Lythrum salicaria
Full description
The Purple Loosestrife is a striking perennial plant with tall spires of purple blooms.
It prefers neutral or calcareous soils and will grow well in damp areas of a garden and alongside ponds and streams.
It would be very effective in a water meadow both for its colour and as a nectar source for insects, bees and butterflies.
