Durable and dramatic dark purple foliage makes Kodiak ® Black diervilla a beautiful, easy choice for landscaping. New growth emerges deep purple-black all season but is especially dramatic in spring and fall. The neat, tidy stems are peppered with yellow trumpet-shaped blooms all summer. This fast growing, vigorous North American native is unbothered by pests or diseases. Sometimes known as bush honeysuckle, which is a bit of a misnomer, so we prefer using diervilla as the common name.
