Sure, here's info from About.com to tell the difference. But, Doris, we love your pictures, lilies or daylilies!
Daylilies:
"Foliage: The leaves are a dead giveaway as to which plant you have. Daylilies have long, flat strap-shaped blades that grow in clumps from the crown of the plant, at the soil line. Daylilies grow from about 1' high up to 4'.
Flowers: Each flower is in bloom for only 1 day. The name Hemmerocallis comes from the Greek words "hemera", which means day and "kallos", which means beauty. Most plants have multiple buds that will bloom over a period of time.
The flowers are borne on thin stalks, or scapes, that grow from the base of the plant. The scapes may be multi-branched.
If you look closely at the flower, you’ll see that 6 petals are in two layers of 3. The top three are the actual petals. The bottom three are sepals. The center of the flower, the throat, is often a contrasting color."
Lilies:
"Foliage: There is one central, unbranched stem from a lily bulb, with the flower buds forming at the top of the stem. The leaves grow around the entire length of the stem, in whorls or spirals. Lilies can grow from about 1 ½' tall to a towering 10'.
Flowers: Lilies always have 6 petals and 6 anthers. Each bloom lasts a week or more. The lowest buds on the stem will open first and the remaining buds will open sequentially through to the top most buds.
Lilies flowers also come in a variety of forms, includeing: trumpet-shaped, bowl-shaped, funnel-shaped and recurved. "
