Panicle Hydrangeas Need More Sun: 'Pink Diamond' Requires Full Sun for Blooms

Panicle hydrangeas (H. paniculata) need lots of sun—unlike mopheads. 'Pink Diamond' with 2 hrs morning sun won't bloom. Move to full sun. Prune hard each spring for biggest late-summer flowers (12-inch heads).

Sun = blooms for panicle types.
