The Black-Eyed Susan is a wildflower that grows in the eastern part of the US. The Back-Eyed Susan can grow up to 2 to 3 feet. It has a brown dot that is surrounded by bright yellow petals. Another name for the Black-Eyed Susan is Asteraceae. The flower grows between June through August. The type of soil it grows in is top soil and it likes to be in the sun. The best place to plant, is on the road side. An interisting fact about it is, it is the most common wildflower in the US. I think the Black-Eyed Susan is a fasinating wildflower.
