Window Boxes

Choosing the Right Size Planter Boxes for Your Windows

When choosing a window box planter size, be sure to measure first. Measure from left to right, notating any space constraints. You want to choose a plant box size that is at least as wide as your window, with no more than 4" of overhang on either side (you can choose a size up to 8" wider than your window). This will create a display that is appealing to the eye, adding attractive curb appeal.

From simple to ornate, traditional to contemporary, rustic to elegant, our boxes really run the gamut. From the clean, crisp lines of our Unity Chic tapered modern window box to the detailed swirls and blossoms of our French Quarter aluminum flower box planters, we offer a vast selection of containers suited to any stylistic taste.

Popular classic and traditional window box designs include:

  • Hayrack Troughs - Add country charm to windows and balcony railings with handmade wrought iron window planters, complete with moisture retaining coconut coir liners. Standard and XL versions available.
  • European Cage - For old world and European styling, look to our handcrafted wrought iron window box cages. These generously-sized rectangular planters can be used with 8" flower pots or one of our liners. Hand bent scrollwork adds intricate detailing. Liner choices include White, Black, multiple metallic, and 100% real copper.
  • Orleans Cage - Boasting Southern charm, this aluminum window box will have your balconies looking like the streets of the French Quarter in New Orleans in no time!
  • No Rot New Haven - Ideal for Cape Cod style homes, nothing says "Home Sweet Home" like the classical decorative trim on these PVC window boxes. Accent this box with faux brackets and self-watering reservoirs for a maintenance-free package with panache.

Popular contemporary/modern window box designs include:

  • Urban Farmhouse (Distressed Reclaimed Wood Finish) - Made from lightweight and durable fiberglass, the Urban Farmhouse window boxes mimic reclaimed wood planters without pesky drawbacks like refinishing, bug infestations and rotting. They're easy to install and built to last a lifetime! Also available in Reclaimed Dark Hickory, Cherry, and Distressed Driftwood finishes.
  • Unity Chic - Straightforward and unapologetically contemporary, these simple white window boxes are sleek and streamlined, providing a clean backdrop that allows your flowers to shine. Decorative corbels and self-watering planter box reservoirs are easy-care additions that make a big impact.
  • Arch Tapered - Slightly more petite than our wrought iron cages, and with tapered silhouette, the Arch iron window boxes match nearly any architectural house style. And with 9 liners to choose from, you're sure to find something that looks amazing on your wall or deck railing. These flower boxes are beautiful as well as an excellent value!
  • Bronze Lancaster - A mix of modern and traditional, the Lancaster features a classic burnished ArmoreCoat finish paired with clean, contemporary lines. While this looks like a metal planter box it is actually made from no-rot PVC composite. No rusting, no rotting -- timeless elegance!

Material Types and Benefits of Flower Boxes

  • Wrought Iron - All of our wrought iron window boxes are powder coated to resist chipping, fading and rusting. It's a baked on paint finish that lasts longer than conventional painting and protects the metal better. You have a lot of design play with these containers due to the expansive number of liners and flower pots you can add to personalize to taste. If you like European and old world styling or are creating a courtyard garden, wrought iron is a perfect choice.
  • Aluminum - Like wrought iron, aluminum metal window boxes feature a weatherproof powder coat finish and a plethora of liner options. Unlike iron, aluminum does not rust making it ideal for use in coastal areas.
  • Copper - Copper window boxes are the definition of luxury garden products. We use 100% raw copper for our products, so you can expect the metal to patina over time to a blue-grey hue. The copper is flawlessly hand-polished, creating a striking contrast when paired with black wrought iron. Copper naturally deters slugs and snails.
  • Fiberglass - Known for being extremely durable and lightweight. High level of detail and design customization available. Fiberglass can be made to look like wood, stacked stone and other maintenance-heavy materials. Fiberglass planters come in many colors and are crack resistant.
  • PVC Composite - Cellular PVC composite is a solid core material that looks and feels like wood. Unlike wood, it is impossible for PVC to rot, twist and warp. Composite PVC is inherently white but can be painted. Popular for coastal areas.
  • Vinyl - Pre-molded vinyl window boxes will not rot or discolor in the sun and are offered in a variety of fun colors. Vinyl is a lightweight material and many containers feature integrated sub-irrigation systems. Self-watering window planters are great for travelers and busy professionals.
  • Wood - There really is nothing like the classic beauty of real wood window boxes. Our wood window planters are made of naturally insect and rot resistant redwood and cedar. Sustainably sourced timber is used and all wood boxes can be ordered unfinished, making them perfect for use as chemical-free organic gardening planters.
