Popping up everywhere. Think it was in the pine straw mulch :(
Looks like Poison Ivy and some other weed
Possibly, or Virginia creeper (Parthenocissus.)
Yes, one or the other. Sometimes Virginia creeper pops up with 3 leaves on the first true leaf and then has 5 on the next set.
Cotyledons match Vitaceae.
Yes I agree that Grape seedlings start out that way too, until you get to the true leaf.
Right, I was confirming Parthenocissus rather than Poison Ivy.
Oh I see what you mean. I actually had not realized that Parthenocissus was in the Vitaceae family. Learn something new every day! :)
