Gardeners' Notes:


On Nov 2, 2011, FlyPoison from Rock Hill, SC (Zone 7a) wrote:

I made the mistake of allowing this invasive plant to bloom and let the flowers dry, resulting in a heavy seed dispersion on the edge of my woods. The flowers are a pretty purple color and the plant itself can only be handled with gloves due to it's very spiny skin. It can grow to 6' and doesn't seem to attract anything more than bumblebees here. In wild settings it seems to be less successful.

A former First Lady of Illinois pushed to naturalize the land along state roadways. It was a win-win for tax payers since naturalizing saves costs associated with mowing miles of highway an interstate. Musk Thistle is one of the big beautiful flowers seen here. It provides necter and is photo worthy as a bud and in bloom.

One man's weed is another man's flower.

"Ecological Threat:
It generally does not pose a threat to high quality areas. It colonizes primarily in disturbed areas.
Musk thistle is distasteful to grazing animals, giving the thistle a competitive edge.
It grows best in disturbed areas such as pastures, roadsides, and ditch banks, but also in hayfields and disturbed prairies.
A native of western Europe it was introduced to the U.S. in the early 1800s, and is declared an agricultural pest.

I was driving a back road one day and noticed a government vehicle driving slowly in the opposite direction. There was a man riding shot gun spraying these things that grew on the side of the road.
My property was once a cattle grazing land and I get these growing in my lawn. If given the chance they will creep into a flower bed or fence perimeter. I try to pull them from the root with heavy rubber gloves on. They have a long tap root.
Unfortunately, bees and butterflies love these guys.
