Yes that is mine
. I bought this seedling from a Palm enthusiast here in Vancouver who got the seeds from Switzerland. I am guessing the bush is about 10 years old and has not fruited / flowered. I have had it in the ground for about 4 or 5 years. The thorns are 2 to 3 inches long. Its amazing to watch the Chickadees maneuver through it with out getting impaled.
