This plant started growing this spring in my back yard in Arizona. It is now a few months later and the plant is about 4 feet tall.

Can someone tell me what this is?

  • It's a weed, or a wild flower, depending on your point of view; can't remember its name, but anything that grows that fast is usually a weed. If you planted wild flower seeds at some time, it may have been in the mix. Hopefully someone else will remember its name... – Bamboo May 26 '17 at 16:38
  • Do you remember any flower on this guy? I think Bamboo is right that this was part of a 'wild flower' garden. Couldn't find an Arizona weed to match. My guess is Penstemon...but Aster just might...why did Diane's answer get 'deleted'? – stormy May 26 '17 at 20:55
  • Did not see Diane's answer. As to wild flower i hope it looks like either you mentioned. No colors yet just the green leafy stalk. – Bob May 26 '17 at 23:04

This appears to be a healthy horseweed (Erigeron canadensis). A noxious, roundup resistant, drought resistant annual weed. They can produce over a million wind dispersed seeds per plant, and the seeds can persist in the soil for a long time.
