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 and Japan. New destinations - Denmark, Sweden, and Australia are in the works.

Closer to home, our U.S. tours have featured gardens in Washington and California. The Puget Sound Islands tour series has 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, 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 earlybird registration privileges for HPSO tours. Contact the HPSO office to join and be on a travel-interest mailing list.

 "The East of England & the Thames River Valley"
July 4 - July 15, 2019

Our Quint[essential] England for Gardeners series continues in another region with this tour - the East of England plus the Thames Valley. The East of England is one of nine official districts, comprising the counties of Hertfordshire, Bedfordshire, Cambridgeshire, Norfolk, Suffolk, and Essex. To these, we add Oxfordshire, Buckinghamshire, Rutland, and a bit of Lincolnshire. In ancient times, this area was the most populous in England and, as such, it is a land filled with history. Today, it is mostly a rural landscape dotted with market towns, churches, and picturesque villages. It also has one of best areas for viewing wildlife.
Join us on this garden-intensive tour as we explore this wonderful part of England. We include visits to famous places such as Blenheim Palace (birthplace of Winston Churchill) and the Queen’s country residence of Sandringham House. We visit fabulous gardens such as Beth Chatto’s Garden and the Old Vicarage of East Ruston - a “bucket list” garden not to be missed! We enjoy lunch and bird watching while cruising on The Broads. We visit some of England’s prettiest villages and cathedrals. We include seaside hotel accommodations.   Our summer tour is the perfect time to visit gardens as we travel around the East of England and the Thames Valley.

 "Past as Prologue: The Gardens of Berlin, Potsdam & Surrounding Regions"
September 2-14, 2019


Known for its tumultuous and often tragic history, and renowned as a center of education and culture, Berlin and its surrounding regions also possess a proud gardening tradition, with expensive Prussian palaces and gardens, some of Europe's earliest public parks, and the nurseries of pioneering horticulturists.  The region is now at the forefront of environmentally sensitive and sustainable gardening movements.  This13-day, 12-night tour takes members on a fascinating journey through a dynamic region, visiting public parks, private gardens and other beautiful and engrossing gardening and horticultural sites.  On display, too, are centuries of German history, and the tour includes visits to landmarks stretching from the Reformation through to the 21st Century.  Everywhere, tour members meet locals whose passion for gardening transcends the changes and challenges they have encountered.

Please check with Jim Rondone for space availability on this tour.

 "Springtime in New Zealand: A grand adventure to the gardens & natural wonders of the North & South Islands"
October 8 - November 2, 2019 


New Zealand is a land of stunning beauty and diversity.   With volcanic peaks and geothermal hot spots on the North Island to the uplifted "southern Alps" and glacial plains of the South Island, it is filled with contrasts.  From tip to tip, New Zealand is roughly the length of Portland to southern California, having a similar range of climates but in "reverse" since it lies in the southern hemisphere.  The northern tip enjoys a definite subtropical climate (similar to San Diego) while the extreme southern end is a much cooler temperate one (with alpine areas, too).  With all of this diversity comes a wide range of garden styles featuring a wide range of plants - both native and exotic!
Join us on one or both of our tours as we explore the gardens and natural wonders of these two main islands of New Zealand - the North Island and the South Island.  Included in our visit are the very best private and public gardens.  We'll also enjoy fabulous sights, geologic wonders, country towns, a Maori cultural performance, wine tours and tasting, and cruises on the Milford Sound, the Bay of Islands, and across the Cook Strait.  We'll do some shopping, see unfamiliar plants, make some new friends, enjoy the camaraderie of other gardeners, and meet the wonderful and friendly people of New Zealand.  It will be a grand adventure in New Zealand in the springtime!

"A Nordic Adventure: Gardens & Castles of Denmark and southern Sweden"
May 26 - June 7, 2020

SORRY. THIS TOUR IS NOW FILLED.   Contact us if you would like more information or if you wish to be placed on the waiting list.

Embark with HPSO on a new adventure to two nations often cited as the happiest in the world. Our tour begins in Copenhagen and ends in Stockholm. We explore gardens and sites of interest on two of Denmark’s main islands, Zealand and Funen, before we cross the Øresund straight into Skåne, a former part of Denmark that became Sweden’s most southern province by the treaty of Roskilde in 1658. After we enjoy Skåne, we travel along the west coast of Sweden, including the cities of Helsingborg and Gothenburg, before we take a scenic train journey across the country to Stockholm, the capital city. 

The Atlantic Gulf Stream provides northern Denmark and southwestern Sweden with a fairly mild climate, allowing beautiful gardens to thrive. Included on our tour are visits to the best private and public gardens in this region plus Tivoli Gardens and the Malmo Flower Festival which is held just every two years. Also included are visits to palaces, castles, historical sites, and various museums such as the Vasa Museum, the Viking Ship Museum, Hans Christian Andersen Museum, and the ABBA Museum. We might even see the changing of the guard at The Royal Palace in Stockholm and see other festivities on Sweden’s National Day, June 6th! Join the fun on this comprehensive and fabulous tour as we follow in the footsteps of Nordic royalty.

Join HPSO on a new adventure to some of southern France’s most extraordinary regions.

This special part of France has all of these things plus a countryside full of world-class vineyards, picturesque villages and chateaux, and a stunning coastline. Our two-week tour begins in the heart of Aquitane in the vibrant city of Bordeaux (one night) and ends near Marseille in Aix-en-provence (two nights). Along the way, we’ll stay four nights in the heart of Dordogne (in Sarlat), then two nights each in Toulouse, Montpellier and Fontvieille. Our tour includes visits to private and public gardens, the Lascaux caves, troglodyte cliff-dwellings, chateaux, medieval towns (including Carcassonne), wineries, and afternoon cruises on the Dordogne river and the Mediterranean’s La Calanques on the southern coast!
