RECAP

Over the past few weeks, we’ve shared the stories behind the five remarkable additions to the National Bonsai & Penjing Museum’s collections. These gifts, from visionary bonsai artists and collectors, reflect the vibrant evolution of this traditional art and its expanding scope in North America.

Blue Spruce by Karen Harkaway.

Thanks to the generous donors, these bonsai and suiseki continue as a living legacy — one that will inspire, educate, and connect people through the power of natural art.

Douglas Fir collected by Richard Le and cultivated by Bjorn Bjorholm.

These pieces are far more than beautiful additions to the Museum’s renowned Japanese, Chinese, and North American collections. They represent an evolution that honors tradition while propelling the art of bonsai forward.

Crepe Myrtle by McNeal McDonnell, styled by Bjorn Bjorholm.

Each tree tells a story of American creativity rooted in carefully selected native species. The Douglas Fir, Blue Spruce, Crepe Myrtle, and Western Hemlock are not only emblematic of North America’s diverse landscapes, but also demonstrate how bonsai in this region is developing its own voice—one that values innovation while continuing to pay homage to its rich history.

The suiseki offers a moment of peaceful contemplation, presenting evocative symbolism of the earth and its waterways that reminds us of our deep connection to the natural world. It also stands as a symbol of connection, friendship, and the enduring bonds between cultures that have preserved and shared this art form across generations.

In 2024, the National Bonsai & Penjing Museum welcomed five remarkable new additions—four exquisite bonsai and a striking suiseki. Each piece tells a unique story, reflecting the artistry, history, and evolving traditions of bonsai. Carefully selected for their cultural significance and artistic merit, these new acquisitions highlight the diversity of bonsai and its growing influence in North America. Join us as we explore the fascinating origins, creative vision, and horticultural mastery behind these latest treasures.

If you work in bonsai, chances are you’ve come across a blue spruce. Picea pungens is one of the most common of the 35 species in the Pinaceae family, originating in North America, Northern Europe, and Asia. Hard to miss – but have you ever seen one like this?

In early 2024, Karen Harkaway, a former board member of the National Bonsai Foundation and president of the American Bonsai Society, donated a beautiful blue spruce to the National Bonsai & Penjing Museum.

Blue Spruce (Picea pungens), 2024.

President’s Award 2024, Mid-Atlantic Bonsai Societies.

Her captivating conifer previously appeared at the 2022 and 2024 Mid-Atlantic Bonsai Societies' Spring Festivals and the U.S. National Bonsai Exhibition in 2023, where it won the North American Award for Finest Native American Bonsai.

In its natural habitat, a blue spruce can grow up to 200 feet, enduring heavy snowfall that forces it to form dark, flakey rough bark – one of its best bonsai attributes. For a bonsai display, that protective covering provides a lovely contrast with the spruce’s vibrant green needles and potential for beautiful deadwood features.

Todd Schlafer, of Denver-based First Branch Bonsai, first collected the specimen in 2016. Two years later, Harkaway purchased the tree from Schlafer’s vendor booth at the 2018 U.S. National Bonsai Exhibition. 

Harkaway’s spruce then underwent two stylings in 2019 and 2022 with Italian bonsai master Mauro Stemberger. Stemberger published videos on both the original styling and restyling, where you can learn about the importance of shade and moist, acidic soil for the spruce, as well as the duo’s styling choices.

Harkaway explains that the blue spruce had lived in a growing box and sought to regain health in her greenhouse, before its 2021 repotting with bonsai artist and former NBF board member Chase Rosade. The current moon-style container may appear as stoneware, but is actually European artist Erik Krizovensky’s cement creation – custom made to Harkaway’s specifications.

This tree is on display in the North American Pavilion at the Museum during your next visit. Don’t miss this incredible example of American artistry using a native species with a unique flair.

In 2024, the National Bonsai & Penjing Museum welcomed five remarkable new additions—four exquisite bonsai and a striking suiseki. Each piece tells a unique story, reflecting the artistry, history, and evolving traditions of bonsai. Carefully selected for their cultural significance and artistic merit, these new acquisitions highlight the diversity of bonsai and its growing influence in North America. Join us as we explore the fascinating origins, creative vision, and horticultural mastery behind these latest treasures.

