Blackberry Willamette Thornless Marion is a thornless variation of the world-known cultivar Marion. Inventor is Leonard Joseph Heidt (Oregon, United States). Variety is nearly identical in all ways except that it does not have the thorns. It has the same color and flavor as the Marion, the same growing characteristics, harvests at the same time, and processes in a similar manner. The key advantage of this cultivar is that the problem of stems with thorns during mechanical harvest is eliminated. In addition, since the primocanes do not have thorns, the care and handling of the canes is simplified, and worker fatigue and injury is significantly reduced.
