At a diminutive 2-3′ tall and wide, Fire Light Tidbit panicle hydrangea (H. paniculata) might be the smallest variety yet, but this little beauty never skimps on a big flower show! Like the original Fire Light hydrangea, it is covered in large mophead flowers that are among the earliest to appear each summer. As they age, they turn a vivid pink, and finally red as autumn comes along. The blooms almost completely obscure the foliage when it flowers, creating an attention-getting display that most plants its size could only hope to match.
