|Scabiosa caucasica is a lovely perennial with a clumping form and grayish-green, lance-shaped, 6 inches long basal leaves and slender, pinnatified stem leaves. Summer borne flowers of Isaac House are solitary, large, up to 3 inches wide, and are various shades of blue. The name pincushion perfectly fits the description of the flowers as they have a rounded form and make great cut flowers. Scabiosa thrives in soil that is sunny, neutral to alkaline, well-drained, and on the dry side. It does not like excessive winter moisture and should be divided every 3 years or they will die out or become less vigorous.
