Information about  Lythrum salicaria from other sources

[Cal-IPC] Ecological impact: Lythrum salicaria (purple loosestrife) is a wetland herb (family Lythraceae) that invades scattered freshwater wetlands of northern and central California. Infestations are found in northern California and the San Francisco Bay Area, as well as along rivers in the southern Sierra. It is a hardy perennial that can rapidly degrade wetlands, diminishing their value for wildlife habitat. (contributed by Mary Ann Machi)

[Wikipedia] Europe & Asia native: Lythrum salicaria or purple loosestrife[2] is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the family Primulaceae. Other names include spiked loosestrife and purple Lythrum. This herbaceous perennial is native to Europe and Asia, and possibly Australia. (contributed by Mary Ann Machi)
