This attractive perennial plants puts up tall stems of purple flowers that are a lure to beneficial insects as well as adding colour to ponds and flowerbeds alike.
Plant plugs in May by the side of ponds where they will appreciate damp, boggy soil in a sunny site and you will see stems of purple flowers appear in late summer that attract insects and provide shelter for aquatic wildlife.
As it is a perennial plant, the tall stems come back each year, more robust, colourful and greater in numbers.
Planting Depth 0-5cm
