Oh yeah. I am not one of those people who goes around mowing everything mowable — that is so Midwestern— but this year I mowed one little meadow that I had not touched in twenty years, because it was sprouting kochia and Russian thistle, the baddies:
In El Paso County, the two chief culprits are Russian thistle and kochia, [rancher Sharon] Pattee says. The Colorado State University Extension labels them both as "troublesome annual weeds of rangeland, pastures, fields, disturbed areas, gardens, roadsides, ditch banks and small acreages."Tumbleweed Christmas trees? Been there, done that. One year when I was little, I was sick in bed during Christmas, so my older sisters decorated a big globe tumbleweed with glass ornaments and put it by my bed.
Both are non-native species. Russian thistle originated in, yep, Russia, and is believed to have come to the United States in the late 1800s through contaminated flax seed. Kochia is from Asia.
This was when we lived in Rapid City, S.D., where they were easy to come by. This year in southern Colorado, every barbed wire fence looks like a fuzzy brown wall. Yeech.
