Take a tour of private and public gardens

NEW YORK — It's lovely to wander around a botanical garden on a spring day. But there's also something to be said for taking a close look, guided by an expert who can reveal a garden's secrets and point out the wonders that a casual stroll might miss.

Many botanical gardens offer guided tours, from a docent-led walk to see seasonal highlights, to ticketed tours focusing on some aspect of the garden's collection.

This spring, the Brooklyn Botanic Garden in New York is introducing several types of guided tours for groups of 20 or more.

"It's a way to really get in contact with the plants," said Mark Fisher, a curator at the Brooklyn Botanic Garden.

Walking through the garden's Steinhardt Conservatory greenhouse with Fisher on the "Meet the Curator" tour, you see things that you'd miss on your own.

He points out papayas clustered in a treetop; the architecture and artistry of a bonsai's pruned branches, and an orchid growing on a tree, its roots seemingly suspended in the air.

Brooklyn Botanic Garden spokeswoman Leeann Lavin said there's an increased interest in these types of tours thanks to "baby boomers who want to keep learning" and other visitors who are looking for a "more intimate experience" than just taking a walk on a nice day.

Historic gardens

Historic homes often have noteworthy gardens, too. No visit to Monticello, Thomas Jefferson's estate in Virginia, would be complete without a tour of the gardens. Jefferson grew hundreds of varieties of vegetables and fruits, and he filled his flower beds with a mix of European plants, like tulips, and native American specimens, including some collected by Lewis and Clark on their journey west. But part of the charm of the tour is learning that some of Jefferson's gardening experiments — including a vineyard and a dream of producing syrup from maple trees — failed.

Some locales organize tours of private gardens every spring, giving visitors a peek inside historic and often well-appointed homes that are not otherwise open to the public.

Newport, R.I., hosts a "Secret Garden Tour," June 15-17. Natchez, Miss., has a "Symphony of Gardens Tour" May 4-5. Atlanta's Gardens for Connoisseurs Tour, May 12-13, is a fundraiser for the Atlanta Botanical Garden. Historic Garden Week in Virginia, April 21-28, sponsored by the Garden Club of Virginia, features 30 tours around the state, from 18th-century James River plantations to walled urban retreats.

Most visitors to botanical gardens are day-trippers, but you can also plan a vacation around far-flung gardens. Elderhostel, a tour company that specializes in educational travel for older adults — (www.elderhostel.org or 800-454-5768) — offers trips to gardens in destinations ranging from Southern cities and the West Coast to England and New Zealand.

Adam Hurtubise, Elderhostel spokesman, says the number of garden programs offered by the company, along with enrollment, is on the rise. Also popular, he says, are Elderhostel programs with a service component, where participants can work on historic gardens in addition to taking a tour. One such Elderhostel program includes an option to work on the Victorian garden at the Emlen Physick Estate in Cape May, N.J.
