Sunflower flourishes well under well-drained moist, lime soil. It prefers good sunlight. Domesticated varieties bear single large flowerhead (Pseudanthium) at the top. Unlike its domestic cultivar type, wild sunflower plant exhibits multiple branches with each branch carrying its own individual flower-head. The sunflower head consists of two types of flowers. While its perimeter consists of sterile, large, yellow petals (ray flowers), the central disk is made up of numerous tiny fertile flowers arranged in concentric whorls, which subsequently convert into achenes (edible seeds).

It's also great at sucking up lead. I wouldn't grow it in your garden to eat in this region.
