Abstract
Due to the lack of information about biomorphological features and cultivation technology of species of the genus Nemesia Vent they are still rarely found on the territory of Ukraine and thus are of great interest for cultivation and use for the design of flower beds. The purpose of the scientific work was to analyse the current world assortment of the genus Nemesia Vent, as well as to study the features of flowering, reproductive ability, agrotechnics of growing cultivars of nemesia strumosa, and assess the prospects of their use in decorative gardening in Ukraine. During the research of nemesia strumosa cultivars, laboratory and field research methods were used. It was proved that all the studied cultivars received high ratings of their decorativeness, since the plants under the experimental conditions had well-developed inflorescences, abundant and long-lasting flowering. The plants retained the brightness of their colour throughout the entire period of the flower's life, adapted well to growing conditions, were practically not affected by diseases, and in general were quite resistant to unfavourable conditions. The Orange Prince cultivar proved to be the best of all the cultivars studied in terms of the duration and intensity of flowering, which reached its maximum values on the 60th day from the beginning of the phase with the number of 35 flowers per plant. The studied cultivars can be used in greening health complexes, recreation areas, office territories, adjacent territories, as well as in the design of various types of flower beds. The results of the obtained research are primarily necessary when choosing use cases, developing agricultural technology and breeding programmes, and for carrying out research work aimed at meeting the needs of horticulture. Considering that they are grown both for the needs of the protected ground and open gardening, the study of these issues is a significant contribution for botanical science in general, primarily for decorative gardening in Ukraine, as well as for practical floriculture and landscape design
Highlights
The current stage of ornamental plant industry development and the solution of practical problems relevant for Ukrainian horticulture requires the increasing attraction of new types and cultivars of flower-decorative cultures for mass and individual gardening, as well as for the design of collection funds

Summary
The current stage of ornamental plant industry development and the solution of practical problems relevant for Ukrainian horticulture requires the increasing attraction of new types and cultivars of flower-decorative cultures for mass and individual gardening, as well as for the design of collection funds. The creation of large industrial centres and the growth of the urban population cause environmental degradation In this regard, the need for mass recreation of the population in conditions that favourably affect health and psychophysical state increases [1; 2]. Among a wide range of flower-decorative cultures, plants of the genus Nemesia Vent family Scrophylariaceae Juss are among the most promising for introduction to Ukraine [3; 4]. They occupy one of the leading places in the world assortment of ornamental plants of the world flora. Flower-decorative plants of the genus Nemesia Vent at this stage of floriculture development are rare and are found only in private collections and as a seed material in a commercial offer, but based on the decorative qualities of these species and the variety of options for their use, these plants can be used to replenish the variety of flower-decorative cultures in Ukraine [3]
