Last year we had a volunteer Sunflower come up in the yard under a stand of Oak trees. It was about six feet tall, slender stalk and had a beautiful bloom that you can see if you click on the link above. This year we had one come up near the house. It is about three and a half feet tall with a thick stalk. The blooms are similar. It has been fun watching it grow and the bees are enjoying this early bloom very much.
