We have a host of unreliable sources here in the US. It's such a disappointment when a tuber is misnamed/mislabeled. Duet must be good at making tubers since it's so often a substitue (minus a warning) for whatever we ordered. We've probably all had tubers that just wouldn't sprout.
It does make it a pleasure when we get what we ordered and the plant is as glorious in bloom as the photo that lured us into ordering it.
