thanks silver surfer, it looks exactly like the photos for a milk thistle - I wished I had it, it's in a relative's garden, where it self seeded - this was a quick id - great!
hanna. Be very careful. it is listed as a noxious weed in some places. Good pic here! http://commons.wikimedia.org/wiki/File:Silybum_marianum_001.jpg
