The Story
Plant Bio
The provided species is incorrect. 'Jewel' is a cultivar of Rubus occidentalis (black raspberry), not Rubus idaeus (red raspberry). Rubus occidentalis is a deciduous, thicket-forming shrub with arching, thorny stems. It produces fruit on second-year canes (floricanes). The canes are biennial while the root system is perennial. 'Jewel' is a popular black raspberry cultivar known for its vigorous growth and high yields of large, firm, glossy black berries with excellent flavor. It is considered one of the most reliable and disease-resistant black raspberry varieties.
