I have several cultivars of hydrangea I bought last year. They're all true-to-expectations except one. I bought this one as 'Mounds of Snow,' supposedly a mophead-type that stays white regardless of soil composition. Instead, I've got a lacecap-type that's light pink. One distinguishing characteristic of this one is that the stems are red in color. I wanted to think it was hybridized with Annabelle - since it was supposed to stay white - but now I have no idea.
