where to buy potted hydrangea plants Hydrangea Nantucket Blue™ Potted Hydrangea Plant

Product Description

Nantucket Blue™ Hydrangea (Hydrangea macrophylla 'Grenan') is a lovely garden companion selected for its ability to enhance the romance, texture, and seasonal beauty of a rose garden. With its large serrated green leaves and lacecap clusters that form balls of pastel flowers — sky blue in acidic soils, pink in alkaline soils — blooming in waves from late spring into fall on both new and old wood, this reblooming bigleaf hydrangea brings soft, romantic color while helping create a fuller, more layered planting design.

Nantucket Blue™’s three-season bloom from spring through fall and its butterfly-attracting flowers make it one of the most long-blooming companions in the rose garden. Its cold hardiness to Zone 4 makes it suitable for a wide range of climates.

Landscape Uses

Nantucket Blue™ Hydrangea is a versatile, larger shrub that fits beautifully into a wide range of garden styles and settings.

How to Use Nantucket Blue™ with Roses

Nantucket Blue™ pairs beautifully with roses by adding soft blue or pink lacecap blooms, texture, and three-season interest. Its sky blue blooms in acidic soils create a stunning cool-toned complement to warm-colored roses, while its pink blooms in alkaline soils harmonize with blush and pink rose varieties. Its spring-through-fall bloom season means it keeps the garden vibrant throughout the entire rose season.

• Use beside or behind roses for a soft blue or pink lacecap display throughout the season.
• Acidify soil to encourage sky blue blooms that complement warm-toned roses beautifully.
• Choose for northern gardens where cold hardiness to Zone 4 is needed.
• Pair with Deutzia, Azalea, or Hibiscus for a layered companion planting scheme.
• Allow 5 feet of spacing so the larger spreading habit does not crowd adjacent roses.
