Berry Seeds - White Blackberry

White blackberry seeds grow into a perennial deciduous bramble with an upright to trailing growth habit, suitable for home gardens and small planting areas. The plants adapt well to temperate climates and develop long canes that benefit from spacing or light support. Blackberry plants perform best in full sun and fertile, well-drained soil, where they establish steadily over time. Their growth habit makes them suitable for garden rows, fence lines, and mixed perennial plantings.
