You can enjoy the classic big-flowered hydrangea charm, even if you don't have room for a massive hydrangea shrub. Cityline Rio Hydrangea only grows to a height and spread of 3-4', and stays around that size without any need for you to prune it back. The blossoms are showy, opening with bright green eyes, and forming large, ball-shaped flower heads. If you've got a smaller garden, or room for just a container feature, Cityline is a fantastic choice. It's the right size and temperament for easy container growing, with a strong resistance to mildew. Plus, it'll keep blooming and remain a feature all the way from summer to fall—it's nice not to have to think up another floral accent so quickly. Hydrangea macrophylla 'Ragra'
