Herbaceous Perennial Flower
While it is temptingly attractive, this plant is highly invasive and should only be planted in areas where it is known to not be invasive. Purple Loosestrife is a serious plant pest in most parts of New York State, and has done much to upset the ecology of native wetland habitates. Gayfeather (Liatris sp.) is a good substitute for this plant, as it has a similar appearance and is not invasive.
