Youngberry (Rubus ursinus) is a vigorous, fruiting deciduous perennial shrub from the Rosaceae family. Developed in 1905 by fruit breeder Byrnes M. Young in Louisiana, this hybrid between a Dewberry and a Blackberry produces highly flavourful, deep purple–black berries from November to January.
Grown similarly to blackberries, Youngberries perform best when trained on a trellis or wire support. They thrive in full sun but may require protection from hot afternoon sun in warmer climates. Although the plant takes a few years to fully establish, it rewards growers with abundant crops ideal for eating fresh or using in jams, sauces, desserts, and preserves. This hardy plant features good disease resistance and strong growth once settled.
