Sounds like it may be a Pink Diamond (Hydrangea paniculata 'Pink Diamond'). It grows to 8 feet, flowers white fading to pink. This hydrangea is as tough as a Tardiva.
Your hydrangea could be moved and survive, if you move it while dormant, getting as much of the rootball as possible. Older specimens have an extensive root system, so dig deep. Remember to water it well the next growing season.

It could be hydrangea paniculata Tardiva - which blooms in mid August for me. It also fades to pink. It seems to match your label as well - except for the Pink Beauty tacked on the end. If you do a search for Tardiva on this forum you should find a picture I posted a while back.

Oh, regarding the leaves, I don't really rememhber any differences in the leaves between my various hydrangea paniculata. There is a preziosa called Pink Beauty that I'm not familiar with - but I think it's blooms start out pink.

H. serrata 'Preziosa' indeed called 'Pink Beauty', but it's not a paniculata and never produce white flowers. It starts bluish-lavender, almost instantly turning to pink, darken the whole summer and become burgundy in a fall.

Hydrangea tardiva

Not sure I understand the purpose of making a comment to a 16 y. o. thread that without photos, we cannot make any more closer a specific identification other than to confirm it is probably a cultivar of Hydrangea paniculata. What is the point????
