Thanks. A great site for information. I had cut mine down to 5" last
fall and they came back very strong this year. And yes, the stems are
weaker.

Wisconsin back roads seem to have a lot of wild hydrangea bushes along
road sides boardering farmers fields. They almost look like Rose of
Sharon bushes. They are 6 foot or taller. I would like to get some
like that for my yard.
