Why Buy Low Profile Planter Boxes?

Our low profile planter boxes are durable and tough, made with easy-care finishes, and built to resist the elements and to stand the test of time. With weatherproof UV Protection & Frost-Resistance, they are just as comfortable outdoors as they are in and sit perfectly flanking any exterior door, walkway, or path. They also look great when placed around a balcony or porch.

Low profile planter boxes are ideal for when you want a sleek  organized look, but they are also incredibly versatile. They can either take on the role of modest backdrop — while bright attention-grabbing plants draw the eye — or they can come into their own when paired with succulents, herbs, and subtle neutral plants that accentuate the planter’s classic, timeless design.

Durable, lightweight, stylish, and versatile, low profile planter boxes are classy enough to decorate an interior space and sturdy enough to add character to an exterior space. — all while withstanding the outdoor elements. 

Our Range of Low Profile Planters

Our low profile planters come in a wide range of colors and styles, all capable of adding a unique touch. We have over 45 different colors with low gloss or high gloss finishes, provided with or without drainage holes depending on each planter's purpose and destination. 

All of our low profile planter boxes measure 12” tall and 14” wide but we offer three different lengths in 36”, 48”, and 65”. The 36” low profile planter box excels when lining a walkway or patio. It can define a home or business space, offering an organized look while bringing the outdoors in.

The 48” planter box is a more substantial piece that can occupy a large space in a home or yard but can also be used to add a touch of nature to a patio or deck. Our largest 65” low profile planter box comes into its own when more spacious outdoor areas need sprucing up. Large enough to separate two outdoor spaces, but modest enough to be placed behind a couch or in front of floor-length French windows on a balcony. 

Colors depicted on your screen may vary from how the planter looks in different lighting situations. To guarantee color match, please order a sample from our available color swatches.

Choose the Right Size and Layout

Low rectangular planters work best when they fit naturally into the flow of your space. Here’s how each size comes to life:

• 14" x 14" x 12" (cube) - Perfect as a small accent by steps, at entries, or to cap off the end of a longer row.
• 36" x 14" x 12" - A tidy span under windows or flanking a doorway.
• 48" x 14" x 12" -  The go-to choice for balcony rails, between posts, or along a bench back.
• 60"–72" x 14" x 12" - This long low planter is ideal for edging patios, pool decks, storefronts, or rooftops where long, low definition is needed.

? Tip:  For a streamlined look, line up two or three of the same length in a row. To stagger around corners or add rhythm, mix 36" and 48" sizes. And if you’re working along a walkway, leave 18–24 inches of clearance so foot traffic feels comfortable.

Planting Ideas That Work Best

At just 12 inches tall, these planters are best suited for shallow-rooted, compact plants. The effect is modern, graphic, and endlessly adaptable.

For full sun 

Choose plants that love the heat and reward you with color and structure. These picks thrive outdoors and keep their shape all season long.

• Low ornamental grasses like blue fescue or dwarf fountain grass
• Compact lavender, rosemary, and thyme for color and fragrance
• Trailing sedum, million bells, or portulaca for soft edges
• A clipped row of dwarf boxwood or dwarf yaupon for a clean, hedge-like look

For partial shade or bright indoor light

Not every space basks in full sun. These greenery options stay vibrant in filtered light or bright indoor conditions.

• Trailing pothos or philodendron mixes
• ZZ plant ‘Raven’ paired with silver satin pothos
• Low sansevieria, peperomia, or trailing ivy geraniums in bright windows

For a modern desert vibe

Prefer something sculptural? Succulents and cacti bring a contemporary vibe, perfect for dry, sunny spots or minimalist interiors.

• Mixed echeveria and aeonium rosettes with string-of-pearls spilling over the edge
• Evenly spaced golden barrel pups for a bold, graphic row

For soft, textural borders

Sometimes you just want a gentle, flowing edge. These plants add movement and texture, softening the crisp lines of the rectangular planter.

• Liriope or mondo grass planted as a ribbon
• Trailing dichondra ‘Silver Falls’ cascading over the front lip

? Tip: Space plants about 8–12 inches apart for a continuous look. Use a lightweight, well-draining potting mix, and add drainage holes outdoors. For indoor use, line the planter and place felt pads beneath to protect floors.

Pick the Right Color and Finish 

Color and finish set the mood. Whether you want your narrow planter box to disappear into the background or pop as a statement piece, these pairings make it simple:

• Matte black - Crisp contrast against white siding or light stone. Pairs well with black-framed windows and concrete pavers.
• Matte or gloss white - Brightens shaded patios and looks striking against brick or dark decking - a go-to for coastal spaces.
• Charcoal or gray - Blends with concrete for a smooth architectural look, letting greenery take center stage.
• Warm neutrals (bronze, tan) - Perfect with teak or ipe decking, stucco, and warm-toned architecture.
• Bold hues (navy, red, yellow) - Great for branding or wayfinding in cafés, hotels, or retail spaces. Pair with simple green or white plants to keep it balanced.

? Tip: Not sure which shade will look best? Order free color swatches before you decide and see how each finish looks in your space.

Steal Our Placement and Styling Tricks

The beauty of a long narrow planter box is how easily it fits into architectural lines without blocking views. Check out these top styling shortcuts:

• Match planter length to windows or railings - Pick a size that mirrors the bay width for a built-in look.
• Create a green backrest - Place a narrow planter behind a bench for life and softness without blocking views.
• Frame patios with symmetry - Use two 72" planters and a 48" in the center to outline dining or lounge areas.
• Define balcony edges with flow - Line the sides with long planters but keep corners open for easy movement.

How to Care For Your Planter 

Keeping your low profile planter looking its best is effortless, whether it’s inside or out. Just follow these simple steps:

• Outdoors - Always choose drainage so water flows freely. Elevate your narrow outdoor planter box slightly, and add some weight if it’s in a windy spot.
• Indoors - Skip drainage holes and line your narrow indoor planter box with a waterproof tray. Felt pads underneath protect your floors from moisture.
• Seasonal care - Top off soil, refresh plants, prune when needed, and add a slow-release fertilizer in spring to keep everything healthy.
• Finish care - A quick wipe with a damp cloth is all it takes to maintain its polished, like-new appearance.
