Viburnum acerifolium

As Terry says below, the leaves are similar to some Maples, especially Acer pensylvanicum, which I thought this was, until they bloomed.
I've seen some pictures of this plant's leaves with five lobes but the ones I've found here all have three, except young leaves sometimes are unlobed and toothed.
It spreads by shallow runners under leaves on the forest floor.

I discovered one in my woods 2 years ago growing in dense shade. It is one of my favorites now. I would recommend it for any woodland garden.

One of the most shade tolerant of the viburnum genus, mapleleaf viburnum is a widely distributed native understory shrub in KY. Flowering and fruiting more heavily with more light, it is still stalwart and handsome under closed canopy forest. The pinkish (and into the palest purple) fall color is quite handsome in the fall, and unique for shrubs around here.

It is so easily grown, it ought to be a staple of any native gardener's palette where it is hardy.

I agree with a previous author--maplewood viburnum are hardy in zone 4. I have never planted any, because the birds have done that for me and the plants are thriving nicely. Fortunately, the birds planted the seeds in a fairly wooded (natural as possible) area, and they are nicer than the poison ivy also planted by the birds.

This species hardiness is from zones 4-8, not 6-8 as listed in the description

Mapleleaf Viburnum has bright green or dark foliage in the spring, turning a pink to maroon color in the fall. Leaves have five lobes, similar in shape to Maple leaves. Late spring flowers are white, forming flat clusters, turning to purple or blue-black berries in late summer.

Can tolerate deep, dry shade.
