HPSO Garden Travel


Since 1998, HPSO members have traveled together to international garden destinations in England, Wales, Scotland, Ireland, France, Italy, the Netherlands, Belgium, Germany, Spain, Portugal, Madeira, South Africa, New Zealand, Japan, Denmark, Sweden, Slovenia, and Croatia.  New destinations - Southeast Australia and Tasmania -  are in the works.

Closer to home, our U.S. tours have featured gardens in Washington and California. The Puget Sound Islands tour series highlighted the gardens of Whidbey Island, Vashon Island, and Bainbridge Island.   Trips to the East Coast have also been popular. Recent destinations include New York City, the Hudson Valley, New England, Savannah and Charleston.


HPSO tours have distinctly garden oriented focus that supports our mission to provide great horticultural education opportunities for our members. Tours include a variety of cultural and historical sites that round out the landscape. Trips vary in duration, and they are filled with activities. HPSO tours represent an excellent value for the money.

Tour prices typically include double accommodations, motor coach and professional guide, tour gratuities, many meals, and admission to all gardens and other sites along the way. Participants are responsible for their own transportation to and from the tour's start and finish points, including airfare.

Tours are conceived, researched and led by HPSO members with experience in the relevant destinations. HPSO works through excellent international tour companies that are responsible for booking arrangements. Tours are open exclusively to HPSO members.


Tours are announced to members through emails, our member magazine the HPSO Quarterly, the HPSO Travel Interest Group (a.k.a. HPSO Travel Club), and on this web page.

HPSO Members who wish to have advance notice about tours must join the HPSO Travel Interest Group.  There is no fee for joining the group and no obligation to attend extra meetings. Travel Interest Group members receive early-bird registration privileges for HPSO tours. Contact the HPSO office to join and be on a travel-interest mailing list.

[Proposed]  "Escape to the Islands" (Oahu and Hawai'i)
Re-scheduled from 2022: September 2023

Join us for this "Escape to the Islands." Oahu and Hawai'i will give travelers a real sense of the biodiversity of this amazing island chain as we explore environments from dense, damp cloud forests to volcanic craters hosting dry-land succulents. Our visit includes large botanical gardens filled with exotic tropical specimens as well as lush private collector gardens. We will have a taste of the islands at some of the plantations featuring edible plants from coffee and chocolate to macadamias and pineapples. We'll talk to growers at nurseries devoted to hibiscus and orchids. The cultural crossroads found in Hawai'i will be evident in the gardens and historic sites from the Polynesian Place of Refuge near Kona, to the urban Chinese sites of Honolulu, to the Japanese gardens of the Valley of the Temples. All along our journey you will be treated to balmy island breezes and dramatic landscapes -- what better way to forget the rainy season is about to start back home.

[In planning]  Magical in the off-season: Enchanting Winter Gardens of England
February, 2023

Not even winter keeps the English out of the garden, and the wide array of gardening activities and sights in late winter is testimony to their tenacity.  Whether it be snowdrops festivals, witch hazel nurseries, a national collection of hellebores, or extraordinary gardens designed especially for winter, the gardeners of England make the most of the winter, and so does this tour!
