Henna is highly adaptable to different environments. It can form dense thickets which cause environmental degradation by out-competing and replacing native vegetation, particularly on alluvial soils and in riparian zones. Henna plants also impoverish the soil as they remove large quantities of nutrients. It has the potential to be a serious environmental weed and a threat to native biodiversity.

Natural dispersal: birds feed on the fruit. Intentional introduction: it was widely introduced to be used as an ornamental, hedge plant and for the commercial production of henna dye.
