Choosing the Right Size Planter Boxes for Your Windows

When choosing a size, be sure to measure your designated space first. Measure from left to right, noting any space constraints. You want to choose a planter 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.

Material Types and Benefits of Flower Boxes

  • Wrought Iron - All of our wrought iron styles 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 features 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 material will not rot or discolor in the sun and are offered in a variety of fun colors. Vinyl options are lightweight and many feature integrated sub-irrigation systems - great for travelers and busy professionals.
  • Wood - There really is nothing like the classic beauty of real wood. Our wood products are made of naturally insect and rot-resistant redwood and cedar. Sustainably sourced timber is used and all units can be ordered unfinished, making them perfect for use as chemical-free organic gardening planters.
