The Designer's Perspective: Why Ribbed Texture Matters

The Winona is a strategic tool for creating visual rhythm. While smooth-walled planters lean toward a silent minimalism, the Winona’s ribbed texture introduces "architectural shadowing." Designers utilize this texture to break up the visual monotony of long corridors or large glass walls, providing a tactile contrast that softens industrial materials like concrete and steel.

At 17 inches tall, this is a tall and wide trough with a commanding presence that effectively defines boundaries. The horizontal ribs draw the eye along the length of the long span planter, making narrow spaces feel more expansive and grounded. Additionally, the Matte Slate finish is a hospitality favorite because the texture naturally disguises fingerprints and water spots better than smooth-surfaced alternatives.

The Science of Structural Geometry

While traditional long planters often require internal steel reinforcement to prevent "bellying" (the outward bulging of the walls), the Winona utilizes corrugated structural engineering. Much like the ridges in architectural steel siding or a shipping container, the "peaks and valleys" of the ribbed walls significantly increase the material’s structural rigidity.

This geometry allows the fiberglass to resist the outward pressure of heavy, wet soil and root expansion naturally. By eliminating internal steel, the Winona remains more maneuverable than reinforced models while maintaining a crisp, architectural silhouette that stays perfectly plumb over time.


Versatile Settings for the Winona Span Block

  • Residential Balconies: The skinny (narrow depth) footprint fits perfectly against railings, providing a lush green curtain without blocking walkways.

  • Restaurant & Cafe Dividers: Create a "living wall" to separate seating areas from traffic with a durable, textured barrier.

  • Office Foyer & Building Entries: Use this long block to frame doorways or guide guests through large, open environments.

  • Rooftop Decks: Lightweight for weight-sensitive structures but engineered for high-wind stability when properly ballasted.

  • Poolside Perimeters: The Slate Gray finish and ribbed texture hide water spots and maintain a premium, spa-like feel.


Verified Plant Pairings (Optimized for 12" Width / Depth x 17" Height)

The 17" vertical depth supports healthy root systems, while the skinny 12" width is best suited for plants with an upright or cascading growth habit.

For Privacy and Structural Lines:

  • Snake Plants: A designer staple; the vertical, sword-like leaves provide a sharp, clean contrast to the planter's horizontal ribs.

  • Horsetail Reed: This architectural plant grows straight up and thrives in the deep, contained soil of the Winona.

  • Sky Pencil Holly: A columnar shrub that stays narrow. The 17" vertical depth is perfect for its root system, allowing for vertical privacy.

For Color and Cascading "Spiller" Effects:

  • Silver Falls: A cascading plant with shallow roots that creates a shimmering silver "waterfall" over the dark gray finish.

  • Sweet Potato Vine: Offers vibrant lime-green or dark purple foliage that drapes elegantly over the ribbed edges.

  • Geraniums: Classic flowering plants that thrive in the 17" soil capacity and provide consistent seasonal color.


Pro-Tips for 2026: Stability Meets Drainage

  • High-Wind Stability (The Hybrid Method): For exposed rooftop or coastal placements, add 2–3 inches of heavy river rock to the base. Important: Place a layer of landscape fabric over the rocks before adding soil. This adds necessary weight to prevent tipping in high winds without creating a "perched water table" that causes root rot.

  • Maximize Drainage: Modern horticultural science recommends avoiding the old practice of a loose "gravel layer" without a barrier. For best results, use high-quality potting soil throughout the planter to ensure consistent moisture wicking.

  • Planter Risers: For optimal drainage, use slim planter feet to lift the trough 1/2 inch off the ground. This breaks the surface tension between the planter and the floor, allowing gravity to effectively pull excess water away from the root system.

Helps with separation anxiety, keeps dogs busy
Size: Medium (Pack of 1), Product Packaging: Standard Packaging
Have been using kongs for my labs for years. Brand new the kongs do have a strong rubber smell. Try putting the Kong in a pot with water over low fire to help reduce the smell. Stuff with favorite treats or fill with peanut butter and freeze. Will keep dogs busy and chewers with an indestructible toy

Very durable and my Dutchie loves it
Size: X-Large (Pack of 1), Product Packaging: Standard Packaging
This is one of many Kongs I have purchased through the years. This one was the extra large that was purchased for my Dutch Shepherd. Every night at bedtime, he gets his Kong stuffed with some dry food, treats, and a nubs bone to hold everything in place. He loves his Kong and runs for his crate at bedtime. Usually, he doesn’t eat the treats immediately. But sometime during the middle of the night, he will wake up and eat. Every Kong I have purchased through the years has been very durable. I highly recommend this product for all sizes of dogs.

Best chew toy and training item on the market!
Size: Small (Pack of 1), Product Packaging: Standard Packaging
I'm a Dog Trainer, specializing in early canine education with Puppies between eight and 18 weeks . The Kong is the best thing you can give a dog! You can stuff these things with all kinds of yummy things. I love to get creative with the Kongs. Adding novelty to your dog's life improves their brain health. I can't even give examples because I would be here all day. For dogs who eat kibble you can soak your kibble in water or better yet bone broth, then once it's soft, fill the kong with the kibble and put it in your freezer. Keeps your dog busy for a long time, you don't have to buy extra stuff because you just give them the kibble you're already going to give them. (I recommend getting at least one, but up to six for each dog so you can give them their entire daily allowance of food in the Kongs). The licking /chewing helps them relieve stress and gives them something to enjoy inside their crate. I learned this from Dr. Ian Dunbar and I highly recommend his training courses on a platform called Dunbar Academy to learn how to properly raise a Puppy into the best dog you've ever had. He has helpful information for older dogs too, but you really want to train your puppy properly so you can avoid the behavior problems in the first place. It's super cheap too, and easy to learn from. Plus these are great chew toys for heavy chewers because as long as you get the right size for your dog, they can't destroy this thing! AND it bounces, so you can actually play fetch with it like it's a ball. Every single dog deserves a Kong, so if you don't already have one, go ahead and do that right now. You won't regret it, and your dog definitely will love you more.

My pup loves her Kong
Size: Small (Pack of 1), Product Packaging: Standard Packaging, Size: Small (Pack of 1), Product Packaging: Standard Packaging
My little pup loves her Kong! She’s about 14 pounds so I recommend any dog with that size to get the small size. The quality is great. Extremely durable, but still workable enough for her to get in and find all the goodness!
