The study evaluated the morphological characteristics of the collection of Paniculate phlox domestic cultivars (Phlox paniculata L.) of N.V. Tsitsin’s Botanical Garden of the Russian Academy of Sciences. Cultivars were rated by valuable decorative features in order to select a new breeding material suitable for use in cut flower production and gardening. Accounting of economic and decorative features were carried out within two years, in accordance with the methodology of state cultivar testing. The data obtained are statistically reliable. The complex of morphological features revealed promising domestic cultivars – ‘Gegery’, ‘Timur’, ‘Rozovy kovyor’, ‘Michurinets’, ‘Sigismund Levanevsky’, ‘Atlas’ and ‘Nebesa’, which are valuable breeding source material for domestic cut flower production.
