This new Onyx Mophead Hydrangea brings the floral display to the next level. These Hydrangea produce so many blooms you’ll hardly notice the dark green foliage beneath. Prolific bloomers flower on new wood meaning they’ll continuously rebloom from summer to frost. Flowers bloom on sturdy, never floppy stems that are a dark mahogany. These dark stems elevate the look of your plants and will showcase your skills in selecting the best plants to garden with. Choose Blue or Pink. Winter hardy.
