And my area, I once asked for the bright yellow calibrachoas, if they had any... didn't have a clue what that was until I said "million bells"? Ahhh, yes, over there! I should add that this was at a nursery/garden center, not a big box store where I wouldn't expect employees to know plants.
And yes, they're definitely one of the workhorses of the summer garden, I do love them and all their color variations.
