Features of growth and development of hesperaloe small-flowered Hesperaloe parviflora (Torr.) J.M. Coult. on the south coast of Crimea

The results of the primary introduction test of small-flowered hesperaloe (Hesperaloe parviflora (Torr.) J.M. Coult., 1894) in the Nikitsky Botanical Gardens (NBG), on the Southern Coast of the Crimea (SCC); in Sevastopol (Cape Fiolent) are presented. The features of the growth and development of the studied plants growing in open and protected ground are given. Factors affecting the set of fruits with viable seeds have been identified, the frost resistance of this species has been determined. Based on long-term observations, it has been established that Hesperaloe parviflora is very resistant to fungal diseases, viruses and harmful insects, which have not been detected over many years of research. We have been developed criteria that in the future will allow us to provide scientifically sound recommendations on the agrotechnics of growing small-flowered Hesperaloe in the conditions of the Southern Coast of the Crimea (SCC) and on the Black Sea coast of the Caucasus (BSCC). As a result of the studies of small-flowered Hesperaloe, it has been proved that this species has successfully passed the primary introduction test and is promising for gardening on the SCC.
