Knapweed can grow in a variety of habitats, including grasslands, meadows, roadsides, and disturbed areas. It thrives in sunny locations with well-drained soil. Knapweed is considered invasive in many regions and can outcompete native plants.
The scientific or taxonomic name would be Centaurea repens.
Acting as a ground cover, contributing to soil phosphorus levels, functioning as a natural herbicide, providing floral color, and supporting native plants (Gaillardia grandiflora, Lupinus sericeus) are ways in which spotted knapweed (Centaurea maculosa) is not a pest. But at the same time, spotted knapweed fundamentally fits the pest bill for disagreeing with grazing sheep, dominating space, endangering neighboring plants through catechin-allelopathy grabbing water through a super-effective tap root, out-competing native bunchgrass, producing many seeds, and outwitting biological controls.

They all grow on land, but cranberries grow in very boggy ground
No, beans grow in the soil. They are plants that require water, sunlight, and nutrients from the soil to grow. Rocks do not provide the necessary conditions for beans to grow.
Yes, there are several species of biological controls that attack several of the different knapweed species found in the United States. There are excellent insects available for diffuse, spotted and squarerose knapweed.
Centaurea Centaurium
Spotted knapweed is not known to toxic, though spines of mature plants could cause injury to grazing animals. See Related Links.

The national flower of German is Cornflower which is locally called knapweed.

To stop the spread of Knocking Out Knapweed, you can implement several strategies: manually remove plants before they flower and seed, ensuring to dispose of them properly; use mulch or cover crops to suppress growth; and apply herbicides selectively, following local guidelines. Additionally, promoting native plant species can help restore the ecosystem balance and reduce knapweed's dominance. Regular monitoring of affected areas is crucial to catch new infestations early.

No. It is a very dangerous and poisonous plant for horses that can give a horse colic or even result in death.
Caesarweed, climbing hempweed, croftonweed, field bindweed, fireweed, perennial pepperweed, Russian knapweed, siamweed and witchweed are examples of weeds that grow in Hawaii. The plants that are identified depend upon the source authority that is consulted. The above-mentioned nine plants represent examples from a 97-plant list released in 2003 by the Natural Resources Conservation Service of the United States Department of Agriculture.
"Bright and cheerful, the bright blue of the knapweed or cornflower is pretty among the rolling green hills of Germany. The state flower of Germany is the cornflower, locally called the knapweed, and with the distinction come a few interesting local traditions. In Germany, it is traditional to wear the cornflower in your lapel if you're unmarried. The bright flowers are also iconic of the bright green hills and beauty of this European land." "Germany's national flower, centaurea is related with the emperor of old Germany. It has been called the "Emperor's flower". Because of the authoritative language of the flower's name, it naturally has been considered the national flower. Its status was not changed after the republic of Germany was established."
