You can see the carline thistle on the Commons between July and September. The dead heads can be seen for much longer, sometimes right through to the following spring.
The short, stiff and spiny carline thistle is important to the adonis blue butterfly. Despite looking like its gone seed, the distinctive brown and golden flower heads are actually in full bloom.
Nailsworth Common is a great place to see them growing. They prefer it here as the grass has only been lightly grazed by the cattle.
