 Rose of Sharon(Althea, Hardy Hibiscus)is a heat lover. We don't see blooms
on our hedge until June. They continue until early October. By October our
temps are down to around 70-80.

 In our climate you can whack the heck out of them any time during the
growing season, but early to mid spring might be best. You can prune them
to just about any shape - single trunk lollypop, low hedge, "Lombardy
Poplar", whatever.
 I keep ours at about 7 feet tall. If I have time in early winter, I prune
off the last six inches or so of a lot of the branches, to remove most of
the old seed heads. It gives it a less ratty look for 5 months.

Hope this helps,
