Technical Abstract: The Agricultural Research Service, United States Department of Agriculture, hereby releases to nurserymen a new evergreen compact ornamental Hibiscus rosa-sinensis cultivar ‘U.S.S. ARIZONA’, which is recommended for trial by nurserymen and professional horticulturists as a summer flowering container plant nationwide or as a flowering landscape shrub in cold hardiness zone 10. Plants of ‘ U.S.S. Arizona’ are semi-compact, upright spreading with prolific flowering from spring to fall in temperate regions. Old flowers abscise freely with no production of seed pods, even when pollinated. Ultimate plant size is dependent on container size and environmental conditions with plants in a #3 nursery pot growing to 1.0 meters high x 0.5 meters wide within 6 months under optimum conditions. Under tropical landscape conditions plants should mature to approximately 3 meters high x 1.5 meters wide. The phenotype may be affected slightly by changes in cultural practices and environmental conditions such as light intensity, temperature, and nutrient level. ‘U.S.S. ARIZONA’ was selected for its exceptional vibrant orange flowers and outstanding appearance in containers, particularly for production in the South and marketing nationwide as a summer flowering accent plant for patios, pools or other outside areas.
