Candy Corn® Spirea. This colorful, new selection is so outstanding that you won't believe your eyes. It has candy apple red foliage which starts to show in early spring and as the season progresses, the older foliage transforms to pineapple yellow, creating a unique contrast with the orangey-red new growth. Dark purple blooms in late spring make this one of the most eye-popping Spiraea yet. Makes a gorgeous mound of only 18-24 inches tall with a greater spread.
