Weed of the Week: Western Wallflower

By: Sherri Roberts, Regional Crops Specialist, Weyburn 

Western Wallflower is a member of the Brassicaceae or Mustard family. It is a biennial/perennial herb that is native to North America and prevalent in Saskatchewan. All leaves are densely covered in short, star-shaped hairs and can give a gray-green appearance. Stems are rough-hairy, angled, may be multiple from the base and are mostly unbranched except in the flower.

Western wallflower gives off a gray green appearance as its stems are covered in dense, short, star shaped hairs. If you examine the stems, you will find them to be rough and hairy with an angular shape. The mostly unbranched stems may or may not be multiple stemmed from the base except in the flower.

There are multiple varieties of wallflower and since E. asperum and E. capitatum ranges do overlap, they will hybridize.

You will find that plants flower from early spring to mid-summer.  Numerous yellow flowers will be present, and can be identified by each having four petals arranged in a basal rosette. Alternating leaves are arranged around the stem.

Western wallflowers are often attacked by fungal and bacterial diseases. Of interest to farmers is that they are also susceptible to clubroot.

Western Wallflower (Erysimum asperum) is also known as: präriekårel, prairie rocket, Pursh’s wallflower, Rough Wallflower, Siberian Wallflower, Diné bizaad, Azeeʼ łahdiltʼéii, Â ffurf gywir, and Argymhellwyd.
