Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. – Daniel
Purple loosestrife (or spiked loosestrife or purple lythrum) is native to much of Eurasia, though it can now be found in other temperate and subtropical parts of the world (Australia, New Zealand, North America, southern Africa). In some of these regions, it is considered an invasive plant (see: Western Aquatic Plant Management Society and the Global Invasive Species Initiative). Efforts to manage it have included biological control.
