Hi,
I saw this plant growing in a shaded area in a garden. I really like the foliage and was interested in an identification of the plant to see if I could plant it in my garden.
Thanks.

Your photo looks like it could be mustard greens:

I don't think these mustard greens. Mustard greens have slightly different shaped leaves.
The leaves are about 12" by 12". The plant itself is a 6 feet by 8 feet "patch" of plants. Leaf shape is similar to Ligularia dentata but the leaves are larger than any Ligularia dentata I've seen.

Thanks.

Petasites?

That looks exactly like it! Thanks for helping out.

I don't know what plant hardiness zone central Indiana is considered but my first thought was it reminds me of Giant Leopard Plant (Farfugium japonicum var. giganteum) which is zone 7a and higher:

Looking at more photos for comparison, it does indeed look more like Butterbur!

Petasites japonicus is similar but slightly less cold hardy, apparently:
