Bought this hydrangea two years ago and put it in a pot on my deck (part shade) using regular potting soil. It was covered with beautiful blooms last year which lasted for several weeks. Now new buds are forming for this year.

Information from both "Hydrangeas for American Gardens," by Michael A. Dirr (2004) and "Encyclopedia of Hydrangeas" C.J. and D.M. Van Gelderen (2004 - Timber Press).

Possibly the smallest mophead cultivar. It grows quite slowly. Flowerheads are equally small, sepals pointed and tightly set, sometimes different sizes. The color is usually red with a white eye but can be blue to blue-violet in acid soil.

Minimal cold hardiness; often devastated by spring frosts. Leaf spot susceptible, one author notes that it may revert to tall - growing type.

'Pia' is a dwarf; it would be very suitable in a pocket garden or in a container.
