ANNUAL: Annual Sunflower can sometimes survive in the Sonoran Desert for
more than a year if moisture and lack of killing frosts are favorable. With
good moisture plants can exceed 2 m in
height. Branching freely.
Birds and insects of many kinds use annual sunflowers as a food source. Many
kinds of bees and flower-loving flies are attracted to the flowers. Rover Ants
and others take nectar secretions and may work to protect the plant. A large
leafhopper, the Smoketree Sharpshooter, and lace bugs take sap from the phloem
tissue.Click a thumbnail for more information about these sunflower associates.
