The ADEZZ Aluminium EXTEND Planter offers a clean, architectural aesthetic that suits both traditional and contemporary garden designs. Its distinctive double-folded upper edge creates a crisp, timeless profile, while the expertly fabricated aluminium body provides exceptional strength with remarkably low weight. As one of the long-standing UK resellers of ADEZZ products, Riverhill Garden Supplies is proud to offer this premium planter range, trusted by garden designers, landscapers and architects nationwide. Made from 3mm aluminium and finished with a premium, scratch-resistant powder coating, EXTEND Planters are engineered to withstand all weather conditions. They will retain their elegant appearance for many years.

Now available in four versatile sizes — 120cm × 60cm (H), 100cm × 75cm, 80cm × 80cm, and 70cm × 110cm — the EXTEND Planter offers impressive flexibility for modern landscaping. Use them as standalone features, frame a doorway, or group them with other ADEZZ Aluminium Planters to create structure, rhythm, and impact in any garden layout. The EXTEND range is suitable for high-end residential projects as well as commercial and public-realm schemes, where durability, clean lines, and a premium finish are essential.

These planters do come at a premium, but with good reason. Very few fabricators can replicate this level of craftsmanship or the EXTEND design signature. This range represents ADEZZ at their best — an actual demonstration of why they are market leaders in large contemporary aluminium planters, setting the standard for build quality, durability, and design precision.

Fabricated from corrosion-resistant aluminium, the EXTEND Planter, designed for year-round outdoor use, even in freezing temperatures, undergoes a multi-stage finishing process: the metal, roughened for superior adhesion, is coated with a robust adhesive primer, and finally finished with a hard, scratch-resistant topcoat, ensuring a flawless, long-lasting finish.

Drainage holes and subtle 18mm feet come as standard, allowing the planter to sit slightly elevated for optimal water flow. Although aluminium is naturally long-lasting and low-maintenance, Riverhill also supplies professional maintenance products to help keep your planter in perfect condition.

You can now order the ADEZZ Aluminium EXTEND Planter online in our 4 standard RAL colours and 10 new trend colours, all available with no start-up fee.

Order online or by telephone. Our office is open Mon-Sat 8 am-10 pm including Bank Holidays except Christmas Day.

Material Thickness

The standard thickness of ADEZZ Aluminium Contemporary Planters is 3mm.

Standard Colours

ADEZZ Aluminium Planters are available in four standard colours, carefully selected to complement a wide variety of planting schemes and landscape styles:

• RAL7016 Anthracite Grey – A contemporary, versatile tone that pairs beautifully with silver foliage, green planting, and modern hard landscaping.
• RAL7021 Black Grey – By far the most popular and neutral finish, offering outstanding flexibility across both traditional and contemporary settings. It harmonises effortlessly with almost any planting palette and architectural style.
• RAL9005 Jet Black – A bold, architectural colour that provides strong contrast and suits minimalist or statement designs.
• RAL9016 Traffic White – Clean, bright, and modern. This crisp finish complements light, coastal, or minimalist gardens and enhances green or dark-leaved planting for a fresh, sophisticated contrast.

Each finish is professionally powder-coated to ensure long-lasting protection and a refined, uniform appearance.

New ADEZZ Trend Colours Available to Order Online at No Extra Cost

In addition to the standard ADEZZ Aluminium Planter colours that Riverhill Garden Supplies has long offered online, the full range of ADEZZ Trend Colours can now also be ordered directly through our website, at no additional cost. Inspired by natural materials, these ten RAL Trend Colours introduce warm, earthy, and organic tones that blend harmoniously into both contemporary and traditional garden designs.

This expanded colour range allows customers to create a more refined and personalised finish for their ADEZZ Aluminium Planters, with every option available to order online through Riverhill Garden Supplies — your go-to for everything ADEZZ in the UK.

