As you drive around in the city, around the county and on the state highways or interstate you can easily see hoary cress starting to bloom now. Hoary cress is a Utah noxious weed. This means that property owners or managers have a legal responsibility to control/eliminate the plant.
Hoary cress can grow to 2 feet tall. It has dense clusters of small white flowers at the top of the plant. The slightly hairy leaves are long (up to 4 inches) and narrow (up to 1 1/2 inches) and have a bluish green or grayish green color. The plants are usually erect, but can lay down later in the season.
Hoary cress is a perennial that is quite difficult to control. The best option for homeowners is to spray it with 2-4,D just as it is blooming, which is right now.
Height-up to 2 feet on erect stems
Flowers-small, white, in dense clusters
