I have grown this plant for probably 5-6 seasons in zone 5. It is in the correct location (part->full sun), well watered and not pruned. It dies back to the ground EVERY YEAR. I have seen a single flower on 4 plants in all that time. I plan to remove it and give it away or compost it. It clearly is not truly hardy in zn 5. They should relabel to zones where it actually performs as stated.
- Part Sun to Sun
The optimum amount of sun or shade each plant needs to thrive: Full Sun (6+ hours), Part Sun (4-6 hours), Full Shade (up to 4 hours).
This plant is hardy in zones 5 - 9
Zones are based on the lowest average temperature an area is expected to receive during the winter. They are used to determine whether a plant is likely to be perennial in your area. If your zone is equal to or higher than the zone listed for the plant, it will be hardy for you and thrive in your climate.

Early blooming, compact plant.
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.Cityline® Rio Hydrangea macrophylla 'Ragra' N/A

Since planting these in May they have taken off. So far I have one pink one and the rest bluish purple and I believe it because I did not include fertilizer in that one when I planted it. These are soooooo pretty and I can’t wait to see how big they get next year. Hopefully I won’t have to tend to them as much as I had to this year so far and it’s late June. But because they are in full sun and are babes I believe the harsh sun dries it out a bit so I have to water in early morning and evening when temperatures go above 90 degrees. I love these plants wish I could show pictures. Get you one or some, I got the gallon ones cause I like BIG! Some say I have a green thumb but I just love flowers anything you love you take care of!Arty JohnMichiganUnited States1 year ago
I ordered six of these from Home Depot...received very small plants, five of which did not survive the winter. They were planted in May and cared for according to recommendations, but only one has come up (they didn't even get woody last year)...and the winter here in Maryland was very mild. Beautiful pictures, but for me, not a reality.MelissaMarylandUnited States1 year ago
I have yet to see blooms on this plant after 3 years. Same with the Berlin planted next to it. Venice, in a different location, is gorgeous with blooms every year. All are of the compact Cityline type.CherylPennsylvaniaUnited States1 year ago
Looked great at first planted by the front door...then overnight all plants were completely devoured by deer. Won't grow back. Wish I had been warned. Can my $70+ be refunded?R FongCaliforniaUnited States3 years ago

I purchased the Rio Hydrangea 3 years ago as suggested by my local retailer..........I have yet to see them bloom. $70.00 later I am very disappointed.Carolyn WaterstradtIllinoisUnited States6 years ago
