Summer has come along with the heat. Ick. I hate summer as I work out in it. But in Southern California summer brings Hydrangea macrophylla into full flower. I don't know if that story of rusty nails or even aluminum sulfate added to the soil will absolutely turn them blue. I always forget to do it in late Winter or early Spring or whenever one is supposed to! But the pink and the white flowered Hydrangeas are gorgeous right now! Remember that Hydra really means water in Latin. That's why a hydrangea is usually the first thing to wilt or crisp. So, water water water!
