A combination plant box and fire escape ladder includes an anchor rail for fixed attachment to an outside wall of a building, a frame for holding a top rung of the ladder outwardly from the wall, a pair of flexible cables forming the ladder rails, and a plurality of lower rungs. The plant box is attached to the flexible rail ends remote from the top rung, and the lower rungs are attached to the flexible rails between the top rung and plant box. The frame includes a center portion lying adjacent the wall and two end portions which project generally perpendicularly from the center portion and the wall to support the top rung. The anchor rail is provided with a pair of attachment points by which the frame is attached to the anchor rail. The upper ends of the flexible rails are attached to respective attachment points of the anchor rail and extend through the top rung to fix the lower rungs in spaced apart relation from the wall. Each lower rung is in the form of a hollow tube with opposed passageways at each of its ends. Each flexible rail extends through one pair of the passageways at a respective end of the tube. Cable clamps fix the positions of the rungs with respect to each of the flexible rails. The flexible rails pass freely slidably through the passageways in each end of the tube, such that the lengths of flexible rail between each pair of adjacent rungs can be stored within the hollow tube forming one of the adjacent rungs when the fire escape ladder is in a stored position. The ladder further includes a tray for use when the ladder is in a storage position, the tray including a downwardly opening channel adjacent the front edge thereof, a botton and a back. The top rung is received in the downwardly opening channel with the bottom supporting the stored rungs and rails, and the back lying adjacent the frame back member to hold the tray in position.
