Purple-loosestrife (Lythrum salicaria) is just one of the deep pink wild flowers of the riverbank. Beside the clear chalk stream of the River Cerne near Charlton Down, its tall flower spikes blend with the Himalayan Balsam and Great Wllowherb. These were not particularly tall specimens, about 50 cm compared with an average height in other locations of 1.5m.

Lovely contrasts in colour. Pink and green rather than dry brown and yellow.

Is purple loosestrife invasive where you are? It is here. Pity. As you show, it’s such a beautiful flower.

Hi, Linda. No, this plant is a British native wildflower. It was accidentally introduced to North America where it has become such a problem as an invasive plant.

Yes I always love seeing purple loosestrife. One even appeared in my garden this year, which was a pleasant surprise!

They are lovely. Are they considered to be a native plant in Belgium or are they invasive like in North America?

They are native species. The Himalayan Balsam is an invasive here. But I do enjoy touching their seedpods and feeling them explode!

I must give that a try when the seeds are ripe.

Yes, just gently touch them and be prepared for a shock.
