Asexual reproduction is the type of reproduction that does not involve fertilization by another organism. Many plants that reproduce asexually produce seeds or spores that can grow into new plants once they find suitable soil. Other methods of asexual reproduction are the formation of plant-lets on specialized leaves, the spreading of rhizomes, the formation of new bulbs or tubers, or producing adventitious shoots and suckers on the plant's lateral roots.
The iris (Iris albertii) is a perennial herb. It produces a showy flower that blooms in the spring. The blooms come in a wide variety of colors including purple, red, orange, yellow, white and blue. Irises reproduces from both seeds and rhizomes. The rhizomes should be separated from the plant after the flowers have died away by loosening the dirt around the base of the plant and gently pulling the new bulbs away. These bulbs should be planted about a foot apart so they can spread and produce new blooms. Irises prefer full sun or partial shade and well-drained soils. They can tolerate drought conditions and should be planted in late summer or early fall in order for them to bloom the following spring.
The day lily (Hemerocallis) is a perennial plant that reproduces by re-seeding. The average day lily grows to 3 feet tall and blooms from early spring to late summer. They vary in color, with popular hues including yellow, purple, magenta, pink, red, yellow and white. Day lilies grow in clusters of four to five flowers. The flower is very hard to get rid of once it establishes itself and can become invasive with its runners. Divide the runners in late fall. Pry the roots apart in groups of two and replant them a foot apart. The new runners will produce plants the following spring. The plants prefer to be planted in full sun to partial shade and well-drained soils.
The common strawberry plant (fragaria) is a perennial fruit that reproduces through its runners. It is a low-lying plant that usually does not get more than 6 inches tall. The flowers are white with a yellow center and they bloom early in the spring. The fruit is produced in early summer and is bright red. Strawberries prefer full sun and well-drained soils. They are easy to grow and spread very quickly. The runners of the strawberry plant produce new roots which make new plants. The new plants grow fruit, which send out more runners. The original plants will begin to decline in fruit production by the second year and are replaced by the new runners.
The dandelion (taraxacum) is a perennial, herbaceous plant that grows on a long stem. It reproduces by means of spores. They bloom nearly year round in temperate areas with a small yellow rosette-like flower. The flower matures into a puff ball of seeds that is carried by the wind. The flowers reproduce when the spores take root in surrounding grass. The spores are fertilized by the soil and new flowers are produced. Dandelions are considered weeds in lawns because they can multiply quickly. They can tolerate a wide range of conditions, even drought. Dandelions prefer full sun and moist soils.
