Here are the top 10 worlds worst weeds, some I recognize...number 1 is nutgrass,
2 is windmill grass, 3 is barnyard grass, 5 is paspalum grass, 6 Johnson grass, 7 is Blady grass, And 10 is Fat Hen. Then there's CockGrass or Cheat grass or the smooth rye grass that mimic's wheat and becomes the worst weed with wheat.
My question is where do weeds come from? Are they just normal plants taking advantage of a man made habitat ?
These are all flowering plants, so at the earliest, their last common ancestor was a bit over 200 million years ago. Bermuda is commonly cultivated in lawns in the southern U.S., and Mrs. Barbarian raises purslane in her front garden it's quite heat and drought resistant, and has beautiful flowers. Edible too. In much of Europe and Asia, it's used as a vegetable.
Purslane seems to have been distributed around the globe by humans. Cheatgrass originated in the same area as wheat, in western asia, and seems to have been carried with wheat farming cultures around the world.
Not familiar with the others. Is there point?
