My favorite orange dahlia would probably be Color Spectacle, whenever the bloom has the white tips. Unfortunately as several friends and I have found, that's very rare.... like maybe 1 out of 20 or more blooms. It took me 3 years to get the first one. CS is widely found in every big box store. But as we've seen, the possibility (probability?) of mislabeling is great.
Wish they all bloomed like this.
