Summer 2020 is officially the summer of the bonsai blog series! We’re launching another string of blogs to highlight the fascinating history and teachings of some of the most influential bonsai masters. For our first edition, we spoke with Bill Valavanis, a National Bonsai Foundation director and bonsai artist, about his time training under Yuji Yoshimura.

Valavanis dubs Yoshimura his “Japanese father” from whom he learned on the weekends while studying horticulture during college in the 1960s. He said Yoshimura felt like a god to him when they first met, as Yoshimura’s book The Japanese Art of Miniature Trees and Landscapes – later reprinted as The Art of Bonsai: Creation, Care and Enjoyment – is considered a “bonsai bible.” The book is the first authoritative source for bonsai artists written in English.

Yoshimura began his bonsai work under his father’s tutelage. He and Alfred Koehn, a notable authority on Japanese art, organized and produced the first beginner’s bonsai course at Yoshimura’s family nursery in Tokyo in 1952.

Yoshimura’s father, who rekindled the craft of classical bonsai, was the most influential person in his bonsai career. Valavanis said Yoshimura’s family remained anchored in Japan, but he wanted to spread the art of bonsai around the world. He traveled to Australia, Hong Kong, England and across the United States, where he and his family lived for many years.

But Yoshimura sacrificed the stability of his relationships when he left home. One of his younger brothers took over his garden after he left, Yoshimura’s wife and one daughter eventually moved back to Tokyo and Yuji was highly criticized in Japan for teaching the “Yanks” in America – but Yoshimura loved the United States. 

“He found Americans very friendly,” he said. “He went through a lot of students but he would take care of them, tell them extra things, treat them nicely and encourage them.”

Yoshimura took Valavanis to Japan to meet other influential bonsai figures. Upon returning to the United States, Valavanis lived with him for almost a year to study the classical Japanese style of bonsai. He said Yoshimura would personally demonstrate wiring or care techniques, unlike many current apprentices learning bonsai in Japan, who are often left to grasp concepts by themselves. 

“He taught me the basics and introduced me to the Japanese fine quality classic bonsai,” Valavanis said. “He showed me where I can improve, get more information and how to study.”

Yoshimura relied on old, historic books – some of which he took from his father in Japan – for bonsai knowledge and left Valavanis his library when he retired. He is known for his strict teaching style, adhering to traditional Japanese designs – his father’s influence – and curt lessons. 

“Once when I was cleaning the kitchen floor, I put back our two chairs and went out to do something, but my chair was missing when I came back,” Valavanis said. “I put it back two or three times, but finally I got the hint time for me to leave.”

Even after the two parted as roommates, Yoshimura routinely visited Valavanis’ garden, helped him establish a bonsai magazine and remained a teacher and friend until he died in 1997. 

Valavanis said the most important takeaway from Yoshimura’s teachings is to do what he thinks is right and avoid too much influence from other artists. He took that advice with him to start the first American bonsai exhibition, the highest level show in the United States, which is now in its seventh year. 

“He told me to stand on his head or shoulders to take the art higher,” Valavanis said. “He wanted me to use what he had and go improve.”

NBF Taps Sophia Osorio for 2020 First Curator’s Apprentice

Screenshot 2020-03-20 at 3.40.09 PM.png

We are pleased to announce the hiring of the NBF 2020 First Curator’s Apprentice, Sophia Osorio. 

Robert Drechsler served as the first curator for the National Bonsai & Penjing Museum from 1976 to 1998. During the celebration of the 35th anniversary of the Museum in 2011, NBF established an internship – called the First Curator’s Apprenticeship – to honor Robert’s many years of service. The apprenticeship aims to train the next generation of American bonsai artists.

Sophia, who started on March 10, said a previous internship at the Central Park Conservancy in New York City first piqued her interest in wanting to work outside.

“I’ve known since graduating college that I never wanted an office job,” she said. “I wanted to be outdoors doing hands-on work.”

Sophia, 23, said her passion for trees first came to light during an environmental ethics course she took during her undergraduate education at Binghamton University in New York. She learned about the philosophical side of the environment, like how society’s carbon footprint affects Earth. 

“It sort of inspired me to want to make a difference in my own small way,” Sophia said.

She said she first became interested in bonsai during an arbor culture certificate program she took part in at the New York Botanic Garden in the Bronx. Sophia said she saw the posting for the apprenticeship at the garden and decided to apply. 

