There are many plants that don’t flower, including some of the most common and well-known plants such as ferns, mosses, and algae. These plants are called cryptogams, which means “hidden reproduction” because their reproductive organs are hidden away or not easily visible. Some other examples of plant life that don’t flower include horsetails, liverworts, and hornworts. While we often think of flowers as being the showy part of a plant that attracts pollinators like bees and butterflies, not all plants need or use flowers for reproduction. In fact, many cryptogams reproduce via spores—tiny cells that travel on the wind or water to find a new place to grow into a plant.
