June, in regards to your query...Sunflowers have been self-seeding here since 2004 when they were originally planted to provide shade to two new Paw Paw tree seedlings (forest understory tree that needs shade for first couple of years to survive). Original cultivar of sunflower was Kong, a multi-flowering giant of 12 ft tall (or taller). Goldfinches love them, Cardinals sometimes visit as well.
