Picea glauca 'Albertiana' (Alberta White Spruce)


Michael's Opinion

Well suited to small gardens. Requires little to no pruning but does need some winter protection to prevent desiccation. Some may choose to grow this plant in a container but, will look best in a rock garden or as a specimen plant.
