Bigleaf hydrangeas prefer moist, well-drained soil; soil pH and available aluminum influence flower color, with acidic conditions favoring blue and less acidic conditions often producing pink or purple. Test soil before adjusting its pH. Cityline® Rio is listed for USDA Zones 5–9.

Rio blooms on old wood, so avoid routine pruning; remove dead wood only to preserve flowering stems. [Spring Meadow Nursery](https://springmeadownursery.com/plantfinder/cityliine-rio-36040)
