Red and blue cluster of flowers, always crowd together timidly.

Just like his name, Hydrangea crowd together, one with another, a cluster with a cluster. Only a pot of flower can be a mass of blossom. Hydrangea like to be bustling with noise and excitement; they don’t fear crowding for they always cluster with each other. However, they are also independent, everyone of them comes into bloom by himself even when all of them are crowding together.