• RAL7006 Beige Grey – A soft, stone-inspired grey with warm undertones, ideal for natural planting schemes.
• RAL1015 Light Ivory – A pale, creamy finish that pairs well with Mediterranean or coastal designs.
• RAL6013 Reed Green – A gentle, muted green that complements foliage and soft planting palettes.
• RAL7022 Umbra Grey – A deep, warm grey that sits perfectly between modern and rustic styles.
• RAL7031 Blue Grey – A cool, subtle tone with a hint of blue, enhancing silver and green planting.
• RAL7044 Silk Grey – A soft, elegant grey that suits minimalist and neutral garden schemes.
• RAL8004 Copper Brown – A rich, warm brown reminiscent of terracotta, ideal for earthy planting and brickwork settings.
• RAL8019 Grey Brown – A deep, sophisticated brown-grey that works beautifully in contemporary spaces.
• RAL8024 Beige Brown – A warm, natural tone inspired by clay and sand, perfect for soft landscape palettes.
• RAL9002 Grey White – A gentle, off-white with a subtle grey hue, creating a light, refined contrast in modern gardens.

All Trend Colours are finished to the same high ADEZZ standard with a durable, powder-coated surface for long-term outdoor performance. These colours are particularly suited to projects aiming for natural harmony and subtle contrast rather than bold architectural statements.

Riverhill Garden Supplies — ADEZZ Specialist (UK)

In 2011, Riverhill Garden Supplies became the first business in the UK to retail ADEZZ products through the then sole importer, The Pot Company. Since 2019, we have worked directly with ADEZZ to supply their full range to customers across the UK.

More than just an online retailer

We are more than just an online retailer — with our Kent warehouse and hands-on logistics, we can handle extra-large orders, bespoke pieces, and phased or delayed deliveries. We regularly store planters for customers until sites are ready and then arrange tailored delivery to suit contractors, designers, or private clients. Our approach is simple: a flexible, can-do attitude and clear communication.

Ordering direct from ADEZZ (Uden, Holland)

As a dedicated ambassador for the ADEZZ brand, Riverhill Garden Supplies combines unrivalled product knowledge with accurate lead time advice and dependable customer service. We place orders directly with ADEZZ’s central warehouse in Uden, Holland — and every day during high season — allowing stock to be secured immediately, or, for made-to-order products, fabrication to begin without delay.

Why we choose ADEZZ

We choose to list ADEZZ products because their European craftsmanship, precision fabrication, and durable powder-coated finishes meet the standard we want to offer to our customers. ADEZZ Aluminium Planters are lightweight yet robust, built to last, and suitable for both contemporary and traditional settings.

How ADEZZ compares to UK-made alternatives

Often we are approached by UK suppliers who ask us to resell their own ranges of planters — Aluminium, Corten Steel, Fibreglass, Hardwood, and Coated steel — many of which attempt to replicate ADEZZ designs. However, none have matched the quality of welding, finish, or long-term durability that ADEZZ consistently achieves. Just as importantly, no UK manufacturer can compete with the extensive inventory held at ADEZZ’s warehouse in Uden, Holland, which enables quick, reliable order fulfilment.

Over the years, we have even imported our own planters from further afield. While this occasionally helped reduce costs, it also confirmed what we already knew: the quality suffered. Inferior coatings, thinner materials, and less precise fabrication led to products that did not meet our standards.

From our own experience within the industry, this is most evident with Corten Steel and Aluminium products in the UK, where local fabrication often falls short in both finish and consistency. ADEZZ, however, are very strong on quality control — ADEZZ workmanship, attention to detail, and consistency set them apart from every other manufacturer we have dealt with.

ADEZZ remains our benchmark

These experiences have only strengthened our confidence in ADEZZ as the benchmark for European-made planters — a brand whose craftsmanship, precision, and reliability, in our opinion, remain unmatched across Aluminium, Corten Steel, Hardwood, Fibreglass, and Coated Steel planter ranges.

Experienced UK ADEZZ reseller

Whether you are sourcing modern Aluminium Planters, custom-made fabrications, or need professional guidance on ADEZZ colours, finishes, and lead times, Riverhill Garden Supplies remains one of the UK’s most experienced and reliable ADEZZ resellers — offering a smooth, dependable service from order to delivery.

