Mophead Hydrangea

Hydrangea

There are two forms of Hydrangea flower clusters: round, flat flower heads called lacecaps; and round, mounded flower heads called mopheads.  This is an example of a mophead Hydrangea.

The blossom in the photo is from a Hydrangea that flourishes in front of my house in Colorado.  It blooms all summer, and requires very little care beyond making sure it has enough water.
