This study was conducted at the nursery of the Department of Horticulture, Faculty of Agriculture, University of Khartoum. The objective of this study was to determine the effect of height of pruning on coppice (number of new shoots/plant, plant height and number of leaves/plant) and flowering (duration from pruning to flowering, flower yield by number and weight, number of flower clusters and flower stem length) of rose cultivar "Sara". Plants of the rose cultivar "Sara" were pruned to 60cm (high pruning), 40cm (moderate pruning) and 20cm (Severe pruning) above the soil level. Severe pruning depressed coppice and yield, delayed the onset of flowering. Moderate and high pruning gave more vigorous plants, higher flower yield and earlier flowering. Moderate and severe pruning gave longer flower stems.
