how long for pineapple to mature
Very slow-growing plants, pineapples can take between 1 1/2 to 2 1/2 years to fully mature. Once a pineapple matures, only then will it blossom and set fruit. Pineapples are warm-weather plants, hardy in U.S. Department of Agriculture plant hardiness zones 10 through 11; they are intolerant of cool weather.
