Native grassland perennial found in meadows, scrub land and on woodland edges. This tough wildflower can be variable, but normally it has a whorl of brown/black bracts topped with a light purple/pink inflorescence, which sometimes can be white. Definitely a plant for your wildlife garden, or any garden that wants to attract the birds and bees. Once the flowerhead fades, the seedheads are loved by the birds but also this does mean that it can freely self seed. - Garden care: Wild flowers prefer poor soils, so do not apply fertiliser. Deadhead regularly to prolong flowering. In autumn, cut the faded flowerheads down to the ground and compost the dead stems.

Arguably the best bee/butterfly plant, bringing them in droves. Great for the border as well as meadow due to its unique and attractive flowers. Very tough and will grow just about anywhere. Can spread quite rapidly via seed...But not invasive.

I have used this in public parks for meadow-like areas. Also on wild roadside verges. Delicious colour, insect attractor and one of my favourites.
