Did she say anything about how big they got? Height, spread, or length of leaves. Are those babies or fairly well grown? My first thought was some type of cactus but
It could be other things. I really have no idea.
I have no idea how invasive that might be. You might try potting some up to keep it alive. You can always send a photo to your county extension office and get them to ID it if we are unsuccessful. Your cover story is that a friend in Boise offered to send you one but you don't want to take it until you know it is not invasive or protected.
Haven't lucked out as of yet, I posted this in a couple of different forums. The forum I usually get a quick response, nothing yet. The other forum I got a rather rude response, which really surprised me. Not being one to rise to the bait, my response I believe was quite civilized being Canadian that's how we are, but only until you push THAT button. Although I have to admit my tongue is still smarting from having it between clenched teeth.
Won't repeat what this person said, obviously this person thinks Canadians are ignorant, uniformed and unlawful. I think I made my point (in a nice way of course) and ended my response with have a nice day.
I was just asked by someone else there if there's any way you could get a better picture, like a closeup of a single plant, it would really help. I'll pass on the additional information and see if we get any bites.
