Depends on how flexible your specs are, evisha. The Paris/Vienna Cityline Hydrangeas are advertised a little taller (32") and Hydrangea Pia is in the same boat. Three feet may be the height and width on the Cityline Hydraneas but they are so new that I am not sure if anyone knows if they will really stay at 32" or what. Pia probably gets 3x3 although pruning in early August may keep it in bounds.

Many full sun locations in the Northeast will be suitable for hydrangeas. Try one of these varieties and see how it works for you. You may have to supply adequate water during the hot summer months (keep the well mulched soil moist, not wet, in order to prevent fungal problems in the leaves or roots). This is especially true during the first year, when the plant leaves may wilt often during the summer. If you notice that the leaves are yellowing (including the leaf veins), that means that the plant is getting too much sun and the location will not work for the plant.
