The calyx is aposepalous with 5 [3–6] imbricate sepals. In some plants, where vegetative reproduction by natural means is difficult to occur, special techniques can be used. A stimulation of adventitious bud and root formation was affected when leaf discs of Streptocarpus were excised from stock plants subjected to a cold period (12 °C) before leaf harvest (Appelgren and Heide, 1972). Answer: Begonia and Bryophyllum are examples of vegetative propagation by leaves. When the buds drop off from the leaf and placed in soil, they develop into new plant with roots and small leaves. No garden soil or other uncontrolled soil choice should be used with the cuttings since even the smallest pathogen destroys sensitive plantlets and root outcrops.

The Begonia hybrid groups most often used for commercial flowering potted plant production include B. × cheimanta ‘Everett’ (Christmas begonia or Lorraine begonia), B. A particular group of begonias, called the rex begonias (Begonia rex cultorum), propagate themselves through leaf cuttings. In time, these plantlets fall off the leaf and establish themselves as new plants. The growing medium needs to retain moisture, without becoming soggy, and air pockets must abound within the soil-less mix so the cutting has proper air circulation. Many plants, such as the succulents, Bryophyllum, and Crassula, Mexican Hat plant, Begonia, Saint-paulia, reproduce vegetatively by producing small plantlets with leaves, stem, and roots along leaf margins (Fig. Let us explore the different types of vegetative propagation and its examples in detail.
