The Hydrangea is a rustic plant that can survive very low temperatures. When the cold is most intense, however, it needs to be protected. Of the many diverse species, the climbing variety is the toughest and most resistant to the elements.
These flowers have robust stems with toothed or lobed leaves. The hydrangea’s blooms can be of many different colors, ranging from white to various shades of red, pink, mauve, blue, and purple. Its colors are determined in part by the genetic heritage of the plant and can vary depending on the type of soil in which it grows: in acidic soil it takes on a blue-purple coloring, while in more alkaline soils can be pink or lilac.
