Custom Painted Planter Boxes
The Jakarta Light Grey Fibreglass Planter Boxes shares their DNA with our popular Manhattan line, but with a distinct difference. We’ve stripped away the top coat, leaving a sophisticated light grey undercoat, and passing the savings on to you.
This durable finish is weather-ready and naturally UV-resistant, so it will stand up to the elements beautifully. Ideal for those who crave a personalised touch, the Jakarta’s light grey canvas is ready for your custom paint job. Or, embrace its understated elegance as is — the subtle hue provides a refined backdrop for your planter boxes that lets your plants take centre stage.
Warranty?
Built for Every Boundary and Border
Planter boxes carry more than soil — as borders, screens, and boundary markers, they take daily knocks from foot traffic, trolleys, and equipment that a standalone pot rarely faces. When you invest in large planter boxes to define a walkway or courtyard, replacing a damaged unit isn’t a simple fix. That is why every planter box we ship includes a standard 3-year warranty, extendable to 5 years at checkout.
What Our Warranty Covers:
- Manufacturing Quality: Guaranteed zero material defects, warping, or surface chips upon delivery.
- Structural Integrity: Engineered to resist knocks and impact along exposed edges and corners.
- Weather Resistance: High-performance finishes built to withstand years of harsh sun and heavy rain.
What Is Not Covered:
- Natural Aging: Minor surface fading or hairline weathering over long-term outdoor exposure.
- Trapped Moisture: Damage from leaving protective wrap on for more than 7 days post-delivery.
- Unsupported Base: Custom alterations, including external feet that do not provide full base support.
- Non-Standard Use: Modifying garden planter boxes into ponds or water features.
For Builders & Specifiers: If you are specifying balcony planter box or outdoor planter boxes ranges for major commercial projects, the 5-year extended warranty (available at checkout) offers essential long-term protection.

Trough & Rectangle Planter Boxes
Our most popular shape, trough and rectangle planter boxes are ideal for lining walkways, defining garden borders, or creating living privacy screens. Their elongated form makes them the natural choice wherever a space is wider than it is deep — think balconies, fence lines, or building frontages — where a cube or round pot would look out of place. Available in sizes from 850mm right up to 2000mm long, in every one of our exclusive in-house ranges.
Florence Trough
$195.00 – $695.00
Mykonos Troughs
$219.00 – $795.00
Long Troughs
$695.00 – $1095.00
Tall Trough
$329.00 – $1395.00
Cube & Square Planter Boxes
For a bolder, more architectural statement, cube and square planter boxes make striking focal points in any landscape. Unlike a trough’s linear form, their equal proportions work especially well as symmetrical pairs flanking an entrance, or as a single anchor piece in a courtyard or foyer. From the compact Cube 500 to our largest Cube 1000, there’s a size to suit any space — whether you’re softening a corporate lobby or defining a residential poolside.
Florence Light Concrete
$59.00 – $295.00
Alaska Off White
$59.00 – $295.00
Moscow Rendered Charcoal
$59.00 – $295.00
Monaco Rust
$59.00 – $295.00
Manhattan Cube
$59 – $1295.00
Tall Planter Boxes
Where floor space is limited but visual impact matters, tall planter boxes add height and drama without expanding their footprint. Ideal for framing entrances, filling awkward narrow corners, or creating a vertical green screen on a balcony, their raised profile also brings trailing or feature plants closer to eye level — something low troughs and cubes can’t achieve on their own.
Tall Trough
$329.00 – $1395.00
Florence Tall Square
$395.00
Florence Tall Round
$329.00 – $995.00
Milano Tall Trough
$495.00 – $749.00

History of Planter Boxes
Planter Boxes have a long history, dating back to ancient Egypt as early as 3,000 BC, where they were used to transport plants between locations. This was crucial for cultivating crops and ornamental plants in gardens. They utilised materials like terracotta, stone, metal, and wood, showcasing resourcefulness and adaptability.
The Renaissance saw a surge in the aesthetic use of planter boxes, as they became status symbols for the aristocracy, with elaborate designs and ornamentation. Sigma Planters offers a more functional, yet equally appealing, range of modern fibreglass landscape containers for building and horticulture planter box projects Australia-wide.
Ancient Egypt (c. 3000 BC): Egyptians were pioneers in using containers to move plants. This allowed them to cultivate food and create beautiful gardens, contributing to their agricultural and cultural development.
Ancient Greece and Rome: The Greeks and Romans further developed the use of planter boxes, often incorporating them into their architectural designs. They used materials like terracotta and stone, creating both functional and decorative elements in their gardens and public spaces.
Medieval Europe: During the Middle Ages, planter boxes were primarily used in monasteries and apothecaries for growing medicinal herbs and plants. These were often simple and functional, focusing on practicality rather than aesthetics.
Renaissance: The Renaissance marked a significant shift towards the aesthetic use of planter boxes. They became status symbols, with wealthy individuals commissioning elaborate designs and ornamentation to showcase their wealth and taste. This era saw the use of finer materials and intricate detailing, transforming planter boxes into works of art.
17th and 18th Centuries: The use of planter boxes expanded beyond the aristocracy, becoming more common in gardens of various social classes. New materials and designs emerged, reflecting the changing styles and tastes of the time.
19th Century: The Victorian era saw a surge in the popularity of gardening and ornamental plants. Planter boxes became increasingly elaborate and decorative, often incorporating cast iron and other ornate materials.
20th and 21st Centuries: Today, planter boxes are widely used in homes, gardens, and public spaces around the world. They come in a vast array of materials, styles, and sizes, catering to diverse needs and preferences. Modern planter boxes often incorporate sustainable materials and innovative designs, reflecting contemporary concerns about the environment and urban living.
Planter boxes have truly stood the test of time, evolving from simple tools for transporting plants to essential elements of garden design and urban landscaping. Their history reflects our changing relationship with nature and our ongoing quest to create beautiful and functional spaces.
