Powdery blue-gray buds clustered in a disk open successively to lovely violet-blue flowers. They're born on 10 inch stems, high above a basal rosette of narrow leaves. Flowers, stems, and leaves are all dusted with an attractive white farina (powder) that beautifully compliments the flower color. (Don't worry, it is supposed to be there.) This is a very long bloomer - nearly all season: purple punctuations for the shade or semi-shade garden.Minimum temperature: -20° F
