Daffodils come in many shapes and sizes. Trumpet daffodils feature a cup that is as long, or longer, than the petals, while large-cupped daffodils have cups that are more than one-third, but less than the length of, the petals. Small-cupped daffodils have cups no more than one-third the length of the petals. Triandrus daffodils produce two to six blooms per stem, with curled-back petals and short cups. Go through this wonderful slide show to learn more about different daffodil varieties and how to plant and care for them.
The flowers have a central trumpet (corolla) -- the length varies among cultivars -- surrounded by a collar of petals (perianth) that can be a different color. Colors include yellow, orange, white, red, and peach. Some are fragrant.

Tazetta daffodils always have 4 to 8 fragrant flowers to a stem, with white or yellow petals (perianth) surrounding a shallow white, yellow, or orange cup (corona). The leaves are strappy and a little shorter than the flower stem.
