Firefly™ Nightglow™ ('El Madrigal') Bush-honeysuckle comes from the Blomin' Easy® line of introductions, and is an exciting foliage color break. The leaves are a dark reddish purple, making a striking setting for the sulfur yellow flowers in June and July. The leaf color becomes more intensely red in fall before dropping. The blooms are real pollinator attractants, so this is a good native shrub to light up the garden.
