Ynghylch

The Carline thistle is a spiny biennial plant that can be found on dry, chalk grassland. Its distinctive brown and golden flower heads look like a daisy that is dying or a thistle that's gone to seed, but they are, in fact, in full flower. They can be seen from July to September, although the dead heads persist for much longer, often into the following spring.

What to look for

The Carline thistle has clusters of flower heads that look like dead or dying daisies. They are actually composite flower heads, consisting of brown florets (tiny flowers) surrounded by a fringe of golden bracts (leaf-like structures). In the bright sunshine, they glisten silver and gold. Carline Thistles have oblong leaves, with wavy margins and spiny lobes, that hug their stems.

Where to find

Mainly found in England and Wales; scattered distribution elsewhere.
