1happyhiker, that's an early shoot - the two "petals" are cotyledons, the modified leaves that store nutrients inside a seed. (Take a close look at a chickpea - it splits easily between the two cotyledons, and the joint between them is a tiny stem that will grow a root at one end and a shoot at the other.) In some plants, the cotyledons expand into a "baby leaf" pair that doesn't resembe the adult leaves. (The root grows first and lifts the cotyledons out of the ground, then the cotyledons enlarge.) That might be what your'e seeing here, except that those cotyledons don't look like they've changed shape much. I'm assuming those are normal-sized beech leaves in the background, so that's a good-sized seedling. Maybe it was a pretty big seed (nut) to start with. I could probably find it if I started googling for beech seedling, oak seedling, hazelnut...
The reddish stuff with rough edges will become adult-shape leaves.
Meanwhile, in the Boston area, I'm learning how to use flash to make the background seem dark so that flowers stand out:
but natural light is still useful:
