A true lily plant is grown from a bulb. The flowers of the lily plant can blossom in one of three ways: through the the raceme, umbel or terminating blossom or flower. The raceme is a series of blossoms on stalks along the stem. An umbel is a series of blossoms that bloom from a single stem. The terminating blossom is one single blossom on a stem. The parts of a lily flower have separate purposes in the pollination process.
The lily blossom, or perianth, is comprised of three sepals and three petals. The six segments are also known as tepals--a term used when the corolla and calyx are not easily noticeable. The sepals--which are at the bottom of the blossom and the inner petals--have the same coloring and markings. A furrow or groove in the base of each tepal leads down into the nectary. Nectar is secreted from the nectary furrow, and entices insects and birds to visit the blossom and dislodge the pollen.
Male Reproductive Parts
Six long filaments branch out of the center of the lily and hold the anthers that are vital to the male reproductive parts of the plant. The anthers are the pollen bearing organs. The filaments keep the anthers up and away from the flower. This allows pollination of other plants to occur with help from the wind if no bees or insects are in the area. Lily pollen comes in a variety of colors according to the type of plant.
Female Reproductive Parts
Deep within the center of the lily you will find the pistil. It houses the reproductive parts of the lily plant. The long slightly curving extension that comes out of the lily throat is the style which holds the three lobe stigma away from the lily blossom. The stigma has a sticky substance that pollen settles on to and stays in place for the fertilization of the plant. Wind, bees, insects and birds can blow or knock pollen onto the stigma. At the bottom of the pistil is the ovary. The ovary is the protective location where the seeds develop and mature.
