The ADEZZ Corten Steel NOOA Tall Square Planter forms part of the ADEZZ Corten Steel Architectural Planter range and targets customers who expect planting to perform a clear architectural role within a landscape. ADEZZ designed this range for high-end residential builds and professional, architect-led garden schemes where structure, material integrity, and long-term durability matter as much as visual impact. Inspired by Scandinavian design principles, the NOOA combines crisp, confident lines with subtly softened edges to create a planter that feels contemporary, purposeful, and timeless.

ADEZZ produces the NOOA Tall Square planter in one carefully considered size: L50cm×D50cm×H100cm. At one metre tall, the planter introduces strong vertical structure into a landscape. It lifts planting to eye level, allowing it to define entrances, frame doorways, and punctuate pathways with clarity and intent. Designers use its balanced proportions to complement modern architecture and establish a clear sense of scale, rhythm, and visual authority within the space.

The NOOA design incorporates an integrated ring at the base of the planter, which lifts it subtly off the ground. This detail sharpens the clean architectural aesthetic while allowing water to drain freely and air to circulate beneath the planter. By reducing standing moisture and improving airflow, the planter supports healthy root development and reliable long-term performance outdoors.

ADEZZ fabricates the NOOA Tall Square Planter from high-quality Corten steel, selecting the material for its strength, longevity, and evolving appearance. As the steel weathers, it develops a stable, self-protecting rust patina that gives the planter a rich, natural finish while shielding the underlying metal from further corrosion. It makes the planter exceptionally durable and well-suited to permanent outdoor use in the UK climate, particularly within contemporary and architectural planting schemes.

ADEZZ supplies the planter with drainage holes as standard to ensure dependable outdoor performance, and can omit drainage on request for interior use. ADEZZ manufactures every NOOA planter to exacting standards and backs it with a 5-year manufacturer’s warranty, giving confidence to both private clients and professional specifiers.

The natural Corten steel finish allows each planter to develop its own character over time, responding to its environment and planting in a way that feels authentic and grounded. For advice on lead times, installation, or suitability for your project, please get in touch with Riverhill Garden Supplies, who will be happy to help.

ADEZZ manufactures its Corten Steel planters from a specialist steel alloy that naturally protects itself from corrosion. When you place the planter outdoors, oxygen and moisture react with the steel to form a stable protective rust layer. This layer seals the surface and prevents deeper corrosion, keeping the planter strong and structurally sound for many years.

ADEZZ supplies all Corten Steel planters rust-free. Once you expose the planter to the elements, the weathering process begins and usually takes 4 to 5 months, depending on rainfall, temperature, and exposure. During this time, the colour changes from dark grey to warm orange-brown, then settles into the rich natural patina that designers and landscapers value.

As the steel weathers, rust runoff can temporarily stain paving or stone. You can prevent marking by placing the planter on gravel, soil or another permeable surface until the patina stabilises.

ADEZZ fits every Corten Steel planter with hidden feet and drainage holes. These raise the planter slightly above the ground, allowing air to circulate underneath and water to drain away freely. This design protects the base and supports healthy root growth.

Install the planter on a flat, solid surface and leave at least 1cm of space around the base so moisture cannot become trapped. Do not fit an overflow pipe, as standing water inside the planter can accelerate corrosion.

When you plant, add a 10cm layer of gravel to the base, cover it with a permeable membrane, then add your compost or growing medium. This setup ensures excellent drainage and prevents excess moisture from reaching the steel.

Avoid using hydro pellets, as they retain water and reduce drainage efficiency. For best results, avoid placing Corten Steel planters in areas with heavy salt exposure, such as near the coast.

Once the planter has developed its final patina, you can leave it to weather naturally, or apply a rust stabiliser (Owatrol) to lock in the colour and prevent loose rust from transferring.

With proper installation and drainage, ADEZZ Corten Steel planters deliver a robust, low-maintenance, weatherproof planting solution that performs beautifully year after year.

Stock and Lead Times

Riverhill Garden Supplies does not hold stock of the ADEZZ Corten Steel Architectural Planter range. These planters are supplied directly from ADEZZ in Holland. As a general guide, lead times are typically around 12–14 days, subject to availability.

As this is a new range with limited production volumes, availability can vary. For website consistency, these items may show as 'in stock', but if your project depends on a specific delivery date, we strongly recommend contacting us before ordering so we can confirm current availability with ADEZZ.

Storage and Delivery Flexibility

We understand that customers often work to project schedules and may need flexibility. One advantage of ordering from Riverhill Garden Supplies is that we can hold stock at our warehouse near Tonbridge, Kent, until you are ready to take delivery. We can order well in advance of your project and store the planters at no additional cost, giving you complete control over when your items arrive while allowing us to manage delivery from within the UK.

