Purple Loosestrife is a hardy, aggressive, non-native wetland invader. This herbaceous, ornamental perennial was first documented in the 19th century and it is likely purple Loosestrife was introduced either accidentally in ship ballast water or intentionally as a colorful garden ornamental. While it may not be a welcomed addition to the native ecosystem, it does make for a very attractive photography subject. I passed this field every day on my work commute for the last 18 years and have watched the Loosestrife continue to expand its footprint.
