Do sunflowers come back every year?
While most varieties of this bright beauty are annual sunflowers, meaning they will not come back the following growing season, they may self-germinate from dropped seeds if you leave the heads on the plants throughout the winter. The perennial Maximillian sunflower features small blooms in late summer and early fall.
