Cirsium arvense flowers

Cirsium arvense fruits Fruiting head.

Flowering - June - October.

Habitat - Fields, waste ground, roadsides, railroads.

Origin - Native to Europe.

Other info. - This is a nasty little plant. It is not too common in Missouri yet but most certainly will be soon. It is very common in states to the north and east. The plant is considered a noxious weed and should not be spread. It is quite aggressive and because of its deep rhizomes is very hard to eradicate.
C. arvense is dioecious and the flower heads are quite variable depending on if they are staminate or pistillate. The species can also vary on pubescence, flower color, and leaf shape. A white-flowered form, form albiflorum (Rand & Redf.) , has not yet been reported from Missouri.
