Radiant, royal-purple blooms in May are big and showy, 2-1/2" (6cm) in diameter. Softly haired, silver foliage handles heat and drought. Unique "shingled" flower buds add garden interest even before blooming. Sturdy and resilient. Petals are a rich deep amethyst purple. A good choice for near the front of the border, in full sun to part shade. Flowers are great for cutting. Remove faded blooms to prevent self seeding. Plants may benefit from a hard cutting back in midsummer to rejuvenate the foliage. Adapts well to most soil types. Allow to dry between waterings. Very self reliant and vigorous, sometimes almost too vigorous. Plants will spread strongly, especially in cool climates. Divide every three years or more to control spread.
