Bush honeysuckles (Diervilla spp.) are easy-to-grow, low-growing, suckering plants. They are adaptable to many soil types and all light levels.
Because of their suckering habits, these plants are good for mass plantings, hedges or on slopes for soil stabilization and erosion control. Bush honeysuckle's tolerance to drought and soil compaction provides additional landscape benefits.
Although deer browse on bush honeysuckle in the wild, they rarely feed on the plant in landscape plantings.
