The avant garde garden design movement dispenses with traditional conceptions of gardens in favor of a more sculpture-like approach. These "Supertrees", designed by Grant Associates, are found in Gardens by the Bay in Singapore. The Supertrees, conceived to be like mature trees "without the wait", are the height of a tall building and support a living "skin" of plants.

When confronted with the plantless expanse of a former cornfield surrounding his newly built house, Pearl Fryar decided to buy some shrubs. 30 years later, Fryar's 150-plus topiaries have taken the form of astounding, free-flowing, abstract, sometimes whimsical artistic creations.

The Australian Garden in Melbourne, Australia, is a botanical garden where around 3,000 species are able to flourish due to its optimum climate. Designed by Taytlor Cullity Lethlean Landscape Architects with Paul Thompson, it is intended to engage and inspire visitors rather than simply showcase a collection of plants.

This may look like a tropical swamp, but it is part of the eccentric and eclectic Lotusland gardens in Santa Barbara, California. Created by the flamboyant Polish opera singer Ganna Waska, it features this water garden, created in an old swimming pool. Asian lotuses were planted in "a tribute to Eastern philosophy".

The Huntington Gardens in San Marino, California, are home to one of the most extensive cultivated collections of botanical exploration in the world. The collection includes two-thirds of the world's known species of aloe. The Desert Garden, pictured, includes rare golden barrel cacti, the ribs of which expand and contract as they store and use water.

The Oasis d'Aboukir in Paris, France, is one of French botanist Patrick Blanc's most renowned vertical gardens. He has been making them for more then three decades, combining his deep botanical knowledge with a near-evangelical urge to bring gardens into the most inaccessible parts of the city. This example contains 7,600 plants, taken from 237 species.

Olinda, in Victoria, Australia, is the personal garden of Philip Johnson, who won Best in Show at Chelsea 2013. It is planted on an extremely steep site, with an angle of 23 degrees, and seems to defy erosion. Every drop of rainwater is captured and "endlessly recycled", and during the bushfire danger season, an elaborate computer-driven system triggers hidden sprays when the risk of fire is high.

The Central Garden at the Getty Center in Los Angeles, USA, is a dramatic Modernist experiment which moves garden design away from established convention and towards a conception of garden-as-sculpture. The designer, Robert Irwin, said: "After a certain time, once the garden got going, it changed all the rules."

When it comes to the marriage of artistic creation and garden design, what survey would be complete without mention of Monet's famed Water Garden? Inspired by his interest in Japanese woodcuts, Monet regrouped plants such as water lilies, irises and willows that grew naturally near the Epte River to create a vision of paradise that he could paint again and again.
CNN  — 

When is a garden not a garden? When it’s an avant garden. Designers of the past – who were concerned with verdant lawns, traditional flowerbeds and tasteful ornaments – would barely recognize the experimental gardens of today.

“Garden design has always been quite a traditional discipline, says Madison Cox, a garden designer and part of the team behind a new book, The Gardener’s Garden.

“Gardens are in a constant state of flux, and you can only do what the plants allow you to do. So it changes less rapidly than painting, sculpture or architecture, as it takes longer to experiment.”

Plant vocabulary

There have been other restrictions, too. In the past, garden design was limited by the plants available, as it was difficult to access plants that did not grow indigenously. But now, says Cox, the “plant vocabulary” has increased.

“Go to any garden center in England, Italy, America or elsewhere, and you’ll find plants from all over the world,” he says.

This – together with the influence of radical breakthroughs in the disciplines of painting, sculpture and music – has allowed a new generation of gardeners to create spaces that owed more to the imagination than tradition.

The birth of a new experimental art form

It started with experiments like Lotusland, an extravagant garden in Santa Barbara, California that was created in the latter half of the 20th Century by Madame Ganna Walska, an eccentric opera singer. It contains exotic plants from all over the world, set in fantasy contexts.

“It’s completely mad,” says Cox. “The section called the Blue Garden, for instance, has many blue plants and blue-colored slag from a Coca-Cola bottling plant on the ground. The effect is this weird, underwater, blue light, that is at the same time eerie and soothing.”

Similarly, Marjorelle – a public garden in Marrakech, Morocco, that attracts about 730,000 visitors a year – showcases plants that are almost completely devoid of vivid color, and resembles a world of grays, light greens and pale blues.

“The only color comes from things that are not natural, like painted surfaces and pottery,” says Cox.

Taking design to the next level

In Kent, England, the garden that belonged to movie director Derek Jarman eschews grass and traditional trees to embrace flotsam, weeds and found objects, creating a space that is in many ways closer to a movie set than a garden.

Modern experimental designers have been taking things to another level. The Red Sand Garden in the Royal Botanic Gardens in Melbourne, Australia, resembles a martian landscape, complete with rock circles, curving escarpments and striking forms and foliage.

However, modern avant garde designers are not completely free from all constraints. “In today’s world, we have other pressing environmental issues, such as water conservation,” says Cox. “Designers need to consider what is appropriate to the specific climatic conditions they are working in. This is of vital importance.”

The heart of any garden

Ultimately, he says, a garden is a garden if it represents a retreat from the world.

“In recent years there has been an explosion of creativity,” he says, “but we have never lost that sense that garden is a paradise, a retreat from the world, and an alternative to our normal surroundings and chaotic lives.

“That has always been the point of a garden, and that will never change.”
