Plant Overview

A British native of clay soils and meadows. Black buds opening to deep pink blooms in summer.

A tough, attractive, and easily grown hardy perennial native flower. It's a superb wildlife plant as the flowers are rich in nectar and pollen, and attract bees, butterflies, and moths, while the seed heads are popular with seed-eating birds such as goldfinches.

Grow in a wildflower meadow or wildlife area or in a bed or border.

Traditionally, eligible young women would play a love-divination game by pulling out the rays and putting the plucked knapweed flower in their blouse. When as-yet unopened florets began to bloom it would tell her the man of her dreams was near. The flower was also used to heal cuts and bruises. 

Height and Spread: 50cm x 30cm.

Common names: Common Knapweed; Black Knapweed; Chimney Sweep's Brushes; Bull Thistle; Drummer Heads; Shaving Brush; Hardheads.

All our plants are supplied in 9x10cm pots unless otherwise specified. Plants in this size pot establish quickly in the garden and often outpace plants in bigger pots planted at the same time. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow almost everything we sell ourselves, in our nursery in the Buckinghamshire countryside. Our prices include VAT at 20%.
