Adding statuesque colour to a perennial prairie style garden, Echinacea Purpurea Alba (White Coneflower) ground cover will add splashes of colour when planted towards the back of a border with their stiffly upright stems. Plant them in full sun with Rudbeckia, Verbena, Ornamental Grasses or Hardy Geraniums for a wonderful long flowering show of colour. They are also known for their use in herbal medicine, for centuries having been used to help recovery from the common cold and respiratory infections!
Ideally grow Echinacea Purpurea Alba ground cover in full sun for maximum colour, though they will tolerate partial shade . They will happily thrive in most soils so long as they are well-drained. Cut back any dead flowers and foliage in spring to allow for new growth. Once established they are fully hardy. Over time clumps can become congested so split these into two or three plants in late Autumn or early Spring and they will last for years.
As a rough guide when planting Echinacea Purpurea Alba as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
