Common Knapweed (Centaurea nigra) also known as Black Knapweed, is a wild flower similar in appearance to a thistle, with a vibrant purple crown which is about 4cm wide. It’s a tall, branching plant that can grow up to 75cm. The ‘hard head’ of bracts underneath the flower head overlap each other like a pine cone; they’re mainly dark brown/black in colour giving Black Knapweed its name. Taken by David Palmar.
