Trees are vital for communities, both in urban and rural areas. In cities and suburban areas trees are often found in parks, along roadsides and surrounding playgrounds. They help to create a peaceful and protective environment. They also help to attract other wildlife to urban areas, again helping to sustain the urban environment in which the trees are planted. In cities, trees also help to provide shade and block out light, helping to cool streets and walkways. In addition to this, did you know that properties near mature trees are, on average 10% higher in value. Today we'd like to celebrate this amazing part of nature by showing you some of the most unique trees around the world.

Wisteria tunnels, Japan: Wisteria is a type of flowering vine that can be trained to take beautiful shapes. Every year, during the Wisteria Festival (Fuji Matsuri) in late April or early May, the 330-foot-long wisteria tunnels of Kawachi Fuji Gardens in Kitakyushu (on the island of Kyushu), and the enormous wisteria "tree" of Ashikaga Flower Park in Tochigi (on the island of Honshu), bloom to give us the most beautiful and colorful natural spectacle.

Giant Groundsels: Like an image out of Jurassic Park, these prehistoric Dendrosenecio kilimanjari are Giant Groundsels found atop Mount Kilimanjaro in Africa. As the highest mountain in Africa, Kilimanjaro itself is pretty outstanding. But as a free-standing mountain whose climate zones become progressively less like the ground-level landscape the further you ascend, Kilimanjaro is especially remarkable as an incubator for isolated, mutated, or rare species found almost nowhere else.

Rainbow eucalyptus, Papua New Guinea, Indonesia, and the Philippines: The rainbow eucalyptus is native to the rainforests of the Philippines, Indonesia, and Papua New Guinea. Their bright coloration appears on the tree's bark which peels off to reveal striking shades of green, purple, orange, and pink that are reminiscent of "your average four-pack of assorted highlighters," Australian Geographic explained. Some have been planted in the US, including Balboa Park in San Diego, California, as well as in specific spots Kauai, Maui, and Oahu, in Hawaii.

Great Basin Bristlecone Pines, California, Utah, Nevada: Found only in California, Utah, and Nevada, the Great Basin bristlecone pine is the oldest non-clonal species on the planet. Very resistant to harsh climate and growing conditions, it grows so incredibly slowly that it's able to stave off insects, fungi, rot, and erosion, allowing for a very long lifespan — some live over 5,000 years. The best places to see some is in Great Basin National Park, where there are three groves.

Dragon's blood trees, Socotra Island: Found on the Yemeni archipelago of Socotra in the Indian Ocean, dragon's blood trees get their name from the red sap they produce. Given the island's separation from the mainland about 20 million years ago, unique flora has been allowed to grow there undisturbed. According to National Geographic, 37 percent of the island's 825 plant species are found nowhere else in the world.

Avenue of the Baobabs, Madagascar: Madagascar is known for its otherworldly-looking giant baobabs, which you can easily find lining the road between Morondava and Belon'i Tsiribihina. The "Avenue of Baobabs," as it is known, is considered the most accessible place to see baobabs in Africa, and the most beautiful road in Madagascar. Baobabs can reach heights of nearly 100 feet, and live to more than a thousand years.

Bamboo forests, Japan: Like wisteria, bamboo is another plant that technically isn't a tree — it's grass — but when you're walking through a dense "forest" of them, you can hardly tell the difference. Sagano Bamboo Forest near Kyoto, Japan, is the most famous of them, but you can also find them in places like Maui in Hawaii.

Angel Oak, South Carolina: The famous angel oak is estimated to be between 300 and 400 years old. It's growing just outside of Charleston, South Carolina, in the Angel Oak Park on Johns Island. Angel oak is considered one of the oldest living oak trees east of the Mississippi River. Forty-thousand visitors come to the park each year to see this magnificent 65-foot-tall tree.

Blue jacaranda, South America: The blue jacaranda, a fast-growing ornamental tree native of South America, is known for stunning its bell-shaped violet flowers. The blue jacaranda was introduced in many other countries over time, including, Australia, Hawaii, Kenya, Tanzania, South Africa, and Zambia. While beautiful, the blue jacaranda is considered an invasive species outside a few places in South America.

Dark Hedges, Northern Ireland: This tunnel of beech trees in County Antrim, Northern Ireland, was planted back in the 18th century to impress those approaching the Georgian mansion, Gracehill House. Today, the Dark Hedges are well-known for being featured in HBO's Game of Thrones, where they stand in as the Kingsroad, a road with Castle Black in the North at one end and King's Landing in the South at the other.

Cherry blossoms, Japan: From the German city of Bonn, to the grounds of the Imperial Palace in Tokyo, to DC's Tidal Basin, cherry blossoms mark the arrival of spring. The blooming of the cherry blossoms is nothing short of a phenomenon in Japan, with blossom-themed festivals held in many parks around the country. Similarly, in Washington, DC people come from all over for the National Cherry Blossom Festival each spring.

Dead Vlei trees, Namibia: Sossusvlei in the Namib Desert is home to the Dead Vlei trees, which somehow manage to be both dismal and beautiful. The clay landscape was once in the floodplain of the Tsauchab River, but when the climate dried up some 900 years ago, sand dunes got in the way of the river flow and the trees all died. It's too dry for trees to decompose, so they have been burnt black by the sun, and now form a forest of scorched trees, some over 1,000 years old.

