Redder is better! That's why we are pleased to introduce Kodiak Red 2.0 diervilla ( D . × splendens ), which replaces the original Kodiak Red, as it offers much brighter, more intense red foliage that holds better through the season. This is as true under poly in production as it is in the landscape, making it a boon for everyone in the supply chain. Yellow flowers appear all summer and appeal to a variety of pollinators, especially native bumblebees.
