I had some tall plants with bright yellow flowers to come up in my clover. These plants get about 6 ' tall and spread at the top . May have 12 to 15 bright flowers on them. I don't know what they are. I went down to Statesboro today and saw a lot of the same plants along the fields and in fields. Some one throw out some names and I'll look them up. I have already looked in my references book and couldn't find them. I don't recall ever seeing this plant before.It may have been in the clover.
