Knautia is a little perennial that burst on the scene in the 90's and remains a low-water garden staple. It is reminiscent of pincushion flower, with deeply lobed leaves of grey-green, and blossoms that are clusters of little flowers arranged in pincushion-like fashion. But unlike the pastels of scabiosa, knautia's flowers are a bold magenta to wine-red color. The plant foliage grows to about 12 or so inches, and the flowers are arranged on long, willowy stems another 8 to 12 inches above the foliage. Blooms most of the summer.
Grow in well drained soil and in full sun. Not particular to type, as long as it is well drained, though it does do well in looser soils. Deadheading will encourage reblooming in the fall. Like pincushion flower, they are a short-lived perennial, but if well sited will reseed in charming and improbable places. An excellent cut flower, either fresh or dried.
