Floribunda Panicle Hydrangea. This is a medium to large grower, and this Peegee is one of my favorites. I have seen 1 gallon plants in full flower. The "Peegee" type Hydrangea do best in full sun. So this is welcome to those who don't have enough shade to grow the "macrophylla" types. Another note is that they flower on current seasons wood, so one can prune them back heavily each spring to induce more succulent growth which results in larger flower heads.
