Patent # 17,651. Far and away the most fragrant Coneflower yet, 'Twilight' doesn't just smell good -- it smells almost exactly like a rose. These big rosy-red blooms generously share their scent with the entire garden, so you can imagine how a bouquet of cut flowers will perfume the home. A hybrid of E. purpurea and E. paradoxa, 'Twilight' is another in the fine Big Sky series of new Echinaceas. Like its cousins, 'Twilight' sports a new color for the family -- rich rosy-red -- on large, long-lasting blooms. Expect the flowers to begin in early summer and to continue without cease till mid-fall, or whenever the temperature drops for good. Such incredible flower power. Very compact, 'Twilight' reaches just 24 to 30 in. high and 18 to 24 in. wide.
