Studies were conducted at the Texas Agricultural Experiment Station, Dallas to determine nitrogen and phosphorus requirements of Salvia greggii Gray. (autumn sage), a resource-efficient landscape plant for the Southwest. Maximum growth of potted rooted cuttings used in the studies was obtained with application of 200 mg/liter (ppm) N and 50 mg/liter (ppnl) P, although fertilization with 150 mg/liter (ppm) N and 30 mg/liter (ppm) P would produce near maximum growth. Tissue levels should be > 2.2% N and > 0.20% P for these elements not to limit growth.
