Rectangular Planters

Long Rectangular Planter Boxes At Flower Window Boxes TM we specialize in rectangular planters made from an architectural grade PVC. All of our PVC planters are handcrafted by carpenters from a revolutionary material that doesn't rot, crack, sag, or split. They ship fully assembled as well and come with an optional watering feature that turns them into self-watering planters. Our long rectangular planters boxes come in over 100 sizes and oblong and trough shapes and over half a dozen different styles to choose from. They can be used in a variety of outdoor applications including decks, porches, patios, gardens, rooftops, businesses, restaurants, and more! We can customize them with wheels to roll and also custom make them to virtually any size for any project no matter how big or small.
