What Plants Reproduce Without Seeds?

Not every plant relies on seeds to reproduce. There are many that do so asexually, needing neither pollen nor any of the other means by which plants such as beans find necessary to multiply. Some plants proliferate by using rooting methods while others merely need a surface to attach their roots to and march across on their merry way. Gardeners benefit with free plants, or despair with out-of-control varieties that aggressively choke out other plants around them.


People are drawn to bamboo because of its sleek, bright green tubes that are associated with the tropics and Asian-inspired furnishings. Bamboo is even becoming more popular as a sustainable material for wood flooring. But its aggressive growth, enhanced by its underground, thick-stemmed rhizome system, means it often spreads rapidly to unwanted places. When confronted with an underground barrier, the rhizomes will simply turn and go around it in whatever direction it chooses, including down. The American Bamboo Society suggests placing a bamboo barrier at least 30 inches deep, or to create a shallow trench about 8 to 10 inches deep, around each planting. Check regularly for rhizome spreading in the summer and fall, and cut off any wayward spreading.


Iris also spread via rhizomes, but not nearly as prolifically as bamboo. Plant rhizomes with clipped roots and leaves in a spot that receives full sun and in light, well-drained soil that has been tilled at least 10 inches deep. Within three years the rhizomes will begin to crowd each other out if plants are spaced 1 ½ feet apart. Dig them up about one to two months after the plants bloom and divide them by cutting the older rhizome away from the new and replanting the new portion.


These yellow and white spring flowers grow from bulbs. Plant them in late summer or early fall, before the ground freezes, in well-drained soil and in a spot that receives full sun. Plant them so that the pointed top of each bulb is at least two times as deep as the bulb's length. Allow the foliage to yellow before cutting it back after the flowers bloom. Control the spread of daffodils by digging the bulbs up each spring, rinsing them, letting them dry a week and then storing them in a cool place before planting them again in the fall.


Strawberries reproduce asexually above ground by stems, called stolons, that reach across the soil and take root and create another plant. Grow cultivars that will do well with your specific soil conditions, particularly those that are well-drained, sandy and high in organic matter. Plant them in full sun and ensure the plants have up to 1 ½ inches of water per week. Pinch off flowers the first year to promote "runner" plant formation and rooting before late summer. To prevent overcrowding and promote multiple crown development on plants that are retained, cut additional runners after there are five plants per square foot.
