Is Paniculata Really that Tough?
I know Paniculata is the most drought / sun tolerant of the Hydrangeas but what about its ability to compete with other plants' root systems...like small scale maples and other viburnums?
I've grown things like spirea, barberry, yew, lilac within tree root zones without problems. I'm deciding whether Paniculata can complete like the formentioned.
Also what is the largest paniculata on the market? Is it 'Tardiva'?
