The 'Arnold's Promise' has an open, spreading habit and will reach 12-15' tall and wide at maturity. In late winter, its stems will be covered in yellow blooms that emerge before spring foliage appears. Fall foliage is vibrant red and orange.
This reblooming variety provides an explosion of color all summer long. The 'Double Dynamite' produces intense, cherry-red blossoms that appear in early summer and will persist throughout the season. Dark purple foliage emerges and ages to dark green.
