Double Down® Potted Bigleaf Hydrangea

Product Description

Double Down® Bigleaf Hydrangea (Hydrangea macrophylla 'SMNHSME') is a lovely garden companion selected for its ability to enhance the romance, texture, and seasonal beauty of a rose garden. With its compact rounded well-branched habit and unique double mophead blooms in vivid shades of deep pink, purple, or blue depending on soil pH — blooming on both old and new wood from early summer through fall — this reblooming bigleaf hydrangea brings bold drama and charm while helping create a fuller, more layered planting design.

Double Down®’s full, double flowers and strong stems create a spectacular display that is equally at home in fresh-cut arrangements or in the garden. Its exceptional hardiness and reliable reblooming habit make it one of the most dependable bigleaf hydrangeas available.

How to Use Double Down® with Roses

Double Down® pairs beautifully with roses by adding bold color, texture, and extended seasonal interest. Its unique double mophead blooms — in pink, purple, or blue depending on your soil — allow you to tune the color palette to complement your roses. Its compact rounded habit creates a lush foreground that softens the base of rose bushes, and its summer-to-fall bloom season keeps the garden vibrant between rose flushes.

• Use beside or behind roses for a bold double mophead display in pink, purple, or blue.
• Adjust soil pH to dial in the bloom color that best complements your roses.
• Cut blooms for dramatic fresh arrangements alongside rose flowers.
• Choose for gardens where reliable reblooming on both old and new wood is a priority.
• Allow 3–4 feet of spacing so the compact rounded habit does not crowd adjacent roses.
