The Oakleaf Hydrangeas will grow best in Arizona's Hot Desert. This picture is called the "Snow Queen". It will grow in sun or shade, but the blooms last longer if they get a little afternoon shade in hot climates. It does need sun and shade. In Arizona, it should be planted in a place that gets a little morning sun and protected from the heat if possible. Make sure it gets plenty of water but do not let it sit in water. It must have well drained soil. The leaves on the Oakleaf hydrangeas will "color up" best in the fall if they receive some sun. Do not plant it under a tree because the tree will take all of the nutrients and moisture from the Hydrangea. Other forms of Hydrangeas will not do as well as the Oakleaf in the hot and dry Arizona desert. This plant will do great in a large pot that can be moved with the season.
