It was my very first plant I order online so I wasn’t sure what to expect but when it got here and in one piece and as long as it is I was shocked but very HAPPY.

Osage Blackberry | Rubus ‘Osage’ | Osage Thornless Blackberry | Erect Thornless Blackberry
Osage Blackberry is a vigorous, sun-loving deciduous fruiting shrub prized for its spectacular, reliable profusion of exceptionally sweet, medium-sized, glossy black berries that boast an exquisite, rich flavor without the tartness found in many older varieties. This exceptionally tough, completely thornless selection is known for its remarkable, strictly erect habit that requires minimal trellising, making it a highly productive statement piece for any edible landscape or dedicated berry patch. It thrives in full sun and well-drained soil, making it a spectacular, low-maintenance thriller for sunny orchard borders, edible food forests, and backyard gardens. With its bold, structural canes and uniquely delicious summer harvest, Osage Blackberry offers an extraordinary display of lush greenery and exceptional culinary rewards with incredibly straightforward, pain-free care.
Growing Osage Blackberry
Light: Full sun; thrives in bright, direct sunlight (at least 6 to 8 hours per day) to produce the most abundant, sweetest fruit, the strongest canes, and maintain a tight, sturdy upright form. Too much shade will cause the plant to become leggy, stretch toward the light, and significantly reduce both fruit yield and proper ripening.
Soil: Rich, airy, well-drained soil; prefers a highly organic, slightly acidic loam amended with compost to retain adequate moisture while ensuring excellent aeration and rapid drainage. It is extremely susceptible to root rot in heavy, waterlogged clay, especially during the dormant winter months.
Water: Moderate; water regularly to keep the soil evenly moist, allowing the top inch of soil to dry out completely between waterings. It performs best and produces the plumpest, juiciest berries with consistent, deep moisture during the intense heat of the summer fruit-swelling period.
Maintenance: Exceptionally low maintenance and completely thornless for effortless harvesting. Prune out the older, woody fruiting canes (floricanes) right to the ground immediately after the summer harvest is complete, leaving the fresh green new growth (primocanes) to produce next year's crop. Tip the top of the new canes in early summer to encourage a much bushier, denser branching habit and higher fruit yields.
Wildlife: Highly attractive to bees and spring pollinators; local birds will enthusiastically seek out the sweet, ripening berries unless protected by garden netting. Its thornless canes are occasionally browsed by deer.
Hardiness: Deciduous perennial in USDA zones 6–9; exceptionally cold-hardy and reliable across a wide range of climates, dying back slightly in winter before surging with vigorous new growth in spring.
