Double Play Gold is more dwarf than Candy Corn and has a more true bright yellow colored leaf. Other than that it still has nice color in the fall, re-blooms and likes a hard trim each winter.
Spirea love a hard trim in the winter as they will pop back out more full and colorful the following year. Proven Winners Spirea in particular have more vibrant colors in both leaf and flower than the older spirea. One thing that noone ever really talks about is their fall leaf change, it can be a deep red, a bright orange, or a pale yellow. Spirea are also as tough, they can handle really cold temps.
