    Best Uses

      We have an elevated deck off of our living room with 8' sliders. These "window" boxes will bring the beauty of our flower gardens right to us, along with the added benefit of butterfly and hummingbird attractors...a lovely enhancement to our mountain view! Also convenient to the kitchen for picking fresh herbs! As we are renting the house, we can add all the planters we want without having to attach them with hardware, and if we do ever decide to move they are "good-to-go" even in the growing season. And we don't have to worry about watering if we are away for a few days here and there this summer. Such a deal!
