Here's one to stump you all... (no pun intended)

digisonJuly 8, 2014

It came up in the spring with other weeds, but this didn't look like normal weed- more like a tree. It's a new house, so lot has been disturbed, so it may have been a dormant seed. Or, I mulched with forest mulch around here, so it may have come from mulch. Someone on another website suggested some type of euphorbia. One of seedlings I pulled up had a fat root on it.

Could be some escaped Euphorbia pulcherrima aka Poinsettia! My friend has some naturalized in her yard here in Tucson.

I take it back, she has E. cyathophora, Mexican fire plant, rampant in her yard. Could you take a closer picture of the growth tip, which may show a small inflorescence?

If you pull a leaf off, does it bleed milky sap?

(If it does, wash your hands well. The unlucky folks sensitive to the latex sap in Euphorbia plants can get a rash from it, on par with poison ivy.)

Doesn't seem to be any milky sap. Would that rule out a euphorbia?
