Locoweed is a common but inaccurate name for 
  jimsonweed.  My browser found a lot of information on 
  jimsonweed. 
   
          
      I believe this information is inaccurate---I KNOW 
  jimsonweed (aka Datura)--I have lived with it for many, many years---no animal 
  that I know will touch it.  We never worried about it for that 
  reason. It looks a great deal different from locoweed (as I knew in 
  Kansas and here in Texas).  Locoweed is a totally different plant and 
  horses will eat it when green stuff is in short supply.  Jimsonweed 
  has a very large kind of oak-like leaf, with whitish trumpet-shaped flowers 
  and large green fruit about the size of an apricot--covered with spikes.  
  It grows to about three feet in height.  The "trunk" can be 2-3 
  inches in diameter on a good-sized one.
      I had some locoweed at one 
  time---and a drought--and looking back I feel a mare ate a bunch of it as she 
  had a deformed foal that fit the description of birth defects caused by 
  locoweed.   
     Also--I have not had any 
  locoweed in the pasture since I got goats.  I also have no more 
  cockleburs--the goats eat those, too.  Nothing eats the 
  jimsonweed.

    Kinda funny Kinda sad. 
    I Was searching for some picks of Loco Weed to give to my new to horses 
    neighbor, And guess what? A whole long list of things about Marijuana came 
    up. Says something about how times and our culture have changed in the last 
    50 years. When I was a kid, if you mentioned LocoWeed everybody knew you 
    meant crazy horse weed. But now, I had to look for quite awhile to find the 
    sites I wanted. I did fine very little, Does anyone know where I can find 
    good pictures of LocoWeed( not Canabus) ((  I don't even know how to 
    spell it! )) I know there are a few varieties, I only found one. 
    Thanks.Annie
