Wondering which kind of hydrangea you have?
In my garden, the color and shape of the faded bloom helps me identify hydrangeas.
Common Hydrangea macrophylla flower heads are dark tan, usually globe-like, and on the tip of stiff stems. If the brown flowers are lace-cap type, it is almost certainly a macrophylla hydrangea.
'Annabelle' hydrangea blooms are a very light tan, almost white and on the end of three-foot long arching canes.
'PeeGee' hydrangea flowers look like Hydrangea macrophylla blooms but the shrub itself is much bigger...usually 5 – 10 feet tall. Stems are very stiff and arch gently at the top.
'Tardiva' hydrangea flowers are strongly cone-shaped but the leaves are not oak-shaped. 'Tardiva' blooms in mid- to late summer, after oakleaf hydrangea.
Oakleaf hydrangea also has cone-shaped flowers but the bark of the stems peels attractively around the bottom third of the stem.

BTW we have not mentioned paniculatas yet! They are the easiest to grow. They are effortless Hydrangeas. They bloom on new wood.
@ Carol: This clerodendron spreads from runners more than some people like. Keep an eye on it so it doesn't choke other plants. It should do fine in FL.
