A watering nozzle including an outer casing having a water discharge screen and an inner casing having a supply passage is provided. The water discharge screen includes an inner region and an outer circumferential region. The outer casing includes a first passage communicating with the inner region and a second passage communicating with the outer circumferential region. Relative rotation between the outer casing and the inner casing enables the outer casing to make a relative displacement in the longitudinal direction with respect to the inner casing. The relative displacement enables selection between the first passage and the second passage. A shower hole is provided in the inner region. The discharge flow rate of water from the inner region can change based on the relative displacement.
