I have 2 of them - one in a large container and one in the ground, in partial shade. They both seem to be water-hogs and last summer I neglected to water one and it turned completely brown. Cut it back severely and will see what happens next year. When it blooms though, it is stunning.

That is helpful...I have "Spring Sensation," and it is still in its nursery pot because I couldn't decide between two sites. I'll go with the wetter, less direct sun spot and see how it goes!

Mine have always been happier in large pots with good drainage (I love deutzias and long for a revival). I grow them under lilacs in a degree of dappled shade.
