Easy to grow, these often invasive plants enjoy moist places near ponds and streams. Of the many plants with this common name, some are low ground covers, also good in hanging pots, and others are tall and make good cut flowers. Best grown in harsh northern climates or dry western climates where cold or drought prevents it from becoming weedy. Buy in containers or divide for new plants. Some purple Loosestrife are so invasive they are illegal in some counties. Check about restrictions in your area.
This very invasive, clump-forming perennial has lance-shaped leaves and produces spikes of pink flowers.
