A native, perennial, tap-rooted wildflower with showy, yellow ray flowers and reddish- brown central disk flowers. These short-lived perennials are usually planted from nursery starts, but they also grow easily from seeds planted directly in the garden after the last frost date (or started indoors about 4 to 6 weeks early).
Pollination occurs by insect, bird, wind, humans, or other natural mechanisms. Because there are no restrictions on the flow of pollen between individuals, open-pollinated plants are more genetically diverse. However, as long as pollen is not shared between different varieties within the same species, then the seed produced will remain true-to-type year after year.
Perennial plants live for more than two years. They return year after year and continue growing until they reach maturity, which varies by plant but averages three to five years.
