It looks like something in the lily family, so it might be a jewel. I would definately keep it for now. I'm thinking it could be the growth of a young Smilax glauca, but I'm not familiar with that species, and the leaf shapes seem a little off for that one. What's the other plant with the wide leaves? It looks a bit like Skunk Cabbage. Whatever it is, it surely won't conquer the planet and break into and vandalize your home.

Thanks, Jay. I was thinking it’s some kind of lily too. The plant with wide leaves at the bottom of first photo is a young foxglove plant. Here’s a closer pic of the one in question —

Do you think it could be Maianthemum canadense?

eta: I looked up Smilax glauca and have never seen anything like that around here.

Maianthemum canadense was my first thought when I saw it this a.m. but I was not convinced. I will look at mine tomorrow.

Ive been wanting Canada Mayflower ever since I learned about it. The leaves seem to match, but the leaves aren't perfoliate, but they might be younger plants putting up leaves and not at flowering stage yet. That was the same issue with the other thread about Maianthemum stellatum. Maybe perenn-all can answer that question about petioles.

My experience of Canadian mayflower is that you get plants much more spread out than that. I have a leaf here, a leaf there, never a clump of leaves together like that, even with a fair amount of spread.

Given a choice of Maianthemum canadense and hosta, I'd go with hosta.

My hostas are thugs. They don't volunteer, but if you dig them out, they come back anyway for several years.

Nice pics Dave! I'd say the leaves are clasping and not perfoliate. Did you notice any fragrance? Gee I wish some would just show up in my yard.

I am leaving this plant to grow for now and see what it turns out to be. I will be *astonished* it it's a hosta.... it doesn't feel anything like a hosta leave texture. This area was my raspberry patch many years ago -- before it got too shady. Now it's an area for compost bins/piles and where I sometimes plop extra plants. :) I do grow several dozen varieties of hosta, but I generally don't let them go to seed, and the two hostas that are nearest to this spot are Abiqua Drinking Gourd and Sagae, and they're each as least 5 feet away.

Ken, this side of the yard is the last in my cleanup rotation and I’ve just barely started, but yesterday I found a missed flower stem on my Elegans hosta that’s at least 10 yards away…. it had clearly set and released seeds last season. That’s another large wrong-colored candidate as a parent to my unknown plant, but it does confirm that the occasional hosta seedpod does get out there from my gardens…… and I have plenty of small hostas too. :p
