In the botanical institutions of the country, it is important to create, maintain and develop various thematic collections of plants of temperate, subtropical and tropical regions of the Earth. Focusing on the creation of collections of species of local flora, special expositions of the ethnobotanical knowledge of the indigenous population of the region, and collecting not only living plants, but also creating carpological collections (fruits and seeds – reproductive diasporas), including introducing and replenishing the genetic bank of long-term seed storage of species of local flora, including necessarily rare and economically important. Collected, stored, maintained and restored collections and expositions of living plants should be used as a base not only for research purposes, but also for educational programs and to perform teaching functions designed for schoolchildren, university students and nature lovers. It is imperative in each botanical garden to make collections of rare and protected species, valuable useful species of natural flora, and, if possible, not forgetting about traditional vegetable and fruit plants that are also important to exhibit in the gardens. It is important to keep track of collection material, maintain detailed documentation for each collection. By analyzing the collected perennial data, it is possible to develop a modern promising range for urban gardening, urban floristics, and cultivate agrotechnology of cultivation for the introduction of plants into culture. However, in all the work on introducing new species into the culture, it is now always necessary to pay attention and evaluate the reproductive strategies of the species – in order not to “release the gin from the jug”, evaluate the invasive potential of the species introduced into the collections, so as not to increase their number in the region’s and the country's flora.
