The best botanical gardens across the world create an organically formed art exhibit. Stressed? Take a walk. Reconnect with nature. Stop to smell the roses. Flowers provide a serene calming from the array of colors to the scents and sounds of the birds and trees. Spend some time marveling at the sensuous flora and fauna and all your problems will seem a lot more trivial.

Brooklyn Botanical Garden

Sometimes beauty can be found in the most unlikely places, like the backyard of the concrete jungle of New York City, so far removed from the city, you may even forget you're there. This 52-acre display is located in the heart of Brooklyn and is home to over 12,000 species of plants. There is also a Bonsai Museum on premises, and the not to be missed Cherry Esplanade's blossoming cherry trees. Look around for rabbits and turtles that call these gardens their home.

Jardin Botanique du Montreal

Winters in Montreal can be harsh, but that is no problem for the 22,000 plant species at the Jardin Botanique du Montreal. This garden blends indoor and outdoor collections that are equally captivating, making it a great place to visit no matter the weather. The 185 acres include an outdoor arboretum, an indoor insectarium with 160,000 specimens, Chinese and Japanese-style gardens, and the First Nations Garden, where guides explain traditional cultivation of crops like corn and squash. The Chinese Dream Lake Garden is a truly unique sight, modeled after gardens from the Ming dynasty. The materials needed to build this garden were shipped directly from Shanghai and took 50 Chinese craftsmen six months to assemble.

Reid's Palace

The botanical garden in Madeira, Portugal, is a one-of-a-kind place. The gardens are the grounds of the Reid's Palace hotel, a famous luxury hotel that sits on cliffs overlooking the Atlantic Ocean. An already naturally beautiful vista is made even more so by the 10 acres of semi-tropical plant life that surrounds the hotel. Portugal's climate makes this garden burst with color year-round and the trees come from all over the world, including Brazil, Japan, Australia, and Africa. There for admiration are flowering shrubs such as hibiscus, mimosa, wisteria, and more. The "Garden of the Atlantic" also hosts tango lessons in the bar at the hotel every Saturday.
