Best Galvanized Steel Window Planter Box
With its sought-after cottage charm, this durable Jaimee-Lea Galvanized Steel Window Box is practical and decorative. It features a tapered silhouette with a burnished, distressed finish, and the galvanized steel is nearly impervious to damage from UV rays and rain.
Although it may look heavy, it weighs only three pounds, so you don’t have to worry about it collapsing under its own weight. It comes in Nantucket Blue or, in keeping with the cottage theme, Cape Cod White.

Best Copper Window Planter Box
Trends come and go, but copper has long been the standby metallic workhorse thanks to its durability and warmth. Cooperheadcraft’s Copper Window Planter is the latest example.
Constructed from 16-ounce copper, the planter measures 30- x 5-in. at its widest, tapering down to 28- x 4-in. It arrives bright and shiny. You can retain that look by spraying it with a clear protective coating, or let it turn a natural patina over time. Either way, this window planter box should last for years and years.

Best Hayrack-Style Window Planter Box
Inspired by the hayracks of England (self-service feed troughs for cows and horses), Vigoro Metal English Horse Trough Coco Planter provides 36 inches of rustic charm.
Framed with powder-coated metal in a rich black finish, it’s lined with coco, a natural, biodegradable fiber that helps retain moisture. At the end of the growing season, toss the used coco liner into the compost pile and order a replacement for next year’s “crop.”
Install the planter with the adjustable brackets (included), or hang it on screws or nail heads with the keyhole slots at the back.