Planting Ideas for the ADEZZ EXTEND Planter

The ADEZZ EXTEND Planter has a refined, architectural form with its distinctive double-folded top edge and clean linear proportions. This makes it exceptionally versatile, working beautifully with structured, contemporary planting as well as softer, naturalistic schemes. Its generous depth and elegant profile suit statement trees, clipped evergreens, ornamental grasses, mixed shrubs and wildlife-friendly native plants.

Evergreen structure

The crisp lines of the EXTEND Planter pair perfectly with clipped, architectural evergreens such as Ilex crenata balls or columns, Portuguese laurel domes, upright yew (Taxus) and narrow forms of Thuja occidentalis such as ‘Smaragd’. These shapes create a calm, modern silhouette that emphasises the planter’s folded edge and gives year-round structure.

Architectural grasses

Tall, flowing grasses contrast beautifully with the planter’s strong geometry. Miscanthus ‘Morning Light’, Calamagrostis ‘Karl Foerster’, Stipa tenuissima and Pennisetum ‘Hameln’ all bring movement and softness, introducing texture and seasonal interest while keeping the overall look clean and contemporary.

Mediterranean feature planting

For warm, sculptural planting with a modern feel, the EXTEND Planter is ideal for compact olive trees, Phormium in contrasting foliage colours, dwarf palms and Pittosporum varieties such as ‘Golf Ball’ or ‘Tom Thumb’. Mediterranean foliage sits naturally with the EXTEND’s contemporary aesthetic and works particularly well on terraces, balconies and sun-exposed courtyards.

Contemporary shrub combinations

Low-maintenance evergreen mixes offer year-round texture and colour. Nandina domestica, Hebe ‘Green Globe’, Choisya ‘White Dazzler’ and Euonymus japonicus varieties combine beautifully in the EXTEND, creating a smart, welcoming feel with minimal upkeep. These mixes suit both high-end residential schemes and commercial entrances.

Seasonal displays

The clean, straight edges of the EXTEND make even simple seasonal arrangements look elegant and intentional. For winter, consider heuchera, skimmia, violas and ivy to give colour and structure in the colder months. In summer, hydrangeas, salvias, gaura and trailing verbena provide flower, movement and a relaxed, contemporary feel. A seasonal refresh once or twice a year keeps the planter looking beautifully curated.

Small ornamental trees

The EXTEND is well-suited to specimen trees for entrances, terraces or courtyards. Amelanchier lamarckii, Acer palmatum (in sheltered positions), Prunus ‘Amanogawa’ and Sorbus ‘Autumn Spire’ all work well, adding height, structure and a dramatic focal point while sitting comfortably within the planter’s architectural lines.

Herb or aromatic planting

For relaxed, fragrant planting near seating areas, the EXTEND Planter is perfect for lavender, rosemary, thyme, sage and compact oregano varieties. Their scent and textured foliage soften the sharp aluminium lines without losing the crisp, contemporary look, making them ideal for patios, roof terraces and outdoor dining spaces.

Indigenous (UK-native) planting ideas

The EXTEND Planter also suits naturalistic, wildlife-friendly planting using British native species. These provide biodiversity benefits and pair beautifully with the planter’s sleek contemporary form.

Birch (Betula species) is light, elegant and full of movement, while rowan (Sorbus aucuparia) offers blossom, berries and excellent wildlife appeal. Hawthorn (Crataegus monogyna) is tough, textural and packed with seasonal interest, giving a relaxed, hedgerow character in contrast to the aluminium.

Native roses such as Rosa rugosa and Rosa canina provide scented flowers and bright hips, while native ferns (Dryopteris and Athyrium) create lush texture in shade. Heather and bilberry can be used to evoke a low, naturalised woodland-edge feel, and a native meadow mix of grasses and wildflowers offers soft, ecological planting that supports pollinators. Compact hazel or spindle add brilliant autumn colour and strong wildlife value, looking especially striking against the EXTEND’s clean aluminium finish.
