Designer Battle: The Aesthetic Signature of Nature

The classic with shine – Gergana

The variety that transformed the garden into an exhibition hall before we even knew the word ‘trend.’

Gergana – A traditional Bulgarian variety with a dark green glossy surface, cylindrical shape and dense, crunchy inside.

The fruits are up to 30 cm long, dressed in dark emerald suits with perfect shine. Like it has been made up of the latest generation of vegan cosmetics. The leaves are like fashion jewelry – big and strong even in windy conditions. But its real weapon is its versatility – it grows equally well in the greenhouse as well as outdoors.


The Long Lady – cm while Sandra F1

With cylindrical fruits with a maximum length of 35 cm and a weight of up to 350 g, it is the green manifestation of the supermodel.

Sandra F1 – an elegant greenhouse hybrid with a smooth surface, uniform thickness and a juicy, tender texture, ideal for year-round production.

Her shine is so intense you wonder if she’s wearing polish. And despite its impressive size, it retains its shape perfectly even when preserved.


Rebellious street style – Crocodiles

The new Bulgarian variety brings fresh breath with tender light green fruits.

Krokodilki – popular Bulgarian variety with light green colour, characteristic small spines and extremely juicy, aromatic centre.

Its studs are minimal – like a delicate accent on eco-vegan crocodile leather. The texture is a perfect balance between crunchy and juicy, as if it’s wearing a designer brand “Natural Freshness”. Its leaves are large and persistent, like green umbrellas of modern architecture.


Miniature Perfection – Testy King

At 10-12 inches in length, it is the cucumber equivalent of a luxurious “wallet” that preserves green freshness as a green means of natural wealth.

Testy King – an early variety with long, straight fruit, light to medium green color, smooth thin skin and a sweet, fresh flavor.

The smooth crust and compact size make it ideal for culinary performances – from canapés to mini sandwiches. Its design is so versatile that it can be combined with any serving style.


The Dutch avant-garde – Cervello RZ & Boncanale RZ

This pair grown in ‘Rosella’ greenhouses has futuristic forms.

Boncanale RZ is distinguished by long fruits that resemble green sculptures.

Boncanale RZ – premium cucumber variety grown in Rosella greenhouses with an ideal cylindrical shape and deep green colour, suitable for year-round cultivation.

Cervello RZ adds minimalist charm with perfectly clean lines.

Cervello RZ – a high quality variety grown in Rosella greenhouses with a dark green glossy surface and an excellent balanced taste without bitterness.

They show how it is possible for biology to create perfect geometry in nature while preserving the aesthetics of every millimeter of the crust.

Sustainability – a style that is tried and tested

Gergana – The Living Legend

This variety is like a vintage car – built to stand the test of time. It’s resistant to temperature contrasts, as if wearing an invisible thermal blanket. A growing season of 42 days makes it quick to respond to changes in the season’s schedule. Its foliage not only decorates but also protects from sunstroke.

Sandra F1 – The Armored Diva

Specially designed to withstand powdery mildew and virus attacks, it brings protection like an invisible shield. Its yields are like green armour against weak harvests. Interestingly, the more stressful the environment, the more intensely it flowers – a true phoenix bird among vegetables.

Crocodile – The Desert Nomad

Designed for the Bulgarian summer, this variety carries drought resistance in its DNA. Its leaves function as a built-in microclimate management system, maintaining optimum humidity even at 40°C.

Testy King – The Futuristic Stormtrooper

Carrier of a genetic shield against powdery mildew and mosaic viruses. A growing season of 35-40 days makes it a fast-responding garden specialist. Its compact size allows it to turn any sunny spot into a mini greenhouse.

Rosela’s Duo – The Ultimate Sustainability

This is where sustainability reaches a new level. Boncanale RZ carries resistant DNA against CGMMV, Cca, Ccu and Px6, as if the plants had gone through a combat readiness camp. Cervello RZ adds protection against CMV/CVYV, turning it into a green fortress.

