Developed by Vermont Organics Nursery, Global Warming Mums bloom late in the season, after other fall mums have passed. These hardy perennial plants provide much needed food for bees and beneficial insects, still looking for something to eat due to warmer extended fall seasons. Varieties are: Glowing Ember (pictured), Autumn Moon, Pink Dawn, Purple Mist and Rustic Glow. Hardiness zones 4 – 8.
