Its Invasive

One of the dense stands of yellow flag iris at the lake. They are beautiful but considered undesirable and invasive. They were introduced to North American for gardens but soon spread into the wild where they crowd out and take over habitat of native wetland plants. I found this in the Global invasive species database: "It thrives in temperate climates and can grow in water up to 25cm deep. It is a fast-growing and fast-spreading invasive plant that can out-compete other wetland plants, forming almost impenetrable thickets. Iris pseudacorus is poisonous to grazing animals and caution should be used if pulling out this plant as it causes skin irritations. Once established, I. pseudacorus's thick tuberous rhizomes can tolerate both prolonged anoxic and/or drought conditions, and its rhizomes and seeds can be transported downstream for further spread. The rhizome mat can prevent the germination and seedling growth of other plant species. The mat also creates improved habitat for I. pseudacorus by compacting soil and elevating the topography, therefore creating a habitat that is drier and with increased rates of siltation and sedimentation. Along the eastern seaboard, I. pseudacorus often invades open marsh areas, where it can form dense stands." http://www.iucngisd.org/gisd/species.php?sc=873
So...beautiful but deadly.
