What is Sexual Propagation?

Sexual propagation is the creation of a seed through the pollination of the female part of the flower by the pollen of the male flower. The most common and least expensive method of propagating plants by far is from the seed. Flowers are beautiful to look at but their ultimate purpose is to produce seed to perpetuate their species. Seeds become fertilized embryos when the male pollen from the stamen pollinates the female pistil part of the flower. When the right conditions for light, oxygen and temperature are met, the seed will come out of dormancy and begin to grow. Not all seedlings are exact duplicates of their parents, but variations might be able to adapt and survive better. To propagate a seed successfully it is essential that the conditions be right. Temperature, humidity, light and oxygen and carbon dioxide supply must be favourable to ensure germination. Each kind of seed has specific requirements for germination. Some seeds must be frozen prior to planting, some like a very moist environment while others prefer very dry conditions. For most common seeds the growing medium, in which propagation is to take place, should be sterile and supply plenty of oxygen while retaining moisture. As the temperature gradually warms and spring officially arrives, you will probably be spending as much time outdoors as possible enjoying time with your new plants. Whether they were born from seed or vegetative clones, there is nothing more satisfying than playing a part in the procreation of the very thing that makes gardening possible, the plant
