These hanging baskets are great for gardeners on the go, or for those who forget to water their high water demanding plants or flowers. Your plants or flowers will pull water from the water reservoir when they need. This process also reduces the risk of over or under watering. The reservoir is hidden in the bottom of the pot, and can be filled via a hole in the side of the pot. The hanging basket is 12 inches in diameter x 5.5 inches deep
