Abstract: Korarima (Aframomum corrorima (Braun) P.C.M. Jansen), a slow growing and persistent under tree shade as an under-story perennial plant, is native to Ethiopia. When it is grown in full sunny condition, all plants die off a few weeks after planting, but the effect of different shading materials on its growth is not known. Half a year old korarima plants were planted under differently coloured plastic shades (red, green, blue and clear) and coffee (Coffea arabica L.) tree shade to regulate the growth. The coffee tree shade was used as control. Varying levels of photosynthetic photon flux density (PPFD) and red to far red (R/FR) ratio of light were recorded under different shaded and open conditions. The korarima plant responded differently to the different plastic and coffee tree shades. Average plant height, number of leaves per plant, number of sprouts per plant, chlorophyll content, leaf area, total fresh and dry weights were significantly different when recorded at different stages of growth, highest being recorded under the blue plastic cover. The minimum efficiency was achieved under control..
