I have no trilliums in my garden - yet. I say yet because soon I'm going to have to have one - or more! These bright white native wildflowers naturalize, which is great news. But I confess I didn't know what this was when I came upon it in the woods. Spring ephemeral, yes. Wildflower, yes. But which one?
Trillium grandiflorum, the big guy. It's perfection, love those three petals, great for shady spots. Two things in the negative column. No fragrance -- :( -- and while this doesn't affect me, it does a lot of gardeners in the area: deer love it.
