I started this blog somewhere over Japan, or maybe it was in a hotel room in Kyoto at midnight, trying to get the day’s impressions down before sleep erased them. What I found, and what keeps me coming back to write, is that documenting these visits does something the visits themselves don’t — it’s a kind of double processing. First you experience the tree, the artist, the moment. Then you sit with it again on the page, and only then does it really settle into you.

I have a few weeks now before my next trip, so before I get swept up in whatever comes next, I want to go back to April — back to California. It doesn’t feel recent. So much has happened since, Japan most of all, that April already feels like a different chapter of the year. But it deserves its place here, so let’s rewind.

Two Conferences, Two Weekends

April had me in California for work — RSA Conference in San Francisco, followed a week later by a Palo Alto Networks event in LA. Two cities, two purposes, and in between them, two free weekends.

San Francisco is not new territory for me. I spent fifteen years working for RSA before joining Palo Alto Networks, so I’ve lost count of how many times I’ve landed at SFO. I’ve always loved this city — the fog, the hills, the energy of it — and every visit over the years I tried to see a different side: the city itself, the Bay, the wine country in Napa, even Highway 1 running south along the coast. What I never knew, all those years, was that the Bay Area is quietly one of the great bonsai capitals of the world outside Japan. Some of the finest bonsai artists and collections anywhere are sitting right there, a short drive from conference hotels I’d stayed in a dozen times without a clue.

And then I met Jonas!!!

This is where I have to thank my teacher, Shai. I mentioned to him I’d have a free weekend in the Bay Area, and within days he’d put me in touch with Jonas Dupuich.

If you’re in the bonsai world, you know the name. Jonas is the person behind Bonsai Tonight, one of the most respected bonsai blogs and teaching resources anywhere, author of The Little Book of Bonsai, and co-founder of the Pacific Bonsai Expo, the biannual show that alternates between the east and west coasts of the US. He’s also, everyone will tell you, simply one of the kindest people in the community — patient, generous, completely without ego about a body of knowledge built over decades. I understood why within about five minutes of meeting him. He wrote back to my message almost immediately and invited me straight to his home to see his collection.

I won’t share the location, and I won’t share photographs of the garden itself. Trees like the ones Jonas has spent decades developing are, put simply, worth a great deal, and where they live is something the community protects carefully. But trust me when I say: it was extraordinary.

We spent a few hours together in his workshop, and at some point he let me put my hands on some of his best trees — trees I recognized instantly from books and films, trees I never imagined I’d touch, let alone work on. My hands were actually shaking. I’m still such a beginner in the arc of this practice, and here he was letting me near material that represented years, sometimes decades, of someone else’s patience. That kind of trust from a master is its own kind of teaching.

While we worked on a couple of pines, we talked — about his path into bonsai, what a full-time life in this art actually looks like, and about the Pacific Bonsai Expo, which he co-founded and helps run. I need to make it a point to attend one day, wherever it lands next.

Lake Merritt, in the Afternoon

Jonas sent me, for the second half of the day, to the Bonsai Garden at Lake Merritt in Oakland — and I’m glad he did. It’s the only major all-volunteer bonsai garden in the country, built and maintained entirely by volunteers from across the Bay Area. It was first conceived in the late 1970s by horticulturalists Toichi Domoto and Bill Hashimoto, and finally opened in 1999. The collection includes some genuinely historic trees — among them a Daimyo Oak said to have been presented by the Japanese government in 1863, during Lincoln’s presidency, and a pine that was exhibited at the 1915 Panama-Pacific International Exposition in San Francisco. The garden has a sister collection in Southern California at the Huntington, both part of the Golden State Bonsai Federation.

What stayed with me most, though, wasn’t any single tree — it was the volunteers. Watching them work quietly on the collection, some clearly still learning themselves, absorbing technique from more experienced hands nearby.

There’s something very grounding about a museum-quality collection that exists purely because a community decided to show up for it, week after week, for free. I walked through slowly, taking it in, trying to watch the way the volunteer-artists watched the trees.

One Last Stop: Eric Schrader’s Cork Bark Elm

Before I flew back out that week, Jonas connected me with one more person — Eric Schrader, who runs Bonsaify and is well known in the community for his work and writing on bonsai design. Eric had a few trees I was especially curious about, and one in particular stopped me: a cork bark elm.

We grow plenty of elms in Israel — they do beautifully in our climate — but I’d never spent real time with the cork bark variety in person. The bark itself is almost sculptural, deeply ridged and textured in a way that gives the whole tree a sense of real age, even on younger material. It’s one of those details that photographs never quite do justice to; you have to run a finger along it to understand what makes it special.

That was the California chapter — or at least the first half of it. The next post picks up a week later, in Los Angeles, with a visit to the Huntington Gardens.
