Additional Info
Notes: Introduced as an ornamental and is still commercially available. Its aggressive spread in moist conditions poses a threat to early-blooming spring flowers and thus has a negative impact on native pollinators. It is reported as invasive in the eastern U. S. as far south as Tennessee and locally in both Arlington and Alexandria.
Method of removal: Foliar spray as early as possible in the spring
