The article contains the results of the study of the antecological features, seed and vegetative propagation of valuable ornamental plant Phlox ‘Bill Baker’. Phlox ‘Bill Baker’ is resistant to adverse environmental factors in culture of a southern taiga of Western Siberia. Plants belong to group of long-term vegetation and summer flowering period cultures.The pollen grains have a high fertility and better germinate on agar with reduced sucrose content. Seeds and pollen grains size are stable, have a low variation (coefficient of variation is about 6 %), that allows use these figures as additional diagnostic features. The plants have a low real seed productivity and propagate principally by dividing rhizomes with kidney renewal.Phlox ‘Bill Baker’ is recommended for use in mixborders, the compositions of the landscape style, rocky gardens, landscaping slopes.
