Representatives of the genus Pelargonium L'Нer belong to one of the most common flower crops. Today, thousands of highly ornamental pelargonium species (zonal, large-flowered, ivy-leaved, fragrant, unique, and angels) are used in landscaping cities around the world. Therefore, the need for accelerated reproduction of valuable plants most adapted to local conditions increases. The implementation of the planned landscaping programs at the present stage can be successfully implemented if they are based on the results of scientific research. The solution of these issues will open up wide opportunities for the use of pelargonium in landscape gardening of the Nikitsky Gardens and the Crimea as a whole.
