This seedling volunteered in a wooded, leaf and rock mulched area of our yard. It is in the shade. Our soil is red clay. It is similar to red bud but has different leaves.
this is one of the mulberries, most likely Morus alba, the common white mulberry [the fruits are not always white]. It is not hairy enough to be the paper mulberry [Broussonetia papyrifera], but it could conceivable be the red mulberry, Morus rubra, which is widespread in the Carolinas. Red mulberry has a lot of short hairs on the underside of the leaf, more so than the white mulberry.
