Non-seeded plants are much less common than those with seeds. As you look around, most of the plants you see create some sort of flower or bud. These blooms create seeds, which are transferred, whether by nature or man, to create more of their kind. Though seedless plants do not create seeds, they are still able to reproduce, mostly by the creation of spores.
Ferns are vascular plants that have waxy coverings. One of the most common seedless plants, ferns can grow to vast sizes, up to a yard tall. Like most seedless plants, ferns produce spores that are dropped from the fern to the ground for reproduction. Most ferns produce spores in sets of four and produce billions of spores during their lifetime. Although a large amount of spores are dropped, only a few spores find suitable growing locations before they cease to exist. These plants require abundant amounts of standing water and some light to reproduce. Ferns are easily cared for and develop their own natural fertilizer using bluish-green bacteria within their leaf system.
Moss is a seedless plant that has no true roots. Moss grows naturally on wet rocks, damp tree bark and in and around muddy ponds and streams. It appears as a fuzzy, green carpet and has no stems or bark. Moss requires a firm, acidic soil bed, complete shade and abundant moisture to sustain life. This plant's preference for acidic soil provides it with the ability to balance the soil's chemical balance, improving overall plant growth in the area. Moss can slow decay of matter and prevents many disease-causing bacteria.
Liverworts are seedless plants that have flat, leathery foliage. The ribbon-shaped plant grows in very moist areas and often appears on surfaces of still water. Still, liverworts can appear in all climate variations and grow in dry places and submerged aquatics. This plant has no woody structure and prefers deeply shaded areas. Liverworts' history shows that it is one of the first plants on earth and is often referred to as "the simplest true plant." It reproduces asexually.
Like ferns, horsetails are vascular, seedless plants. Though they are quickly becoming extinct, horsetails can be found in all climates and temperatures. These plants have tough exteriors and produce a silicon-based compound in their epidermal cells. Many horsetails are of woody variations with stems that reach vertically from a base and reach heights that average those of postmodern conifers. Though horsetails are flexible to soil type, they prefer damp, partially shady area. They reproduce using spores that are dropped or fall from the tree into suitable germination areas. Horsetails are known to be toxic to surrounding vegetation and can be difficult to rid of once they have established ground.
