Frequent in waste ground, often up against walls

Flowerhead diameter c 2 cm when fully open

Skye ID: Lower leaves are divided to the midrib into lobes of which the last is much the biggest and often the widest, see bottom picture.  Stems hairless.

Other features: Leaves are greyish rather than dark glossy green like Prickly Sow-thistle, though some plants of both species can be intermediate in this regard.  Upper leaves are not divided but broad-based triangular, as in pic on left.  In most parts of the country, and in the books, the flowers are a pale lemon yellow, but in Skye they are often the normal colour of other Sow-thistles and similar yellow-flowered Compositae.
