What's nice about using a window box inside is that you can choose to go with a more decorative material, like the ceramic used for this minimalist-looking planter. If red isn't your thing, the planter also comes in four other colors. It comes with a removable tray and has two built-in holes for drainage.

These planters work well for both succulents and small houseplants and hold approximately three to seven small cacti or two small African violets. Some shoppers have even used them as wedding table centerpieces, and others report that the planter is sturdy enough to sit outside on a deck as long as the temperatures don't drop below freezing.

Best Splurge: H. Potter Copper and Wrought Iron Window Box, 30 Inches

It has a high price tag, but rather than corrode, this 30-inch hand-crafted window box will only get better with time since it's made from rust-resistant stainless steel and covered in a copper finish. The box fits in a weather-resistant wrought-iron frame, and there are drainage holes to help keep plants from getting too soaked. Mounting hardware is included, and there are brackets that make it easy to remove the box when you need to.

H. Potter is a family-run garden decor business based in Idaho, and the company is known for its excellent customer service. According to customers, these planters are well worth the extra money as the quality is unparalleled and they look gorgeous no matter what you put in them.

With its crown molding details and glossy black exterior, this 3-foot window box would look great on many kinds of buildings, including a brick townhouse or a classic 19th-century home. It's also sold in a crisp, beachy white and a more mellow off-white, which the company calls "clay." This planter is tough enough to stay out all year, as it's made from rugged polyethylene hard plastic that contains UV-inhibiting resin to help it resist fading, and can be easily cleaned with a rinse from the hose. The three steel brackets are also covered in a powder coat finish to help them withstand rain and snow. Like the Balconera, the Nantucket window box has a self-watering system and uses a 2.5-gallon reservoir that helps take some of the guesswork out of plant care. When used in a residential home, Mayne offers a 15-year warranty on their window boxes.

Best Wrought Iron: Gracie Oaks Noles Wrought Iron Window Box Planter

This elegant-looking wrought iron planter, which is covered in a powder coat finish that's designed to resist the elements, is reminiscent of the window boxes in Paris and the French Quarter of New Orleans. It has a sturdy frame, weighs 16 pounds, and is meant to hold three individual flower pots. A 12-inch pot in the middle can be flanked by a pair of 8-inch containers on either side. It measures 30 inches long and has multiple mounting holes for securing it, although it doesn't come with hardware, so you'll need to supply your own to attach it properly. Even without the included hardware, customers are quick to report that this window box was beautiful, sturdy, and well-made.

What to Look for in a Window Box 


Whether your window box will be placed indoors or outdoors determines which material is best and what features the window box should have. Indoors gives you more choices for the material whereas outdoors, you need to look for a material that is weather-resistant and resistant to UV radiation so it won’t fade quickly, especially when exposed to full sun. 


Good drainage is important for plant health. Some window boxes have drain holes, others don’t so you need to drill them yourself. 


Measure the size of your window to determine how much space you have available to fit a window box. Make sure there are no delimiting factors, such as a crank-out window opening that would interfere with the window box. Also check the product description to see how many pots and which sizes will fit in the window box. 


Regardless of its weight, an improperly installed window box is a major safety hazard. To securely install a window box, its mounting or hanging brackets must fit the window. Another set of measurements might be required before you make a purchasing decision.

Some window boxes come with the mounting hardware, others don’t, which requires a trip to the hardware store and some handyman skills.


A self-watering system is a convenient extra feature that relieves you from the need to check on your plants daily,


  • How do you hang window boxes?

    There are two options for hanging window boxes, either with L-shaped heavy-duty brackets or with siding hooks. The brackets are screwed or bolted onto the wall. Vinyl siding hooks do not require drilling, they are inserted into the seam between two siding panels. Make sure that the weight of your filled window box, including soil with plants after watering, does not exceed the maximum weight specified for each support system.

  • Should window boxes be wider than the window?

    A window box the width of the window up to a couple of inches more on each side, or to the point where the window trim ends, looks best.

  • How do you hang window boxes on brick?

    It requires drilling bore holes into the brick to insert plastic wall anchors. The mounting brackets are then fastened onto the wall anchors with lag screws.

  • What vegetables can you grow in window boxes?

    You can grow short vegetables with small root systems such as lettuce, microgreens, spinach, radishes, as well as a herbs in window boxes.

  • How deep do window flower boxes need to be?

    For aesthetic purposes, a window box with a depth of about 25 percent of the window's height is most flattering on the home. It's also important to consider the plants you intend to include in your window box; plants with more robust root systems will require a deeper box than one used for herbs. Eight to 12 inches is typically appropriate for most window-box plants.
