Why Designers Choose the Julian Rectangle

The Julian Rectangle is the premier choice for professionals looking to maximize impact in narrow spaces. While a cube anchors a corner, this rectangular trough defines a line. If you have ever seen a standard plastic or resin trough "bow" or "belly" outward after being filled with soil, you will recognize the necessity of the Julian’s industrial-grade construction. It is designed to be a permanent, design-forward extension of your architecture.

In professional settings, these are most often used as "living walls" to create privacy between restaurant tables or to frame the perimeter of a rooftop deck. Because the 12" width is so slim and the Matte Black finish so sophisticated, the Julian Rectangle creates a clear boundary without sacrificing floor space. It anchors the environment, allowing your greenery to create a lush, vertical curtain.


The Science: Why Steel-Reinforcement Matters for Rectangle Planters

Longer planters are particularly susceptible to "bellying"—a phenomenon where the weight of heavy, wet soil forces the long side-walls to bulge outward. This ruins the crisp, architectural silhouette. To prevent this, NMN Designs integrates internal steel reinforcement into the Julian Rectangle.

This engineering ensures that even when housing a dense row of plants, the walls remain perfectly plumb and vertical. Combined with our commercial-grade fiberglass, you get a vessel that handles extreme thermal expansion (from scorching summers to sub-zero winters) without the cracking or brittleness found in standard retail pots.


Recommended Plant Pairings for the 30" Julian:

The 12" depth of the Julian requires a thoughtful selection of root-compatible plants. We recommend the following for health, aesthetics, and performance:

For Privacy and Height (Narrow Profile Specialists):

  • Sky Pencil Holly: The gold standard for 12" troughs. Its naturally columnar shape stays narrow and vertical without needing heavy pruning, providing a "living wall" effect.

  • Blue Arrow Juniper: A stunning, silvery-blue evergreen that is much more drought-tolerant and narrow-root-compatible than traditional Arborvitae.

For High-Contrast Color:

  • Red Star Cordyline: Features deep burgundy, sword-like leaves that look striking against the Matte Black finish.

  • Golden Creeping Jenny (as a "Spiller"): Plant these at the edges to create a vibrant, lime-green "waterfall" of foliage that pops against the dark fiberglass.

For Extreme Temperatures (Heat, Wind, and Frost):

  • Karl Foerster Feather Reed Grass: Virtually "bulletproof." It handles sub-zero winters and scorching summers with ease. Its tall, wheat-like stalks provide privacy and movement in the wind.

  • Green Mountain Boxwood: Extremely cold-hardy and classic. It can be easily maintained to fit the 12" width and provides a structured, formal look year-round.


Pro-Tips for the Best Results

  • High-Wind Stability: For exposed roof decks or coastal balconies, add 3 inches of heavy gravel at the base before adding soil. This lowers the center of gravity, ensuring your privacy screen stays upright during heavy gusts.

  • Thermal Protection: While the fiberglass is frost-proof, using an insulated liner inside the planter in extreme northern climates can help protect the root balls of perennial plants, ensuring they return season after season.

Boredom Buster!
Color: Drool Ranch Chips
I have a 46lb GSP and she loves little toys. These are perfect for her and she really loves the crinkle noise of the bag. These are big enough where I don’t have to worry about her choking on them. We have purchased multiple toys from Bark Box and they have all been quality toys and have survived a very active GSP gal.

My dogs are obsessed with these donuts
Color: Donuts
I got this for my 2 year old terrier for Valentine’s Day and it ended up being a huge hit in our house. She’s small and loves running around chasing squeaky toys, and the donut toys are the perfect size for her to carry, toss, and sprint after. For some reason the donuts are absolutely irresistible to the dogs. Not only does my terrier love them, but my 9 and 10 year old dogs, who are normally couch potatoes and usually ignore the mountain of toys we have, became obsessed with them too. They were stealing the donuts from each other and running around like puppies again. The little box makes it fun to hide the donuts back inside so the dogs can pull them out, which adds another layer of play. It’s adorable, well made, and shockingly none of them have destroyed the donuts yet, which is usually what happens to most toys in our house. It is one of the few toys that has actually kept all of my dogs interested. Definitely one of the best toys we have bought.

Smaller than expected
Color: Donuts
Wayyyy tinier than I expected but its ok, I have a mini dachshund and the size fits. She doesnt play with these as much as heretics other big girl toys but these are super cute. Each one has a squeaker which she loves to try and tear out. They are soft and squishy for her small teeth.

Love them! Dog is Obsessed.
Color: Donuts
These are absolutely adorable. Just the right size for my 20 ish lb pup. They seem to be durable and made from good quality materials. They're soft and light so they don't make any noise or issues when he chucks them across the room while he's playing. Definitely great value for great price.
