I missed the flowers, but here's the leaf. I'm in VA and it's growing in the shade mostly.
Looks like Arum italicum.
I have that in my shady front yard, too (or hopefully not, as I just weeded it out). They are also called Italian Lords and Ladies.
I was going to tell my interested kiddo about the funny name, but then realized the first thing out of her mouth would be "why is it called that?" so I got to thinking hmm...well the flower looks very vessel-like (ladies), and the seed stem kinda looks like (OH!) ok, nevermind...she doesn't need to know about that.....LOL
