A very popular flower this time of year (for fall and UT football) is the orange Asiatic Lily

Asiatic lilies are sometimes called love lilies and can be white, purple, pink, magenta, red, burgundy, peach, orange, or yellow. The orange and yellow are very popular this time of year. There are 3 to 5 flowers on each stem. As with most lilies it is important to make sure as the buds open that you remove the anthers that contain the pollen to prevent staining.
