What are Imperfect Flowers?

Imperfect flowers are flowers that only have one set of reproductive organs, so they are either male or female. There are two types of imperfect flowers. Staminate flowers contain only stamens, the male reproductive part of the flower. Pistillate flowers only contain the pistil, or female, reproductive part. Perfect flowers, on the other hand, such as roses, are flowers that contain both a pistil and stamens, and therefore are both male and female. A third type of flower, the incomplete flower, can be either perfect or imperfect, but is missing one of the four major parts of a flower: the pistil, stamens, petals or sepals. While perfect flowers can reproduce entirely within one bloom, imperfect flowers need two separate flowers in order to pollinate themselves and create seeds.
