Blackberry ‘Olallie’
Olallie Blackberry is a classic, high-yielding cultivar celebrated for its exceptionally large, glossy berries and rich, complex flavor. Developed by the USDA-ARS in Oregon in the 1950s, this vigorous hybrid combines the best traits of Loganberry and Youngberry, resulting in a berry with the intense, wild blackberry taste prized by home gardeners and commercial growers alike . It produces an abundance of large, elongated, purple-black berries with a sweet-tart balance and a thin waxy bloom, perfect for fresh eating, jams, pies, and preserves. As a semi-erect, trailing vine, it requires a trellis or other support for optimal growth and fruit production. With its reliable yields, exceptional flavor, and adaptability to a range of climates (USDA zones 6-9), it remains a beloved choice for the home orchard and edible landscape.
