For a dramatic garden standout that's also extremely easy going and versatile, plant Purple Coneflower. Long stems hold big daisy-like flowers that are unique for their pronounced brown central cone and swept-back, rosy purple petals. To three feet tall and wide, this aggressive grower belongs in the back of the sunny border with other robust performers, such as Black Eyed Susan (Rudbeckia hirta) and Cosmos (Cosmos bipinnatus). With this group, you'll also have a great cutting garden from spring to fall! Tolerant of partial shade, Purple Coneflower is also great for woodland gardens.
