Yes, and it is quite a colonizer too.

Don't plant it where you don't want it to make a bigger mass of itself.

There are quite a few selections to choose from as well. Many are yellow/golden yellow, and a few white ones. There is a double flowered golden one as well.

Very green stems make this plant easy to identify. For me, it grows about four feet tall. It has spread/massed in some pretty lousy clay loam soil with no assistance from me, in the shade of Common Hackberry, White Ash, and Black Walnut. In better soils, it will likely colonize more ground quickly.

When it starts looking a little ratty, I just mow it off. It grows right back - again, with no particular assistance.

Here's Kerria japonica 'Pleniflora' at the Valley, mid-April last year.
