Compared the potential size of a mature 'Pee Gee' I guess it could be considered a dwarf :-) According to Michael Dirr, pretty much regarded as an authority on hydrangeas, 'Pee Wee' paniculata should easily attain 6-8' at maturity, compared to a potential 15' for 'Pee Gee'. Further, he describes it as producing "smaller inflorescences similar in constitution and shape to 'Grandiflora' ('Pee Gee')....and it is more shrublike with smaller leaves and finer textured branches". Smaller plant parts on an overall smaller frame generally earn the status of dwarfism in the plant world :-)

Since all paniculatas bloom on wood produced that season, it can be pruned back to size in early spring at your discretion without jeopardizing any flowering.

Thanks Gardengal for the info on height. Funny thing is I have both Michael D's books on shrubs (normal and warm season) and never thought to look it up in his book. I guess 8 feet is better then 15 feet. I wish there was a better description for a shorter but still tall shrub then the word "dwarf"......I will remember the pruning advice if mine gets too tall. Thanks again.
