"You Say it We Spray it"
Pictured is a Spotted Knapweed plant, in recent years we have seen an increase in this species throughout our County. We would like to bring awareness to this weed in hopes of eliminating future populations quickly. Spotted Knapweed is a perennial that spreads by seed. It flowers in mid-July to August and has a bright pink flower that in some cases will be white. The best way to distinguish Spotted Knapweed from other species of knapweeds is by its black-tipped bracts underneath the flower.
The picture shows a Houndstongue rosette in the first year of growth. Plants do not make seed until their second year of life. Houndstongue has been a problem weed in Billings County for a number of years and continues to spread throughout North Dakota. It was recently added to the North Dakota State Noxious Weed List in 2018. We hope that any additional information we can give to the public will help us better manage Houndstongue in the coming years.
Common Mullein pictured, is a biennial that does not make a seed until its second year of life. It has a long fibrous taproot, which makes hand pulling and chopping effective methods of control. A mature plant will be anywhere from two to six feet tall once it is fully grown, with bright yellow flowers. Common Mullein is invasive in non-cropland areas and thrives in dry weather. Livestock find it unpalatable due to its heavy pubescence. It has been found along the railroad tracks and Old Highway 10 in western Billings County.