Redwoods, California: The tallest trees in the world, California's coast redwoods, grow on a narrow sliver of land on the California coast, from south of the Bay Area up to the border with Oregon. There are many parks in California where visitors can see redwoods for themselves, including Redwood National Park, Muir Woods National Monument, and Calaveras Big Trees State Park. California's coast redwoods can reach a height of 367 feet and a base width of 22 feet.

Banyan trees, India: Banyan trees are short and stout trees native to India. Their particularity, what makes them unique trees, is their aerial roots that develop from their branches and drop to the ground to grow new trees. This growing technique is the reason why Banyan trees have such wide trunks — it's actually several trunks that grow closely together. One of the best-known banyan trees is the Arbol del Tule, a tree estimated to be between 1,433 and 1,600 years old in the Mexican state of Oaxaca, whose trunk has the widest-known circumference in the world at 119 feet (according to the Guinness World Records in 2005).

Giant sequoias, California: Sequoia & Kings Canyon National Parks in California are home to the largest trees in the world, by volume. "General Sherman" is the largest tree on Earth by trunk volume, and draws hundreds of thousands of visitors a year to the park's Giant Forest that is home to 8,000 sequoias. Sequoias can reach the age of 3,400 years old.

Ta Prohm, Cambodia: Ta Prohm is one of the many beautiful temples in Siem Reap, Cambodia. Its popularity comes from the ceiba and fig trees that are slowly reclaiming the centuries-old stonework, their roots encroaching on the ruins, in a scene that shows the power of nature. You can wander through the temple's corridors and explore the more natural maze created by the expanding roots.

Ponderosa pines, Utah: The Ponderosa pine is one of the American Southwest's tallest trees, growing to heights up to 200 feet. The Ponderosa pine can be seen throughout western North America, but are most famous for appearing in Ponderosa Canyon in Utah's Bryce Canyon National Park. The canyon is named for the unique trees, which can be found on the canyon floor. If you're not sure you've run into a Ponderosa tree, try smelling its bark. According to the National Park Service, "Ponderosa Pine bark smells like vanilla or butterscotch."

Joshua trees, American Southwest:The American Southwest's famous Joshua trees are not actually trees: They are agave, which are a type of succulents, i.e. a plant that's able to retain water in its stems. Joshua trees have spines and produce white-green flowers at the tip of their branches in the spring. Joshua trees are found mostly in the Mojave Desert, especially in Joshua Tree National Park in California, and have become one of the region's most defining features. According to the NPS, you may also find them "growing next to a saguaro cactus in the Sonoran Desert in western Arizona or mixed with pines in the San Bernardino Mountains."

Spider trees, Pakistan: When wide-scale flooding hit Pakistan in 2010, spiders fleeing the rising waters took to the trees and cocooned them in spiderwebs. Despite their forlorn appearance, there is a silver lining. According to Wired in a 2011 piece, Britain's department for international development found that areas where spiders overtook the trees have experienced fewer malaria-spreading mosquitoes.

Buttress roots: These roots, known as "buttress roots," can be found on many different species of tree, although they are more commonly seen on trees in tropical rainforests. They are a form of widening and spreading of the trunk that act to help large, top-heavy trees stay upright.

Japanese maples: Japanese maples are native to Japan, Korea, China, Mongolia, and Russia, and have also been grown in temperate climates around the world since the 1800s. Unlike other plant species, the Japanese maple varies in leaf-form, color, and tree shape, making each one unique. There are more than 1,000 varieties of Japanese maple in the world today.

Axel Erlandson's art trees, California: The strangest trees you'll ever see aren't ones you'd find in the wild. They were created by the Swedish-American farmer Axel Erlandson, who engaged in the hobby of "tree shaping" and even opened an attraction called "The Tree Circus" in 1947. Twenty-five of his "Circus Trees" are still alive today at Gilroy Gardens Family Theme Park in Gilroy, California. If you can get past the fact that these tree formations aren't natural, but instead the result of shaping and grafting techniques, visiting the park is a cool experience.

The Circus Trees were originally grown and created by Axel Erlandson, born in 1884 to Swedish parents. A wonder-work of Axel Erlandson, the basket tree and the Tree Circus has featured in Ripley's Believe it or Not for over twelve times. Axel Erlandson – a Swedish-American horticulturist hand-grafted trees as a hobby to form unusual patterns like this basket tree. His indulgence resulted in the creation of a whole exhibition called the 'Tree Circus' that was opened to public in 1974. Shortly before his death, he sold his collection that was later included in the Gilroy Gardens – a garden-themed family park in Gilroy, California.

Banyan Tree Roots in Hong Kong: Banyan trees are immediately recognisable for their spindly aerial roots, which cast outwards in search of water and nutrition. When the root finds a suitable source, either in the soil or another tree, it becomes a thick, woody trunk. This is what allows the banyan to grow in varied conditions, which is why they are the most prominent forms of greenery in the hilliest and most densely packed parts of Hong Kong. Jim has counted more than 1,100 trees growing from the sheer surfaces of masonry walls on Hong Kong Island.
