This blooming vine is from the Philippines and grows in tropical rain forests.

It’s a perennial evergreen vine and a member of the legume family.

Because of excessive timber harvesting in its native land, it’s considered endangered in its original habitat, but because it’s grown as an ornamental in many tropical and subtropical regions, it’s considered safe from extinction.

The shape of its beautiful aqua-blue flowers evolved in response to the bats that pollinate it.

Grown in many botanic gardens around the world, this vine took almost 10 years to bloom in the tropical greenhouse of one well-known garden, but the flower display was certainly worth the wait.

Welcome to the first Gardens Around the Globe feature highlighting the Berlin-Dahlem Botanic Garden and Greenhouses. One day of traipsing through the 107-acre site wasn’t nearly enough.

I had the chance to visit the beautiful Botanischer Garten in Berlin, Germany, one cool and overcast September day in 2008 and practically wore myself out trying to see it all.

The garden is surprisingly expansive for being in the middle of the city. It includes more than 18,000 cultivated species of plants and turn-of-the-century greenhouses that look like churches made of shimmering glass.

This photo shows the classical pattern of an Italian garden. The greenhouse in this picture was undergoing a major restoration at the time, so I wasn’t able to tour the inside. Just another reason to plan a return visit to Berlin.

Plantsman Tony Avent of Plant Delights Nursery in Raleigh, N.C., has created a beautiful botanical display garden filled with rare plants and animals.

The early morning photo shoot, part of the Garden Writers Association Symposium, was the perfect way to start the day. Buses began arriving at the Plant Delights Nursery around 7:30 and we were treated to a lovely breakfast before we hit the trails.

Plant Delights Nursery is more than a place to purchase plants. It’s a five-acre display garden with more than 17,000 different plant specimens. It would be impossible to see them all, especially since the garden is always changing.

The gardens began simply on a flat suburban site, but it has grown to become a showcase for rare and unusual ornamental plants.

Of course I was drawn to the plants in the Southwest Garden that featured delicate cacti planted with large agave, but I was equally taken with the Alpine Garden and Woodland Garden, too.
