Our square steel planters bring clean, architectural structure to gardens, patios, entryways, rooftops and commercial landscapes. Each planter is made from durable 2 mm steel in your choice of Corten weathering steel or powder-coated black steel, and is available in seven standard sizes, from a compact 16 in cube to a large 39.5 in cube and two low-profile styles. Every planter is made to order, and fully custom sizes, shapes and colors are available.
Modern cube planters for entrances, patios and projects
A square planter is the simplest way to add height, rhythm and greenery to a modern space. Use a pair to frame a front door, line them up along a terrace, or use one large cube as a standalone feature. The low-profile sizes suit seating areas, walkways and rooftops where a lower, wider silhouette works better. They hold shrubs, boxwoods, hydrangeas, lavender, ornamental grasses, herbs and small trees.

Finish options
Corten steel
Corten is a weathering steel that develops a warm, rust-toned patina outdoors. The color deepens over time as a stable protective layer forms, so no painting or sealing is needed. During the early weathering period, rust-colored runoff can mark light-colored porous surfaces such as pale concrete or stone, so we recommend placing Corten planters on gravel, pavers or a surface you are comfortable with.
Black powder-coated steel
A durable black powder coat that stays bold and low-maintenance, for a crisp modern look next to greenery, stone and timber.

Frequently asked questions
What are the planters made from?
They are made from durable 2 mm steel, finished in Corten weathering steel or black powder coat.
Will Corten planters stain my patio?
While the patina is forming, rust-colored runoff can mark light-colored, porous surfaces. Placing the planters on gravel, pavers or another surface you are comfortable with avoids the issue. Once the patina stabilizes, it becomes the protective surface of the steel.
Do the planters need assembly?
Yes. Assembly is required.
Can I order a custom size, shape or color?
Yes. All planters can be customized, including sizes, shapes and finishes. Email nuvardesigns@gmail.com for a quote.
Do you take bulk or commercial orders?
Yes. Bulk and commercial orders are welcome. Email us with your quantities and sizes for a quote.
