Origin: 'Ponca', also known as Sweet-Ark® Ponca™, is a new thornless, erect blackberry cultivar developed at the University of Arkansas by Dr. John R. Clark. It was released in 2019. It originated from a hand-pollinated cross of 'Ark. 2406' and 'Ark. 2253T'. It was selected for its exceptional sweetness, early ripening, and good postharvest handling potential.
Patent Status: 'Ponca' is protected by U.S. Plant Patent PP33,330, granted on 2021-08-10 to University of Arkansas at Little Rock until it expires on
2040-05-21. This plant patent grants the breeder exclusive rights to asexually reproduce the plant. Unauthorized propagation or sale of the cultivar is prohibited during the term of the patent.
Berry Production: Produces medium-sized, very firm, glossy black berries with a remarkably sweet, sub-acid flavor and an attractive aromatic component. It is considered the sweetest blackberry cultivar released by the University of Arkansas to date, with soluble solids often exceeding 10% and sometimes reaching 13%. It is a high-yielding variety with consistent production.
Ripening Time: 'Ponca' is an early-season ripening blackberry, maturing around the same time as 'Natchez', providing an early option for growers and home gardeners. It is a floricane-fruiting variety.
Plant Size and Appearance: 'Ponca' has an erect and compact growth habit with thornless canes, making harvesting easy. The canes have shortened internodes. Mature plants typically reach 4-6 feet in height and 3-4 feet in width. Primocanes emerge above the fruiting canopy, which simplifies tipping management.
Flowers: Produces typical white blackberry flowers in the spring on the previous year's canes (floricanes). It is self-pollinating.
Hardiness: Generally hardy in USDA Zones 5 through 9. It exhibits good winter hardiness, comparable to 'Ouachita', with limited winter injury reported down to 1°F (-17°C). It also shows good secondary bud crop potential following cold injury.
Pollination: 'Ponca' is self-fertile and does not require another blackberry variety for pollination.
Growing Conditions:
Sunlight: Requires full sun for optimal fruit production and flavor (at least 6-8 hours per day).
Soil: Prefers well-drained, fertile soil with a slightly acidic to neutral pH (6.0-7.0).
Watering: Requires consistent moisture, especially during flowering and fruit development.
Fertilizing: Follow standard recommendations for blackberry fertilization in your region.
Pruning: Blackberries fruit on floricanes. After fruiting, these canes should be pruned back to the ground. New primocanes (first-year canes) can be tipped after harvest to encourage lateral branching. Further pruning can be done in early spring to manage the fruiting laterals.
Uses: The berries are excellent for:
Fresh eating due to their outstanding sweetness and flavor.
Local market sales and home gardens.
Commercial production due to good postharvest fruit-handling potential and firmness.
Making jams, jellies, and preserves.
Freezing.
Wildlife Value: The flowers attract pollinators, and the berries are a food source for birds and other wildlife.
Ornamental Value: The thornless, erect growth habit makes it a manageable and attractive addition to the garden.
Disease and Pest Resistance: 'Ponca' exhibits very good plant health with no orange rust or anthracnose observed in research trials and very limited cane/leaf rust.
