I have the same "tree" in the ditch as the original picture in this post and I think the leaves look sumac-like. The hogweed has fern-like leaves. Based on that, what do y'all think we have here with the Queen-Ann_lace flowers and Sumac-like leaves?

Definitely a zinnia.

I found the name: Pearcea hypocyrtiflora Here's a link with more pictures: http://www.gesneriads.ca/pearcea.htm This diminutive rhizomatous plant has very attractive and colorful foliage, as well as unusual brilliantly red flowers. The lobes of the flowers do not open except under optimum conditions. The flowers are probably hummingbird pollinated. They grow in colonies in tropical rain forests.

2nd is a vetch. Both are rather etiolated so difficult to id being atypical in growth. Can you tell us where they are growing geographically?
