Flowerless plants are a type of plant that do not produce flowers. Two examples of flowerless plants are ferns and mosses. Ferns are a type of vascular plant that reproduce through spores and have fronds that are divided into leaflets. Mosses are small, non-vascular plants that reproduce through spores and have stems and leaves. Both ferns and mosses are found in moist, shady areas and can be used to decorate gardens.