“I’m still trying to find a specific career path, like what I would like to do specifically with trees, because I feel like the options can be endless,” she said. “Bonsai have a visual aesthetic to them. I thought that was super interesting to learn more about, like pruning and care and things like that.”

Sophia said she has spent her first week working closely with Museum Curator Michael James, jotting down notes and tips about the trees she will be working with for the next year. 

“There’s so much care and many different tactics that go into keeping trees alive for so long, like the Yamaki Pine,” she said. “Some people can’t even keep houseplants alive, so I think that’s amazing and it’s definitely a skill I would like to pick up on.”

When she isn’t learning about the Museum’s collections, Sophia keeps active with trips to the gym, hikes and long walks. She recently visited the Redwood Forest in California. 

“You can leave me in a national park for hours and I'd be fine,” Sophia said. “I'm down for anything outdoors.”

We look forward to all Sophia will contribute to the Museum in her capacity as First Curator’s Apprentice. A special thanks to our 2019 apprentice Andy Bello, whom the U.S. National Arboretum has hired as a temporary agricultural research science technician.

The National Bonsai Foundation is looking for a new funding source for this program. Please contact us if you are interested.

The National Bonsai Foundation is sad to announce the passing of former Board of Directors member Jack Wells. 

Wells was an establishing member of NBF in 1982, served on the Board for many years and previously held the top post at the Potomac Bonsai Society. 

“Jack’s dedication to and history of the Museum was evident from the start,” NBF Co-Presidents Felix Laughlin and Jack Sustic said in a letter to NBF board members. “As a friend, mentor to many and bonsai leader, Jack played a significant role in the development and appreciation of the art of bonsai in our nation’s capital.”

Born in Independence, Oregon in 1925, Jack grew up on the family farm which eventually became a century farm. He graduated from Oregon State University in 1951 from the College of Agricultural Sciences with a major in horticulture, according to his obituary.

Through the International Foreign Youth Exchange program, Wells traveled to Bolivia where he discovered his love for agriculture. While working with the USDA as an Agriculture Marketing and Seed Specialist, Wells traveled to 68 different countries to educate on agriculture improvement techniques. He also worked for the American Seed Trade Association, according to his obituary.

He is survived by his wife Kathi, four children, two stepchildren and 16 grandchildren, his obituary states.

A GUIDE TO BONSAI: Forest Bonsai Presentation

Creating Forest Bonsai: A Relatively Easy & Inexpensive Way to a Lifetime of Bonsai Enjoyment

Our Co-President, Felix Laughlin, gave this presentation on November 10, 2019 at the Blue Ridge Bonsai Society in Asheville, NC, as part of their regular education program for club members. We wanted to share it with you.

Laughlin created this presentation in order to do two things:

1.) To show how easy and relatively quick it is to create a forest bonsai using young seedlings.

2.) To raise awareness around the late Saburo Kato, a Japanese bonsai master who made possible the 1976 Bicentennial bonsai gift that lead to the birth of the National Bonsai & Penjing Museum. Throughout the presentation, Laughlin cites Kato’s classic book on forest bonsai plantings, Forest, Rock Planting & Ezo Spruce (Translated into English and published by NBF - Available for purchase here).

The seedlings Laughlin used were Stewartia seedlings grown and donated for the demonstration by Sage Smith. As you will see from the photographs, his fellow club members were a big help with every stage of the process, from preparing the young trees to tying them down in their proper place in the container.

Enjoy!

As of February 1st, 2020, Johann Klodzen will step down from her role as Executive Director of The National Bonsai Foundation (“NBF”). All of NBF’s officers and members of its Board of Directors are sincerely grateful to Johann for her nearly 20 years of service guiding NBF’s work in support of the National Bonsai & Penjing Museum at the U.S. National Arboretum (the “USNA”).

During her tenure at NBF, Johann collaborated closely with several Directors of the USNA, most recently Dr. Richard Olsen; supervised NBF’s involvement in numerous projects at the Museum, including the complete rebuilding of The Japanese Pavilion and most recently the development of a master plan for the future renovation of the rest of the Museum; oversaw NBF’s efforts to give NBF and the Museum a significant online presence; oversaw the inauguration and publication of NBF’s Annual Report in 2016, which received several awards for design; and worked tirelessly to give the Museum an increased recognition in the United States and across the world of bonsai enthusiasts. Her passion for and knowledge of the artform was infectious to all of those who had the privilege to work alongside her. Though she is leaving the position, we know Johann will continue to be a part of our bonsai family.

