"Better than wood concept"
  • Never rots, plant directly in box - LIFETIME Guaranteed
  • Looks like wood, not shiny plastic
  • Can be painted to match rails or left unpainted (comes in white)
  • Custom lengths up to 16 feet
  • Can accommodate almost any rails - wood, vinyl, metal, composites
  • Solid material never warps or cracks during winter freezes
Our window boxes have been featured on The Today Show as "the last window boxes you will ever buy."


* The small square with an X in it is an offset strip to keep the box from tilting forward. We provide one for you which will accommodate most cases.

Balcony Rail Planters

Our balcony rail planters are a great fit for transforming a balcony into a garden paradise. The metal brackets simply bolt into the back of our boxes and allow the boxes to easily fit over railings from 1.5" wide up to 3.5" wide. Custom width railings can be accommodated upon request. For more information about how you can make over your balcony rails please give us a call today.
