Abstract
Many sage species can withstand extreme heat and drought climates making the plant suitable for versatile environments. Because of this, Russian sage leaves tend to decompose slower than other species. The hypothesis of this experiment was that decomposition in an area with higher sunlight would occur at a higher rate compared to the bags placed in the shade. During a twelve-week period, decomposition of Russian sage, Perovskia atriplicifolia, was studied on one of Belmont’s green roofs. The decomposition rate was determined by the use of sixteen leaf litter bags containing dried sage leaves. Eight were positioned in an area of sunlight and eight in a mostly shaded area on the green roof. Bags were collected throughout the study and weighed to determine percent mass loss. The hypothesis was supported as bags placed in sunlit areas weighed less, therefore decomposed faster. Results indicated that Russian Sage leaf decomposition occurs quicker in sunlit environments.
