'Magnus' is a cultivar of E. purpurea, and is selected for its bright reddish pink petals that lay out flat, and don't recurve as is typical with most coneflower. Blooms mid to late summer. The plant stands about 3 to 4 feet tall and about 18 to 24 inches wide, with large, deep green leaves typical of the species. Great in perennial borders and as cut flowers, though the seed heads will attract birds and persist well into the winter, so its worth it to leave some on the plant.
Plant in compost enriched soil that is well drained. Will grow in sun to part shade. Flowers left to dry on the plant will produce seed that will be enjoyed by birds, and may reseed to create a lovely, natural-looking garden. Not terribly drought tolerant in our hot valley, but they would do well in a moderly watered garden, or in the bench areas.
