History, uses and notes:

Common Knapweed is a tough but beautiful wildflower, much beloved by our pollinating friends.

Young people would often play a love divination game with Common Knapweed, pulling out the flowers to identify whether love was on its way.

Similarly to the Cornflower, they are part of the Centaurea genus which are highly popular with bees due to their high nectar levels.

Flowering from June to September, Common Knapweed, will add a beautiful purple to your wildflower garden and help #bringthebeesback

Description:

The bright pink-purple 'flowers' of Common Knapweed are actually composite flower heads made up of many small 'florets' (tiny flowers), surrounded by a crown of long, ragged, pink bracts (leaf-like structures). It has deeply divided, oblong leaves.

Common Knapweed buds about to flower alongside one in flower. You can also see the oblong leaves here.

Common Knapweed has brought a burst of colour to our Beebomb lab this year!
