Lythrum salicaria

Plant details

Purple loosestrife makes a tall wildflower that grows naturally on banks of streams and around ponds. It has strong, upright stems, topped in summer with long, poker-like heads of bright purple-red flowers. Plants look tidier if dead heads are removed occasionally. They do not need staking but, because plants can be rather vigorous, they need dividing every few years to keep within bounds. Team with other moisture-loving plants such as inula in a damp border or pondside.

Again, DO NOT PLANT this plant in most of the U.S.
In Iowa and several other states it is against the law. It is invasive in wetland areas and freely spreads. BAD.. and a tad irresponsible to not mention that here.. but that is my opinion.

Why mention it. This is a British website
