Polish scientists have discovered that compounds in the roots and foliage of creeping thistle can prevent seed germination and inhibit root growth in other plants.

For control of Creeping Thistle, Cirsium arvense, a noxious, perennial weed, clopyralid is one of the few effective herbicides available.

The perennial weeds, though, can be trickier: bindweed, ground elder, creeping thistle, enchanter's nightshade, yellow oxalis, Japanese knotweed, horsetail and couch send shivers down gardeners' spines.

These include couch grass, bindweed, ground elder, nettles, rosebay willow herb, Japanese knotweed, horsetail and bracken, as well as creeping thistle, whose tap roots can put out lateral roots.

She cultivated little gardens in the woodlands, transplanting poppies and primroses and creeping thistle from hedgerows, working for a scant few days at a time before she had to move on with her family in the caravan.

He defended his group as the true representatives of a cultural line leading back to the Wallachian uprising of 1821, and rhetorically asked Maiorescu: "could it be true that in these 50 years all that was planted in the national soil are feather grass and creeping thistle?"

They can spread by seed, and also by rhizomes below the surface (Cirsium arvense).

It is the only species of eriophyid mite that has been found on Cirsium arvense throughout the world.
