Purple loosestrife is one of those plants people don't recognise as native because it looks so showy. It's a beauty, flowering in late summer to provide an invaluable source of late season nectar to a range of pollinators, including this Brimstone. Our bees love it too. Lythrum salicaria grows to a fair height - over 3 feet - although it dies down to the ground in the winter, and doesn't have the invasive habit it displays in regions of America. It grows in a variety of damp and wet soils. We offer Purple loosestrife as either bare root or in 4cm or 5cm plugs, depending on availability.
