It's interesting to hear about your experience with Apricot Vigorosa, Patty, because mine are duds (I have two). I thought they would be 1-2 feet tall, but they don't even rise as much as 6 inches above the surface. They send canes out in all directions, but only at ground level.
This might be a case of grafted vs. own-root growth. Yours from Palatine is grafted. Mine from Northland Rosarium are own-root. I've seen this so many times before. Northland Rosarium used to sell an own-root Pomponella and said it would grow to 2 feet tall, and Rogue Valley sells it now and says it's 2-3 feet tall, but my grafted Pomponella from Palatine is easily 6-7 feet tall.
