The experiment was carried out to study the influence of planting densities and on some agronomic characters and yield of rresh weight in Agastache rugoso. The results obtained are summarized as fol-lows; stem length was long in dense planing and short in spacious Planting. Stem diameter was thickIn spacious planting, and was thin in dense planting. Yield was higher in dense planting densities (20x20cm : 2spiants/m, 30x20cm : 17plants/m).
