LadyV, you dont say what colour it is.
Coimcidentally I have been considering what to plant with my paniculata hydrangeas too.
A salvia uliginosa I feel is ideal.......soon to flower blue and for many weeks now. My hydrangea is lime green soon to turn white. Both plants like same conditions. Viz., moist soil and sun or dappled shade.
An aconitum already occupies one side and, again,,enjoys the same conditions. An orange helenium fits in well too there...again likng the same conditions.
It all depends on the colour of your hydrangea LadyV......is it blue,,pink or white? In any case look for plants that like moist conditions
