There are 150 species of sunflower, including H. annuus, the giant sunflower from which we get seed and oil; and H. tuberosum, the roots of which form Jerusalem Artichokes. All species are tall and many can be invasive, but their bright yellow summer and fall flowers make up for any inconvenience.
Wildlife Value: It is a great late-nectar plant for butterflies. Birds are attracted to seeds so leave standing dead flowers into the winter as natural bird feeders. Members of the genus Helianthus support the following specialized bees: Andrena (Callandrena s.l.) accepta, Andrena (Callandrena s.l.) aliciae, Andrena (Callandrena s.l.) helianthi, Melissodes (Eumelissodes) agilis, Dieunomia (Dieunomia) heteropoda, Megachile (Sayapis) pugnata, and Paranthidium (Paranthidium) jugatorium. This plant is occasionally damaged by deer.
