Nearly a tree in one short season.
From a tiny seed to a 12' tower in just one season: giant sunflowers such as these are vessels of unrestrained garden joy, metaphors of garden power. Domesticated by Native Americans, pre-Columbus sunflowers were smaller and bore fewer seeds than those we know today. It wasn't until the 1500s that sunflower seeds made their way to Europe, eventually arriving in Europe, where they were selected for their size, oilseed production, and beauty. A tall plant with a deep history!
