Meet one of the sweetest blackberry cultivar in the world! It is Ponca blackberry.
Ponca (Sweet-Ark Ponca) offers the top of flavor from one of the world’s leading public blackberry breeding programs. Ponca was selected by John R. Clark, and this cultivar is the twentieth blackberry from the fruit breeding program of the division’s Arkansas Agricultural Experiment Station.
Ponca is floricane-fruiting medium-sized thornless blackberry cultivar. Bushes are moderately vigorous and very prolific. Plants are low in height, about 1,5 m when properly tipping. Primocanes and floricanes are erect in growth habit. Berries and flower clusters are medium-large, cymose, and are mostly borne on the periphery of the plant canopy, providing easy access to harvest.
The canes can be trained to a self-supporting hedgerow although it is beneficial to use a trellis with supporting wires to prevent canes from falling over due to wind or heavy fruit loads.
The bloom period of the Ponca cultivar begins in the last week of April. Flower fertility is high and clusters are well filled. Flowers are big (about 40 mm in diameter), have white color. Berries ripen in the first week of June. The average floricane fruiting period is 55 days. Fruit yield on floricanes averages 5.8 kg per plant.
Average berry weight is about 6 g, slightly larger than Osage and nearly the same as Caddo. The fruit is round, slightly oblong in shape and glossy with a uniform black finish. Size is maintained well throughout the entire harvest season. Ponca cultivar exhibits excellent fruit fertility with full drupelet set.
The fresh fruit rates very well in flavor and is a noteworthy attribute of the cultivar and is comparable to Osage and Caddo. Consistent flavor was noted at repeated observations of fruit of this cultivar over the years of evaluation including after rain events that can reduce flavor and overall fruit quality. The flavor is sweet and sub-acid.
Storage potential of fresh fruit of the new cultivar is good and overall comparable to Osage and Caddo, berries are very firm.
Ponca is disease-resistant. Plants and fruit have shown no evidence of anthracnose and no evidence of susceptibility to orange rust. Plants have shown slight susceptibility to cane and leaf rust.
Winter hardiness has been comparable to Ouachita and has shown very little injury to a low of minus 17 С.

Prime-Ark Traveler 6.97 29x23 9.50 0.67 15.85

A-2491T 9.70 37x23 10.97 0.97 13.49

On the basis of Threlfall et al.’s (2016) findings on ideal composition parameters for fresh-market blackberries and according to market research, made in 2020 by Threlfall and John Clark et al.’s, Ponca have the most ideal composition of the cultivars evaluated, with a 12.83 soluble solids/titratable acidity ratio, 10.40% soluble solids, and 0.82% titratable acidity.

Review from [DEAN FAMILY ACRES]

We plant a row of blackberries on our 5 acres in SC Zone 8a. Ouachita, Ponca, Prime Ark-Freedom, Prime Ark-Traveler
A dream that has grown for generations. Our families have farmed or gardened in SC since the 1700’s. Dean Family Acres was established in 2013 and expanded in 2016, we strive to be “Real People, Real Homesteading.” We are on 5 acres in the Upstate of SC, zone 8a where we garden, feed chickens, cats, dogs, rabbits and Boer meat goats. We also enjoy landscaping projects and trips off the farm with our family of 6. Thanks for following our journey as we post a new video every Sunday.

Review from [ZENDOG]

I found a few Ponca on one of my first year plants today. I planted these in a row, but also put in a bunch of determinate paste tomatoes, peppers and some cucamelons between them that have now grown up so it is crowded and a bit hard to see all of the Ponca’s growth. I’ll let the Poncas have all the space next year, but thought they could share this year while they’re small. These tasted very good, but not quite as sweet as I had hoped, maybe from being shaded by the other plants. But the flavor was definitely a bit richer or fuller than other thornless I’ve tasted. I look forward to seeing what they do next year.

Review from [WOLFMANJACK]

The Ponca blackberries I planted in the spring are coming along nicely. A few of the plants flowered on the old growth bareroot stalk. I had a nice big juicy one that was to be ready today. Unfortunately when I got home from work it seems one of the local birds needed it more than me. There was a runt of a berry on the same bush that was black as well that the birds so graciously left me. I was not expecting much but to my delight the berry was very sweet with a very slight twang at the end. It was only one so not much of a sample size but I’m optimistic these plants will be winners next year. My sweetie pies have been getting destroyed by the birds and squirrels even with netting up. It’s so frustrating. If it’s war they want, it shall be war they get.

Review from [TEXASPREPPER2]

THERE IS A NEW BLACKBERRY VARIETY...! And it looks like it's going to be one of the BEST EVER.
Take a trip with me to Bob Wells Nursery at Sorelle Farms to get some new PONCA blackberries!
I think this is going to be a great new variety for the Homesteader/Backyard Gardener.
