Last March I became infatuated with an acid green weed growing in the cornfield adjacent to my parent's place. I dug a few clumps and planted some in my mom's garden and some in my own. I knew it was some sort of Euphorbia, but was unsure as to the exact species. Fellow blogger Entangled suggested it may be Eurphorbia helioscopia (Sun Spurge, Madwoman's Milk), and I am now pretty sure that identification is correct. This species is a winter-blooming annual native to Europe, North Africa and Asia, and is apparently now quite at home here as well. Further reading on this plant told that although it is considered poisonous and a carcinogen, its extract is used medicinally and is easily found for sale on the web. My clump had whithered by late April of last year, and I thought that was likely the last I would see of it. This week I noticed about a dozen separate plants coming up in the hell-strip, not far from where my clump was planted. So it looks as if I have introduced this weed to my neighborhood. I am sorry neighbors!
Here is another reminder that my Winter Walk-Off 2012 is going on until Monday the 19th. All bloggers are welcome to join in.