While we conduct a search for a new Executive Director, we are delighted to announce that Bobbie Alexander will step into the role as Interim Director of Administration. Bobbie has served as Chief of Staff and Managing Director of Governance for the American Diabetes Association, as a Senior Administrative Consultant for The Food Allergy Research & Education Association and most recently as Chief of Staff and Operations for the National Health Council. We are confident that during this transition period, we are in very good hands.

Though we begin 2020 on a note of bidding farewell to our esteemed colleague, there is much to look forward to in the new decade ahead. Our next Executive Director will be tasked with the exciting planned renovations of the Museum, overseeing NBF’s efforts to make that project a reality, thereby ensuring the continuation of NBF’s mission of preserving a history, protecting a legacy, and preparing a future.

Photographing Bonsai with Stephen Voss: A Winter’s Visit

As a photographer who now makes a living snapping pictures of some of the world’s most influential figures, Stephen Voss didn’t always know that photography could be more than a hobby.  Once a bonsai novice, he certainly didn’t think he would publish a photography book of bonsai.

Now that he’s an accomplished photographer, Voss wants to share his “tricks of the bonsai photography trade.” This entry is part of his regular guest blog series, “Photographing Bonsai with Stephen Voss"," published on NBF’s blog, covering everything from lighting, angles and mindset needed when photographing the trees.

Washington, D.C. has resisted giving itself over to winter this year, with 70 degree days and only a handful of nights below freezing. On one of these warm January days, I visited the National Bonsai & Penjing Museum to photograph the trees in the winter light.

While the trees are the main attraction, the Museum grounds are not to be overlooked. The cryptomeria-lined entrance gives you the sense of moving from one world to another, emerging through the main gates to the courtyard where a single tree can be seen.

To find the majority of the trees, you must walk through the Chinese Pavilion, in which the trees spend the colder months. The open air building boasts a roof of translucent glass, which keeps the pavilion a few degrees warmer than outside. But more importantly, this glass is the key to creating some of the most beautiful light the Museum sees all year. The low-angled winter sunbeams scatter and soften as they pass through the panes but somehow still retain a certain crispness as they fall upon the resting trees.

The trees are often just inches apart from each other, allowing for one to observe the collection as a miniature bonsai forest – a remix of the typical presentation that gives each tree its own space. In these tight configurations, there are photographs to be made exploring the relationships between the trees.

There are signs of life to be found in the pavilion even a third of the way through winter. Camellias are bursting with blooms and the Chinese quince’s jewel-like green buds erupt skyward. Winter light in the Chinese Pavilion never comes from straight above, but shines from hard angles, reflecting the shortened daylight hours.

The Toringo Crab Apple, in training since 1905 and one of my favorite trees, still bears some small yellow fruit that faintly sways in the breeze from the circulating fan.

Winter is a season of rest and stillness, and I don’t think there’s a better time of year to visit the Museum. Over the year and a half that I was photographing my book – In Training, A Book of Bonsai Photos – the majority of the photographs were produced from the two winters I spent there. The bare deciduous trees become abstract forms, and it’s at these times that the invisible hands of the bonsai master’s work are most clearly seen. 

Hiring: First Curator's Apprentice

The first Curator of the National Bonsai & Penjing Museum was Robert Drechsler who served in that position from the founding of the Museum in 1976 until 1998.  In 2011, during the celebration of the 35th anniversary of the Museum, an internship for the Museum was established by the National Bonsai Foundation to honor Mr. Drechsler for his many years of service. It was called the First Curator’s Apprenticeship.

The purpose of the apprenticeship is to educate and train a new generation of American bonsai artists. It is sponsored by Toyota North America and the Hill Foundation.

Applications are currently being accepted for the 2020 First Curator’s Apprentice.

Photographing Bonsai with Stephen Voss: A How To

When I began photographing the trees at The National Bonsai & Penjing Museum, I knew little of bonsai and had even less of an idea of how to take pictures of the miniature wonders. What I did know was that, if I wanted to have any success at this, it would be by creating something new, apart from the tree itself. 

Making a photograph to record what something looks like is a perfectly reasonable goal, but it only scratches the surface of the expressive possibilities of photography. But where do you start? Here is an exercise to partake in if you’re just getting your feet wet in the realm of bonsai photography:

Walk around the museum, being sure to look at all of the trees until one catches your eye. It’s not a bad thing if that tree happens to be in good light (open shade for instance, not bright sunshine).

