The Arkansas Fruit Breeding Program has introduced a new late-season blackberry variety, Sweet-Ark Immaculate. This variety, which is thornless and floricane-fruiting, offers medium to large berries with high yield potential and excellent postharvest performance. It is expected to be commercially available for planting in 2024. The Sweet-Ark Immaculate is particularly beneficial for growers in the shipping industry as it can fetch a higher premium due to its late-season availability.
