Where do weeds come from?

Weeds are plants that are not native to an area. Usually the plant will have gotten from one part of the world to another by humans who wanted cool garden flowers or scientists who wanted to do test and so on. Weeds spread around by way of birds, bats and other creatures eating fruits of a plant as food and then poop out the seeds when they are flying around. Seeds are too tough to be digested and the poop acts as a little packet of fertilizer. And presto, your lawn is covered.

There's this weed that had poisonous spiky hairs on the thick stem, and if manhandled, spreads it's seeds really fast and the hairs can cause tumors in the hands. Also really hard to pull up and the root can grow more plants. And it's in the U.S.! Wyoming!

Any rooted plant does - you could pick an oak tree or a rose bush, or even a marijuana plant if you wanted.\n\nThe roots grow down, toward the center of gravity. The leaves and stem grow up, away from the center of gravity.

So...where'd you get the weed, man?

From the Spanish word "potigauya" which means marijuana leaves.  The term "pot" has been in use in the US at least as far back as the 1930's. \n \nAn interesting sidebar here -- the Marijuana Tax Stamp Acts created in the 30's were part of the federal government's attempts to create marijuana laws to use against Mexican immigrants as well as against African-Americans.   \n\nIn that period, there were significant numbers of Mexican and other Hispanics living in the US, and much like today, there was a great public outcry against them.\n\nOur (US) history is filled with immigrations and cultural backlashes against the immigrants.  My own family began its history in the US as part of the mid-19th century Irish immigration.  The prejudices against the Irish were exactly the same as today's prejudices against Hispanic immigrants.

Far as I can tell, it's weed, garden weed, not the other weed if you're getting any ideas, processed by leeching human blood. I believe that also might have been in the book by H.G. Welles but it's been awhile since I've read it, so I don't know 100%. But why aliens are leeching of our blood to create lawn feed is beyond me.

My parents are having this problem as well.  Their neighbor has weeds and overgrown bushes.  Get your local alderman/representative involved.  If you're in a neighborhood and have a neighborhood committee, I would appeal to them.  That's what my parents did and saw immediate results.

The hairs on weed usually turn red when they are fully matured, meaning that bud with red hairs are usually of high potency, rather than orange hairs for example. Purple weed is exactly that, weed with a purple hue instead of green. Many people are dumb enough to believe that if its purple, its amazing, WRONG. Many strains turn purple just because they do, and others turn purple because the temperature around them was somewhat cold. Look at alot of green plants during fall/winter, some will start to turn purple, this is true with clovers. Skunk is just specific strain of weed. It should smell rediculously strong and more pungent than your average bud. Yet again, this doesn't mean its good. It could still be garbage.

Salt comes from  dissolved rock. Rivers carry that salt from the land to the ocean. It's that simple.

Check by visiting the website lists of reputable seed companies such as Thompson and Morgan. Any restrictions on the supply of seed to specific countries will be posted there.  I can't imagine why Canada would choose to proscribe this plant, in the UK it is a common  native weed  but not invasive or an ecological threat.\nWhy would you want to grow it anyway? I spend too much time pulling it out!

A weed is a "plant out of place." "Noxious weed," "pest plant," and "invasive species" all have legal definitions, but a "weed" is a subjective term. My dad went through the same angst when nightshade popped up in his yard--I said hey, keep it, it's pretty (and you know not to eat it). But my stepmom thinks the berries are staining the deck...it's all perspective.
