Helianthus annuus is an annual that is native to the Americas. It grows 6 to 12 feet in height and has hairy oval or heart shaped leaves and hairy stems. This common sunflower requires full sun and is drought tolerant. I haven't grown sunflowers from seed in a long while, but there have always been a few sprouting in the yard for the past few years, compliments of the backyard birds! I don't know anyone who doesn't like the sunflower. If those big, beautiful heads of flowers don't make you smile, I don't know what will.

Each year I like to grow some sunflowers in my garden. They actually self seed, so I can just leave a few plants where I want them. I grow them not only because they are pretty, but also to attract the backyard songbirds. As soon as the flowers start to get ripe seedheads, goldfinches arrive to eat them. They will keep coming as long as there are seeds for them to pluck. So if you want to attract goldfinches, grow sunflowers, which are an excellent alternative to a feeder.

Located on Long Island, NY zone 6/7, where it is humid in the summer.

Honey bees get golden pollen from this plant. Also a reliable source of hnoeydew.

"The sunflower (Helianthus annuus) is an annual plant native to the Americas. It possesses a large inflorescence (flowering head), and its name is derived from the flower's shape and image, which is often used to depict the sun. The plant has a rough, hairy stem, broad, coarsely toothed, rough leaves and circular heads of flowers. The heads consist of many individual flowers which mature into seeds, often in the hundreds, on a receptacle base. From the Americas, sunflower seeds were brought to Europe in the 16th century, where, along with sunflower oil, they became a widespread cooking ingredient. Leaves of the sunflower can be used as cattle feed, while the stems contain a fibre which may be used in paper production.

To grow best, sunflowers need full sun. They grow best in fertile, moist, well-drained soil with heavy mulch. In commercial planting, seeds are planted 1.5 feet apart and 1 inch deep. Sunflower "whole seed" (fruit) are sold as a snack food, raw or after roasting in ovens, with or without salt and/or seasonings added. Sunflowers can be processed into a peanut butter alternative, sunflower butter. In Germany, it is mixed with rye flour to make Sonnenblumenkernbrot (literally: sunflower whole seed bread), which is quite popular in German-speaking Europe. It is also sold as food for birds and can be used directly in cooking and salads. American Indians had multiple uses for sunflowers in the past, such as in bread, medical ointments, dyes and body paints.

The sunflower is the state flower of the US state of Kansas."

Helianthus annuus is a larval host plant for the Spring Azure, Silvery Checkerspot, and Painted Lady Butterflies.

According to the NPIN, this plant has special value to native bees while its seed heads attract a wide variety of birds.
