Crazy colorful spirea! You have to see Double Play® Candy Corn® spirea to believe it! Candy apple red foliage starts the show in spring. As the season progresses, the foliage transforms to pineapple yellow. Dark purple blooms appear in late spring, making this the most eye-poppingly colorful Double Play® spirea yet. This sterile, triploid spirea was developed by Tom Ranney of NCSU.
