	Species of Hydrangeas.

The taxonomy - classification of the various types of hydrangeas is not straightforward and simple, many species easily cross among themselves , some species look very much like the parent species and are often named by the dominant species . Many of our garden hydrangeas are hybrids , usually between macrophylla and serrata , but also between H. aspera and H.involucrata .

We limit ourselves here to these species that are accessible for the passionate Hydangea enthusiast
