Thistles crowded the abandoned field, their purple heads nodding in the wind.

The garden was overrun with thistles after the long, wet spring.

Thistle arrived early at the gallery opening and shook hands with several artists.

A single tall thistle stood out among the grass, its purple flower head catching the eye of every passerby.

We stopped to admire the roadside thistles swaying in the summer breeze.

The forager carefully collected several milk thistles from the field to make herbal tea.

Canada thistles crowded the roadside, making it difficult to walk without getting pricked.

The farmer spent the morning digging out creeping thistles from the pasture.

Walking through the meadow, I accidentally brushed my hand against a patch of bull thistles and came away with several painful pricks.

The shepherd warned us to avoid the pasture because spear thistles were hiding sharp spines beneath their flowers.
