Abstract. Evaluation of the decorative qualities of grades hosts the most important criteria in connection with the varietal characteristics studied host (Guacamole, Fragrant Bouquet, June), used in ornamental horticulture south of the Tyumen region. Revealed that our region is in a favorable climatic zone for hosts July temperature is 16–17 °C, therefore, cultivation of the host in the open ground is possible. We made phenological observations and biometric measurements according to the research plan accounting plot size of 25 m2, the total experience of the area — 300 m2. It is proved that the three studied host the best indicators of phenological observations, biometric accounting, for leaf area, leaf number and height of the bush varieties have been Guacamole Solberg. When planting in early May all host plants normally have taken root, and in mid-May has already begun an active leaf formation. The first phase is entered formation rosette plant varieties June — 16.05.12, second class — Fragrant Bouquet — 18.05.12. The final began to show signs of regrowth of fresh leaves of a plant variety Guacamole-Solberg (19.05). In budding stage main peduncle plants entered at different times with an interval of 26 June (variety Fragrant Bouquet) until 29 June (Guacamole-Solberg grade). The beginning of flowering was in order from grade Fragrant Bouquet July 1, grade June July 3 to grade Guacamole-Solberg July 4th. The first lost ornamental varieties flowers was Fragrant Bouquet (21.07), the latest in the variety was Guacamole-Solberg (26.07). It was the same variety the largest diameter rosette of leaves — 76 cm. It is 24 cm longer than that of the control variety Fragrant Bouquet. Grade June showed the average results compared with these varieties, the diameter of its outlet was 61 cm, which is higher than in the control cultivar Fragrant Bouquet for 9 cm and less than grade Guacamole Solberg for 15 cm. It is noted that a variety Guacamole Solberg was thus a decorative rosette, with its large yellow-green leaves with wide dark green border and aromatic lavender flowers (5.0), the second place a control Class fragrant Bouquet — 4.8 score and the third grade June — 4.6 points.