Customers are also welcome to collect their orders directly from our storage facility near Tonbridge, where we can load vehicles at short notice using one of our forklift trucks.

Riverhill Garden Supplies has been an ADEZZ reseller in the UK since 2011, and is proud to be one of the leading retail suppliers of ADEZZ garden planters nationwide. Our focus is on premium-quality garden products at the best possible prices for both the retail and garden professional, with exceptional customer service to match.

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 operate as more than just an online retailer. From our Kent warehouse we handle extra-large orders, bespoke fabrications and phased or delayed deliveries. We regularly store planters for customers until sites are ready and then arrange tailored deliveries to suit contractors, designers and private clients. We keep our approach simple by combining flexibility, practical problem-solving and clear communication.

Ordering direct from ADEZZ (Uden, Holland)
As a dedicated ADEZZ partner, Riverhill Garden Supplies combines deep product knowledge, accurate lead time advice and dependable customer service. We place orders directly with ADEZZ’s central warehouse in Uden, Holland, often daily during the high season, which allows us to secure stock immediately or instruct fabrication to begin without delay when ADEZZ needs to make a product to order.

Why we choose ADEZZ
We choose to list ADEZZ products because their European craftsmanship, precision fabrication and durable finishes meet the standards we demand for our customers. ADEZZ designs Aluminium and Corten Steel planters that combine clean contemporary design with professional-grade construction, making them suitable for everything from private gardens to large commercial landscapes.

Why ADEZZ Corten Steel stands apart
Corten Steel planters are one of the most poorly replicated products in the planter industry, with many cheaper alternatives failing to match proper steel grade, welding quality and long-term performance. ADEZZ uses high-grade 3mm Corten Steel (S355JOWP) and applies precision welding, accurate forming and strict quality control. This approach ensures every planter weathers evenly, forms a proper protective patina and remains structurally sound for decades. You can see the difference in the finish, strength and consistency of every ADEZZ Corten Steel planter.

How ADEZZ compares to UK-made alternatives
We regularly speak with UK manufacturers who offer Aluminium, Corten Steel, Fibreglass, Hardwood and coated steel planters that attempt to copy ADEZZ designs. None of them match the welding quality, surface finish or long-term durability that ADEZZ consistently delivers.

ADEZZ also holds an extensive range of stock at its warehouse in Uden, Holland, which allows us to offer fast, reliable order fulfilment across hundreds of sizes, colours and designs — something UK manufacturers simply cannot replicate. Over the years, we have imported planters from further afield. While this sometimes reduced costs, it also confirmed what we already knew: quality suffered. Inferior coatings, thinner steel and inconsistent fabrication produced planters that failed to meet our standards, especially in Corten Steel and Aluminium.

ADEZZ remains our benchmark
These experiences continue to reinforce our view that ADEZZ sets the benchmark for European-made planters. Their craftsmanship, consistency and reliability stand apart across Aluminium, Corten Steel, Hardwood, Fibreglass and coated steel ranges.

Experienced UK ADEZZ reseller
Whether you need modern Aluminium planters, premium Corten Steel designs or bespoke ADEZZ fabrications, Riverhill Garden Supplies provides one of the UK’s most experienced and reliable ADEZZ services, delivering clear advice, accurate lead times and dependable delivery from order to installation.

The tall, square proportions of the ADEZZ Corten Steel NOOA Tall Square Planter introduce strong vertical planting into both residential and commercial landscapes. Its height lifts planting to eye level and allows designers to frame entrances, doorways, gateways, and thresholds with confidence, where planting needs to create immediate visual impact and architectural presence.

Evergreen shrubs such as clipped yew, Ilex crenata, or Portuguese laurel suit the tall square format particularly well. They provide year-round structure, reinforce the planter’s crisp architectural form, and create a strong sense of balance and formality when used in pairs at entrances or along pathways.

For a softer contemporary look, architectural grasses such as Miscanthus, Calamagrostis, or

Pennisetum add movement and seasonal texture while maintaining a refined appearance. These

grasses contrast exceptionally well with the warm, evolving tones of Corten steel, enhancing the planter’s material character as the natural patina develops over time.

In sheltered or urban environments, small trees and bold foliage plants create strong vertical emphasis and visual interest. Bay trees, olives, or multi-stem shrubs break up hard landscaping effectively and introduce height without overwhelming the surrounding space. The generous internal volume of the planter supports healthy root development, allowing plants to establish quickly and perform reliably over the long term.

The integrated base ring and free-draining design actively promote healthy root systems and long-term planting performance, giving designers the confidence to specify a wide range of planting types for permanent outdoor installations and demanding landscape settings.
