The process by which blossoms become seeds is called pollination. Plants reproduce in this way. Self-pollination and cross-pollination are the two primary types of pollination. The movement of pollen from a stamen to a pistil within the same plant is known as self-pollination. This may occur within a single flower or between several flowers on the same plant. Pollen is transferred from one plant's flower to another plant's blossom through a process known as cross-pollination. Carriers are necessary for cross-pollination in flowers. Pollen is transported by carriers from one plant to another. The wind, insects, birds, and other animals are among them. Fertilization takes place on the pistil of a flower when a pollen grain touches it. In other words, a sperm cell from the pollen gets inside the pistil's egg cell. The The hybrid tea rose originated from a cross between roses and hybrid perpetuals. It has become the most widely grown rose variety worldwide due to its massive blooms and active, long-lasting flowering behavior. Natural hybridization between R. chinensis and a damask rose on the island of Ile Bourbon, today called the Island of Reunion, close to Mauritius, gave rise to the Bourbon rose. Before the Suez Canal, it was a crucial port of call for French ships resupplying. Early in the 19th century, a hybrid seedling was sent from that location to Paris, where it underwent additional crossing with R. gallica. The resultant roses are still commonly grown today because of their powerful aroma and lengthy blooming season. Hybrid teas were the first type of modern roses, and grandifloras and floribundas quickly followed. The former were grown in the late 1800s by the Dutch Poulsen company, which is still in business today. Its hybridizers created compact bushes with several clusters of little double blossoms by crossing small hybrid teas with dwarf China roses. In the 1950s, hybrid teas and floribundas were crossed to create the first grandiflora roses. The most common garden roses nowadays are these tall, resilient bushes with full-blossomed flowers, although they don't smell as good as Old World roses. Their popularity for a large-scale garden show stems from their more uniform form and vibrant, multicolored hues.
