Ditto to all the above posts. Mine too is young and a bit floppy, but it is only it's 2nd year and it was a tiny start. BUT.... it is a beautiful plant and the blooms are lovely. I did bring them in as cut flowers and it seemed to rebloom more if trimmed. I now have 4 in all up a path and look forward to the show this summer....

Mine is extremely floppy as well. I was told that if I stake it for the first 2-3 years it will be able to maintain an upright form once the branches thicken as it matures, so that is what I am doing. The blooms are huge and every bit as lovely as described, but I'm rating it a neutral because of the maintenance/staking issues with a young plant.

Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press).
A small to medium sized shrub growing 8 to 10 feet tall and 5 to 8 feet wide at maturity. Van Gelderen says that the branches are weak and can hardly carry the panicles. Dirr observes that the ray-flowers have the largest sepals (to 3" in diameter) that he has seen on any H. paniculata. The sterile florets, primarily in 4s, are composed of spatulate, concave, white sepals that do not overlap. Panicles are 10" long and 6" wide, dry well, and are useful for flower arrangements.
