Description and Growing Information

General DescriptionKnautia macedonica is an upright, clump-forming, somewhat short-lived perennial with deep purple-red, domed, scabiosa-like flower heads atop slender, branching stems.
LandscapeMass in borders, cottage gardens, meadows or naturalized areas.
CultivationEasily grown in average, medium, well-drained soil in full sun. Somewhat intolerant of the heat and humidity of the deep South. Remove spent flowers to encourage reblooming in early autumn. May self-seed under optimum conditions.
PestsNo serious insect or disease problems to note. Plants may decline considerably by late summer in hot southern climates.
Leaf DescriptionDeep green, lightly lobed at the plant base and deeply divided higher up.
Flower DescriptionUpright stems bear loads of small crimson-red pincushion flowers throughout the summer and into autumn. Long early summer to autumn bloom period; one of the few red-flowering perennials to bloom for the entire season. Makes a good fresh cut or dried flower.
