Perth is a modern tall rectangular planter with crisp, unfussy lines. At just 16 in deep, it slides into tight zones while the consistent 42 in height brings presence.
Pick a length from 24 to 72 in to go from a single moment to a long, tailored run that reads like a green wall.
First look
If you are after a modern planter that feels architectural without shouting, this checks the box. The silhouette is tall and narrow, so it lines up beautifully along walls, railings, and window bays. All lengths share the same height, which makes mixing sizes feel intentional.
Lightweight fiberglass keeps it manageable to install while the painted-to-order finish reads polished in both residential and commercial settings.
Where it works best
Use a single piece as a tall indoor planter beside a console, in a corner that needs height, or to soften a TV wall. At the entry, a symmetrical pair frames doors without blocking sightlines.
On terraces and pool decks, longer lengths create subtle privacy - think a living backdrop behind a sectional, along a balcony rail, or to guide foot traffic between zones.
For storefronts, restaurants, and lobby edges, a run of 60 or 72 in planters reads like a clipped hedge that directs the eye and cleans up the edges.
Scale and sizing guidance
Choose the length that matches the span you want to organize. Shorter options - 24 or 36 in - punctuate small porches and between windows. The mid length at 48 in settles nicely under picture windows or between patio doors.
The 60 and 72 in lengths become your planter of choice when you want a space divider or perimeter screen. Plan for columnar specimens, grouped 10 to 12 in nursery pots, or a repeating trio for longer runs. This proportion keeps the planting crisp and avoids the overstuffed look that can happen with wide box planters.
Design tips that make it sing
Echo the clean lines. The Perth pairs naturally with modern furniture, linear railings, large-format pavers, and concrete or stone plinths. If your home skews traditional, bridge styles by combining the sleek form with textured greens and warmer finishes nearby.
Repetition is your friend - repeating the height across multiple lengths creates rhythm along a facade. At entries, align the planter height with the handle or sidelight for a composition that feels deliberate. Indoors, tuck it 2 to 3 in off the wall to avoid scuffs and to give trailing plants room to drape.
Plant pairings that thrive
For full sun, build a breezy, low water mix with rosemary, lavender, blue fescue, and lomandra. The vertical lines stay tidy in heat and wind, while the fine textures read modern against stone and decking. A controlled cascade of Dichondra Silver Falls keeps it fresh without bulk.
For bright shade, lean lush and layered. Cast iron plant, evergreen ferns, heuchera, and carex give texture that reads well at eye level. Dwarf azaleas or camellias add seasonal color without outgrowing the footprint.
Indoors, pick statement greens that look sculptural from across the room - Ficus alii, rubber tree, Dracaena ‘Lisa’, Sansevieria Laurentii or Zeylanica, ZZ plant, or a compact Rhapis palm. If you are aiming for a tall rectangular planter box that stays tidy on a porch, mix one distinct vertical - like a columnar holly - with a low underplanting of heuchera or liriope so the profile stays clean.
Color combinations that elevate the space
Matte black turns the Perth into a tall planter that grounds light facades, pale decking, and breezy textiles. Pair with brass, aged bronze, or blackened steel for a cohesive modern read.
Bright white flips the contrast - a white planter glows against charcoal siding, black steel, or dark stone, and it makes foliage pop indoors next to cream walls and natural oak.
Go charcoal or gunmetal when you want contrast against light stucco or stainless details; cool-toned grasses and silver echeveria stay refined.
Choose bronze, dark brown, or matte terracotta when you want a warmer read with brick and limestone - think compact olives, rosemary standards, and lavender for softness.
If you want a single accent, lean into saturated colors like deep green, saffron, or eggplant, then keep neighboring pots and textiles calm so the planter reads as the intentional color moment.
Drainage, liners, and planting setup
Outdoors, request drainage holes and use a high-quality potting mix rather than garden soil. To control weight in the longest sizes, build a false bottom with lightweight inert fill under a geotextile layer, then soil above.
Indoors, either keep the planter sealed and use watertight liners or drop in nursery pots inside a single custom liner. Felt pads or risers under the base protect floors and allow airflow. If you expect seasonal swaps, the pot-in-pot method makes refreshes painless.
Style match and use cases
Modern and minimalist spaces are the obvious fit, but this tall planter for outdoor patio setups also plays nicely with rustic or coastal schemes when you pair it with warm woods and textured greens.
On porches, it does the work of a large box planter without eating up square footage. In commercial settings, repeat lengths to create extra large rectangular planters that act as gentle barriers around dining areas or to hide utilities with a clean edge.
The takeaway
Perth is a modern tall rectangular planter box that scales gracefully - from a single box on a porch to a continuous row of large planters along a terrace.
The slim footprint, consistent height, and broad color palette make it easy to specify. If you need a planter that can move outdoors when the season turns, or a planter that looks tailored year round, this is the smart, versatile choice.
