TulipsGardening has come a long way since ancient civilizations began cultivating fruits and vegetables in the earliest forms of agriculture. As growing practices became more advanced and ornamental beauty surpassed utility, the wealthiest gardening enthusiasts pushed the limits of horticulture and design beyond simple red rose plants and other common flowers into uncharted territory. Centuries later, these techniques have led to some of the most awe-inspiring and beautiful gardens ever imagined.

Your backyard garden may be a great space for growing tomatoes and just because plants, but it likely doesn't hold a candle to some of these floral marvels. Here are some of the world's most amazing gardens.

Paleis Het Loo Gardens
Located in the Netherlands, Paleis Het Loo is the Dutch for "The Woods Palace." This regal 17th century garden was designed in an extraordinary symmetrical layout, according to PaleisHetLoo.nl. The layout displays a central axis with a number of parterres that feature neat box hedges in ornate scroll patterns - an effect known as "broderie parterres."

Many of the flowers and plants within the garden are non-native species that were collected by the West Indian and East Indian trading companies for the eventual joint rulers of England - William and Mary. In addition, caretakers shift the floral arrangements every season for an ever-changing aesthetic that emphasizes individual plants. A variety of beautiful fountains and statues of figures from Greek mythology enhance the natural elements of the garden.

The Garden of Cosmic Speculation
Flower arrangements and traditional gardening knowledge take a back seat to scientific inquiry in this one-of-a-kind landmark. Designed by Charles Jencks and his late wife Maggie Keswick in 1989, the Garden of Cosmic Speculation near Dumfries, Scotland, takes its inspiration from mathematical concepts, logic and geometric shapes. Along with unusual landscaping, sculptures such as the DNA double helix and the human brain encourage visitors (who are only allowed to visit one day a year) to probe life's deeper mysteries. Manmade lakes and strange mounds of earth also represent ideas and theories like the Fibonacci sequence of numbers and black holes, according to Kuriositas.com.

Versailles Gardens
King Louis XIV of France's world-famous palace at Versailles features one of the most captivating gardens ever created. Over the course of 40 years, starting in 1661, Andre Le Notre along with several other royal appointees designed the garden to the king's exact specifications. Along with magnificent flower beds, the garden includes the Orangerie, the Grand Canal and water fountains. Many royal events and parties were hosted at the palace gardens throughout France's monarchy, according to En.ChateauVersailles.fr.
