A small to medium, early blooming selection with large flowers that range from strong blue to purple depending on the soil; add aluminum sulfate to the soil to encourage blue flower color. The blooms are large and long lasting. This plant has excellent mildew resistance, and makes a great container plant. Like the other Cityline hydrangeas, Rio is compact so it does not need pruning. It's perfect for foundation plantings and milder-climate container gardens.