In 2016, in the nooks and crannies of the Rocky Mountains in the greater Denver area, Richard Le discovered “Little Lonely Doug”.

Little Lonely Doug, 2024.

The tree – unique in its scale, taper, age, and character – represents one of North America’s oldest and largest conifers, the Douglas fir (Pseudotsuga menziesii). It was named in honor of Vancouver’s iconic, 230-foot “Big Lonely Doug,” the last Douglas fir standing in the Gordon River Valley, after intense and devastating logging deforestation.

Le, who spends time hunting for large yamadori, or “bonsai from the wild”, sells the trees he collects for use as bonsai or ornamental landscape trees. Little Lonely Doug, which was one of Le’s most compelling discoveries, ended up at Eisei-en, the well-known bonsai artist Bjorn Bjorholm’s nursery, garden, and school in Nashville.

Little Lonely Doug was the first tree to arrive at Bjorholm’s nursery upon its opening in 2018. There, the Eisei-en team repotted the fir in a more suitable container. In the spring of 2020, the tree went through another repotting and styling, while it finished out its term as a centerpiece at Eisei-en.

The fir was one of the last trees to leave the nursery when Bjorholm moved his business to Kyoto, Japan, where as a student he had completed a study abroad program and met his future wife. He also spent 16 years as a bonsai apprentice in Osaka. Marianne Duhamel, Montreal Botanical Garden’s penjing curator, rewired and styled the tree again under Bjorholm’s direction, just before its arrival at the National Bonsai & Penjing Museum. In March 2024, Le and Bjorholm donated this striking specimen to the Museum.

Staff from the U.S. National Arboretum, including Director Dr. Richard Olsen, Museum Curator Michael James, and Assistant Curator Andy Bello, were on hand to welcome the bonsai to the collections. They were joined by NBF board members Stephen Voss and Ross Campbell, as well as Executive Director Bobbie Alexander.

Also joining the welcome committee were Aaron Stratten, immediate past President of Potomac Bonsai Association, and Roberto Coquis, President of the Northern Virginia Bonsai Society. Our local clubs do so much to support the art of bonsai, and we are grateful for their presence. Everett Miller, the Diplomatic Associate for the Economic Section of the Embassy of Japan, attended the ceremony as well. We greatly appreciate their partnership and friendship.

These esteemed guests helped Little Lonely Doug find its home in the North American Pavilion, where it proudly represents an American species of evergreen conifer with a rugged appearance, hardy resilience, and uniquely “wild” look.

Little Lonely Doug also found a spotlight as the star of the National Bonsai Foundation’s limited edition World Bonsai Day 2024 clothing line, designed by Aaron Stratten.

The Museum is open daily (see hours), if you want to help Doug feel a little less lonely!

Introducing Stunning Recent Additions of Bonsai and Suiseki

In 2024, curators at the National Bonsai & Penjing Museum were thrilled to welcome four extraordinary bonsai from influential artists along with a striking suiseki, or viewing stone. In the coming weeks, we’ll share a lot more photos and the fascinating stories behind each one!

These additions bring fresh beauty and new depth to the Museum’s already remarkable collections, inspiring joy and wonder for visitors.

Last year’s donations include (click images to enlarge):

A striking Douglas Fir, collected by Richard Le and cultivated by Bjorn Bjorholm;

An intricate Crepe Myrtle from McNeal McDonnell, styled by Bjorn Bjorholm;

And a remarkable waterstone suiseki presented by Seiji Morimae on behalf of the family of Ronald Maggio.

The Museum is home to three historically significant bonsai collections—Japanese, Chinese, and North American—preserving them for public education and appreciation. While maintaining these living works of art, curators also seek new acquisitions that reflect the intricate evolution of bonsai. These new pieces enrich the story of the art form, showcasing its diversity, legacy, and evolving global influences.

