet-Ark Blackberry bears some of the sweetest and most flavorful berries to come out of the program.

Blooming in April and setting fruit by June, this is an early-season variety. This summer-bearing blackberry plant is known for its high yields of fruit that maintain quality long after harvest. Picking the fruit is easy with thornless and erect canes. The firm, sub-acid berries are perfect for fresh eating, canning, and making naturally sweet jellies and jams. Sweet-Ark™ Ponca is the sweetest cultivar released to date.

Growing Sweet-Ark™ Ponca Blackberries

Sweet-Ark™ plants have been shown to stay in excellent health. Plant in a place with sun and well-drained soil. We recommend a soil pH level of 6.5 – 6.8 for blackberry plants. Trellising is not required for this erect blackberry plant. Tip plants back after harvest and prune again in early spring for best results.
