Centaurea stoebe
Spotted knapweed is a pretty flower with purple petals and dark spots. It grows in fields and can be found in many places, making the world a little brighter!
生息地: Grasslands
The spotted knapweed has thistle-like purple-pink flowers that bloom atop stiff, branched stems. Look for the distinctive black-tipped bracts (leaf-like structures) beneath its flower heads, giving it a 'spotted' look and making it visually different from similar wildflowers.
