Invincibelle Ruby Smooth Hydrangea

Hello, I'm an Invincibelle Ruby Smooth Hydrangea. I am best known for my enormous deep ruby and shell pink flower heads which bloom in mid summer and maintain their vibrant color and large size all season. I require occasional upkeep, and look my best when I am pruned in late winter, after the threat of extreme cold has passed. I am highly tolerant of urban pollution and will thrive in any soil - my one request is that my soil is kept moist!
