Especially common are various forms of vegetative propagation among plants living in harsh climatic conditions – in the polar, alpine and steppe regions. Unexpected frosts on a summer day can destroy flowers or immature fruits of tundra plants. Vegetative propagation allows them not to depend on such surprises. Some saxifrages and the highliving viviparous are capable of forming brood buds that spread like seeds, bluegrasses form small daughter plants in inflorescences in place of flowers, capable of falling and rooting, and the meadow core reproduces exclusively by modified segments of pinnately dissected leaves. With artificial vegetative propagation of plants, a person uses all types of vegetative propagation found in nature. However, there are additional special methods: leaf cuttings, dividing the bush, layering, grafting.