Stand in front of that tree, set a timer on your phone for ten minutes, and do nothing. By nothing, I mean just look at the tree. Bend down, look from the side, just don’t stop looking at it. Notice the way light hits different parts of it, think of the generations of people who have worked on this tree and try to find something new about the tree that you’ve never seen before.

After 10 minutes, take 15 shots of the tree, each one different than the last, like so:

At some point during this exercise, you may find yourself questioning the whole enterprise, feeling foolish or that you've simply run out of things to see. This feeling is part of the process. Without this doubt and uncertainty, without exhausting your sense of what’s there, you can’t really make progress. As someone who’s felt these unsettling, frustrating feelings many times in my photographic life, I urge you to just keep at it, keep looking, keep seeing.

Learning to see is a strangely undeveloped skill for many photographers and developing it requires time and patience. But why bother? If you’re like me, with no discernible skill in working with bonsai, but a deep appreciation and love for the trees, looking closely is a form of appreciation, a way to connect. With a keen eye and a bit of luck, it can also be a way to turn that experience into a meaningful photograph.

Penjing Defined by Master Zhao Qingquan

If you’re not familiar with the nuances differentiating bonsai – which originated in China and has been popularized by the Japanese – from the Chinese art of penjing, the two forms probably seem very similar or even identical. But with a little background, you’ll see there are important differences that distinguish most penjing from bonsai. We spoke with renowned penjing master, Zhao Qingquan, to bring you this blog.


Screenshot 2019-10-07 at 2.35.34 PM.png

Zhao was born in Yangzhou City, China, where his father – a penjing enthusiast – first introduced him to the art of penjing. Other than his father, the most influential figure in Zhao’s life was his professor Xiaobai Xu, who bolstered his penjing knowledge.

“I am always proud of my final choice of the penjing as a career,” he says.

As Zhao explained in Penjing: Worlds of Wonderment: “In the Chinese language, we distinguish between three kinds of penjing, shumu penjing (tree penjing), shanshui penjing (which literally translates to “mountain and water penjing” but is usually called “landscape penjing” or “rock penjing”) and shuihan penjing (water-and-land penjing).

Screenshot 2019-10-07 at 2.36.10 PM.png

Zhao says that artists in China constantly innovate and develop penjing forms, so the style and content of the art form is becoming increasingly varied, but all have the “same essence of applying natural materials to express natural landscapes.”

Zhao explains that bonsai is actually the same as shumu penjing (tree penjing), one of the three categories of penjing. Tree penjing (bonsai) uses containers to display natural trees and plants, and artists will use wiring, pruning and chiseling techniques to create the composition’s dominant elements, he says.

Screenshot 2019-10-07 at 2.37.25 PM.png

In contrast, the second category of mountain and water penjing take the form of landscape scenes: artists will cut and reshape rocks to embody islands or mountains and often add small live plants to flesh out the scene, Zhao says. In the third category of water-and-land penjing, artists depict more “complete” scene, using materials like soil and water, as well as miniature figurines, he adds.

Zhao points out that “as an art aiming at ‘seeing the big from the tiny,’ penjing is often created as a method of self-expression to convey personal emotions.”

He reflects that humans naturally desire a tranquil life that immerses us in nature, but we often alienate ourselves from our natural environment to focus on work and family. Zhao says the pressure to survive in a modern and increasingly industrialized world facilitates humans’ tendencies to not prioritize connections with nature.


 “Penjing art allows us to pursue peacefulness and tranquility in our inner hearts and fulfill our desires of being part of nature,” he said. “Therefore, penjing as an old traditional art has been renewed.”

Screenshot 2019-10-07 at 2.38.18 PM.png

Penjing is a traditional Chinese art that can be traced back to as early as the Tang Dynasty (618-907 A.D.). Bonsai (tree penjing) was brought to Japan during the Southern Song Dynasty of China (1127–1279) or the late Heian Period in Japan (794–1192), Zhao says. 

Three nationwide penjing communities have been established successively in China: the Chinese Society of Landscape Architecture Flower Penjing Suiseki Association, the Chinese Penjing Artists Association, and the Penjing Branch of China Flower Association. 

“As an art form expressing the human desire to love nature and peace in the world, penjing has gained increasing popularity around the globe,” Zhao says. “Penjing is used to decorate our homes and to cultivate self-expression, helping us achieve a healthier and happier life.”
