Add Structure and Style to a Large or Shapeless Space

Whether you’re terracing a landscape along a staircase or using edging to reimagine a large rooftop, edging and retaining wall planters unlock infinite design options:

Flexible Configuration: Ideal for shaping a walkway, staircase, or courtyard, these planters offer unmatched flexibility and creativity, allowing you to design truly spectacular spaces.
Bottomless Design Option: Using a wall-only setup that’s reinforced with gussets and internal stiffeners for added strength, this bottomless planter design gives plants uninhibited access to the soil below and facilitates irrigation.
Customized Solutions: Each section is manufactured to meet your specific needs and shipped ready to be assembled by you on-site. Learn more about Bottomless Retaining Edging Planters.
Anchoring Features: For some designs, anchoring the baseplate is recommended—and in certain cases, required—to ensure proper alignment and stability, providing a secure and lasting installation.

“I worked with Eric Gustafson on a project with an extremely tight deadline. He promised me delivery by the 7th. He delivered on the 6th. This hardly ever happens in our industry. My client could not have been more pleased. He was also a pleasure to work with. Product was exactly as expected. I will certainly work with Pure Modern again and strongly recommend them.”
