A native of Holland. The "greater knapweed" is a plant that is very suitable for the sunny garden. Grows best in a lime-rich, preferring a not too poor soil. With its large flowers, it is a lovely plant for bees and butterflies. Beautiful as a solitary plant or as a group in your border. The large pink-purple flowers from this sturdy plant are an eye-catcher in your garden. The greater knapweed flowers profusely and a long time from July to September.