Culinary Charm – The Art of Taste

Gergana – The Nostalgic Masterpiece

With the juiciness of childhood memories and zero bitterness, the taste is “as always”. Its aroma is like the score of summer evenings – a balance between freshness and sweetness. Ideal for classic salads where the taste should be reminiscent of the past.

Sandra F1 – Harmony in a Cylinder

Its taste is like a well-built cocktail – complex but balanced. It has a creamy texture that does not change even when cooked. This makes it a favourite for gourmet preserves where every bite should tell a story.

Crocodiles – Explosion of Freshness

The bright fruit hides a flavour bomb – crunchy sweetness with a slightly tart finish. The texture is fresh and melts on the tongue . An ideal choice for modern dishes where texture is as important as taste.

Testy King – The Intense Micro Art

Compact fruits concentrate the flavour like an essence. Its aroma is full-bodied and multi-layered. Perfect for molecular cuisine where a small amount should carry maximum effect.

Rosella Duo – Dutch Fusion

Where tradition meets innovation. Cervello RZ offers crystalline freshness with a hint of minerality, while Boncanale RZ adds a slight sweetness as a finishing flavour. These are notes that are like designer perfumes – complex, unexpected and long-lasting. More information – here.

Technological Revolution – Smart Agriculture

Gergana – The Intuitive Master

Her success is due to a genetic memory honed by generations of selection. She is like a living library of traditional practices adapted to modern conditions. She needs no elaborate care because she carries the wisdom of time in her DNA.

Sandra F1 – The Precision Hybrid

Designed for maximum productivity, it is the result of a mathematical calculation. Every aspect of its growth has been optimised, from the spacing of the leaves to the angle of the fruiting buds. This is farming turned into an art.

Crocodiles – The Bulgarian Phenomenon

This variety proves that local breeding can create competitive products. Its resistance to drought is the result of decades of observation of the Bulgarian climate. This is the vegetable that speaks our soil dialects.

Testy King – The Compact Genius

Designed for urban conditions, it demonstrates how productivity can be combined with miniaturisation. Its technology allows it to be grown even in terraces and balconies, making gardening a hobby for everyone.

Rosella Duo – Gardening From A New Generation

Here, technology exceeds expectations in a completely environmentally friendly way. The BonDefense Blue Leaf System is the result of decades of careful selection and traditional crossbreeding, where the plants’ natural defence mechanisms are enhanced without genetic interference.

The cucumbers grown at Rosella are the fruit of a harmonious union between precise Dutch breeding experience and Bulgarian soil wisdom accumulated over generations.

Innovation is also evident in the way they are cared for, with precise computer analysis of the microclimate and automated drip irrigation and feeding systems. The technology monitors the plants’ needs and optimises their environment, while preserving all the natural qualities of the fruit. This is farming that respects the natural cycle of the plant, while using the most advanced methods to create ideal growing conditions.

The Final

Having said all that so far, the question remains: which cucumber variety deserves to be the favourite?

But suddenly an unexpected entrant appears on the scene – SmartCucumber 3000, a robotic cucumber with artificial intelligence that promises a real revolution. Its concept is so futuristic it sounds like it came out of a sci-fi novel: personalized fruit that can change its taste according to the consumer’s mood.

Want a sweeter cucumber? No problem. Crunchier? One command and voila.

It all seemed too good to be true…

SmartCucumber 3000 – an innovative concept or science fiction? This is a joke to emphasise that even the most advanced technologies cannot replace the natural qualities and superior taste of cucumber varieties grown with care and tradition.

At the last moment, the SmartCucumber 3000 system gives an error. Instead of fresh cucumbers, it starts producing… pickled digital NFT cucumbers! Yes, you read that right – virtual cucumbers that can be bought and sold on blockchain platforms.

The audience first laughs, then applauds – but not because this is the future of vegetable farming, but because they realise something important: even the smartest technology cannot replace the true taste of nature.

And here comes the moment for reflection. Despite all the innovation, sustainability and design qualities, the winner in this race cannot be determined by yields or disease resistance alone. The real winner is the one who captures the palate and the heart.

Your taste can determine the true winner. The decision is in your hands – or rather, on your plate!