Last year, curators focused on contributions from North American artists and collectors, highlighting the role of American art and representation of American culture within this ancient art form, which traditionally was shaped by Chinese, Korean, and Japanese artists. This enhances the narrative of bonsai as both an artistic and horticultural tradition rooted deeply in nature. But these are not just any bonsai.

Adding any specimen to the Museum’s collection is a meticulous and intentional process. Curators do not accept trees on a whim; each must hold historical and artistic significance, reflecting how cultures have transformed nature into art across generations. They carefully evaluate every bonsai and viewing stone based on its aesthetic qualities, artistic interpretation, and place in the broader story of bonsai. Whether naturalistic, highly stylized, or a unique blend of both, each new addition contributes to the ongoing evolution of this art form.

Last year’s acquisitions specifically highlight the role of American artists in shaping bonsai’s future. These trees embrace native species rather than adhering strictly to traditional selections, demonstrating both innovation and an American sensibility within this deeply rooted East Asian tradition. Each piece brings a distinctive vision, skillfully showcases the unique beauty of North American flora, and adds a chapter to the ever-growing legacy of this living art form.

The National Bonsai Foundation is proud to help introduce these five remarkable specimens into the permanent collection at the National Bonsai & Penjing Museum. We extend our deepest gratitude to the artists and generous donors who made these gifts possible: Karen Harkaway, Richard Le, Bjorn Bjorholm, McNeal McDonnell, Nick Lenz, Mike McCallion, the family of Ronald Maggio, and Seiji Morimae.

Remembering Barbara Hall Marshall

The National Bonsai Foundation (NBF) is saddened to announce the passing of one of its most steadfast supporters, Barbara Hall Marshall. Mrs. Marshall died April 21, 2021, in Kansas City, Mo., at age 97.

A lifelong philanthropist, Mrs. Marshall had a keen interest in the small and precise that led her to grow bonsai and become a founding member of the Bonsai Society of Greater Kansas City. She later joined NBF and served on the NBF Board of Directors for many years, eventually being appointed Honorary Director in 1998. 

Mrs. Marshall was a most generous benefactor to NBF and the National Bonsai & Penjang Museum at the U.S. National Arboretum. Donations from Mrs. Marshall provided critical marketing, administrative and programmatic support to NBF over the years, including an internship program, an assistant curator position and the establishment of the John Y. Naka North American Pavilion.

“Barbara’s dedication to bonsai and NBF was truly second to none,” said James Hughes, Chair of the Board of Directors. “Her presence is deeply felt throughout NBF and the Museum, and we would not have reached such great prominence nationally and internationally without her support. It has been an honor and a privilege to have her as an important member of the bonsai community.”

Mrs. Marshall’s love of art and the people who create it formed the basis for her lifetime of supporting arts education. She became a nationally recognized collector of miniatures and in 1982 co-founded the National Museum of Toys and Miniatures, where her personal collection remains on permanent exhibit. She was involved with many other organizations in and around her hometown, including the Kansas City Art Institute, Kansas City Symphony, the Nelson-Atkins Museum of Art and The Land Institute in Salina, Kansas, where she led efforts to construct a research facility in 2018.

The second child of renowned Hallmark Cards founder J.C. Hall and his wife Elizabeth, Mrs. Marshall was involved in the Hallmark Company for more than 50 years. She was a member of the company’s product review committee and later became part of a group charged with making acquisitions for Hallmark’s renowned art collection.

According to her official obituary, Mrs. Marshall attended Bradford Junior College and graduated from the University of Kansas in 1945. She was predeceased by her husband, Robert A. Marshall, and is survived by three daughters, two grandchildren and one great-grandchild, among other family members. 

Like many bonsai and penjing enthusiasts, Mrs. Marshall was fascinated by the grand stories we can capture in miniature form — whether through a fine-scale dollhouse or a small tree in a pot. We will always be in awe of Mrs. Marshall’s dedication to the arts and deeply proud that she chose to share her generosity with NBF. Her influence and passion for bonsai will live on through NBF’s mission and the beautiful trees in the Museum’s national collection.
