The Botanical Building at Balboa Park and a book review: The Conservatory, Gardens Under Glass

Our next stop at Balboa Park was The Botanical Building, aka the Lath House. This structure was originally built for the 1915-16 Exposition and is one of the largest lath houses in the world.  

The building just reopened (on December 6th), after being closed to the public for three years while Phase 1 of a $28.5 million revitalization project was completed. Included in the renovation was the restoration of stucco arches, a new redwood lath roof, improved irrigation systems and lighting, and access for people with disabilities (more info here).

The stunning view looking out from the front of the lath house...

And the view inside...

The structure is amazing.

Absolutely gorgeous.

The plants? Not so much. I mean they're fine, right up there with a nice mall. But interesting and inspiring? A good fit with their location? Not even close.

How absolutely disappointing.

I remember feeling awe when I walked thru back in 2014 (photos here).

This time, no. No awe. It looks like an underfunded bedding out scheme.

This corner was the most interesting. 

That stump was cool!

And there were pyrrosia, P. lingua 'Crested', but not even a few pyrrosia were enough to cheer me up.

The next phase of the renovation is supposed to involve the plantings around the outside of the building. Let's hope they do better there.

Moving on to a quick book review (so this post isn't completely disheartening) let's talk about The Conservatory, Gardens Under Glass, by Alan Stein and Nancy Virts, from Princeton Architectural Press (2020). It seems fitting since the Botanical Building is mentioned in the book, even though there's no glass.

I first learned of this book when Camille (aka tahomaflora) mentioned receiving it as a Christmas gift. I immediately looked it up, but since the price was rather steep for an impulse buy (over $50/$40 used) I decided to get it from my local library. Nope. It seems Portland’s lack of interest in conservatories runs even to the library system! (Tacoma, Seattle, Spokane, San Francisco all have conservatories, but not Portland). I was finally able to track it down via an Interlibrary loan, the book came to me from the Coos Bay Public Library.

Here's a tidbit from Chapter Five: New World Conservatories. They're writing about the late nineteenth century in the Unites States and Canada…

"The perception of North America as a backwater even extended to the continent’s flora and fauna: America’s native species were considered inferior to Europe’s. Thomas Jefferson (1743-1826) railed against the belief of French scientists that flora and fauna inevitably degenerated when transplanted to America. A famous eighteenth-century naturalist and the head of the Jardin des Plants in Paris, Georges-Louis Leclerc, Come de Buffon (1707-1788), wrote that in America, all things “shrink and diminish under a blackened sky and unprolific land.” In response, Jefferson dispatched twenty soldiers to New Hampshire to find a bull moose as proof of the “stature and majesty of American quadrupeds.” Buffon later penned a retraction, but the state of botany as a science in the colonies and early republic was also disparaged. Victoria Johnson, the author of American Eden (2018), relates that a French botanist, in Manhattan on a mission from Louis XVI, wrote home, “There are no informed people here, not even amateurs.”

Writing about Henry Phipps Jr. (1839-1930), the man behind Phipps Conservatory in Pittsburgh, Pennsylvania, the authors note that he. “…was genuinely concerned about the well-being of the working class and thought a public conservatory would benefit the city.” Of course that’s after they noted that the industry that fueled his fortune (steel) also “created a thick blanket of smog, that damaged the health of the workers.” Once completed the Phipps Conservatory and Botanical Gardens was donated to the city of Pittsburgh “on the condition that it be open on Sundays so that laborers could go there on their rest day.” Hmmm. Making my fortune I damaged the natural world, but now I am giving back. 

Phipps Conservatory is definitely one I would like to visit, someday. The Scripps Conservatory in Detroit also looks like a great place to see...

I count myself rather lucky to have visited several of the buildings on their list of New World Conservatories...

I've been to the Conservatory of Flowers, The New York Botanical Garden, The Fernery at Morris Arboretum, Volunteer Park Conservatory, Longwood Gardens, The Balboa Botanical Building, United States Botanic Garden, and Allan Gardens Conservatory.

I thought this was an interesting tidbit in the section on the Volunteer Park Conservatory in Seattle: "From the beginning, according to the conservancy’s website, “the Conservatory’s mission was to educate, collect, and conserve threatened plants and to transport visitors beyond the open green spaces of the Park to another world that examines connected environments and plant species from around the globe.” Thus, the conservatory is no longer only a place to study botany, or explore the economic potential of plants, or even find a green respite for urban populations. It now has a conservation mission."

I've also had the privilege to visit some of the Modern Glasshouse Marvels...

I've seen the Jardin des Plants, Princess of Wales Conservatory, Parc André Citroën, The Davies Alpine House and of course the Amazon Spheres. Not on either of those lists are the conservatories at Kew (which I've also been lucky enough to visit), and that's because they are the subject of much discussion earlier in the book.

Here's where I admit that I didn't read every word in this magnificent book, it had far too many details (painstakingly researched I'm sure) on the early days. I skimmed, I read the interesting bits, I soaked up all the lovely photos. I then returned it and felt lucky to have been able to put in a request and have the library system track down and deliver (to my nearest library) the book. Let's hope this benefit doesn't disappear under the current administration, along with so many others.

Kate O. Sessions Cactus Garden and Palm Canyon, at Balboa Park

In Monday's post I referenced the Balboa Park Club building, and shared a view of it from the side. Here's the front of the building and the plants...

For a minute I thought it looked like the Dasylirion quadrangulatum (guessing?) was gonna bloom, but I think that's just congested new growth.

I wonder if that pachypodium was set free from growing in a container like those I wrote about in my last post?

Behold, the Kate O. Sessions Cactus Garden...

I swear when we visited back in 2014 this was called simply the Old Cactus Garden (as opposed to the Desert Garden which is in an entirely different area), but now it's named after it's original champion: "This historic garden was developed under the direction of Kate Sessions for the 1935 California Pacific International Exposition." (source)

Oh that banksia!

I wish I knew enough about banksia to give you a proper ID, but I do not. An online search said maybe Banksia ashbyi?

It's pretty wonderful whatever it is.

I think it's all sorts of fabulous when a blooming agave can be left in place to gracefully decline. 

There are lil pups hiding under the dying skirt.

Dry, dry, dry...

Somehow this opuntia still managed to bloom and set fruit, even though the pads themselves are shrunk and paper thin.

A healthier speciman.

That patch of agave... *swoon*...

What is it? I don't know. I want to call it Agave filifera, but it seems that name has been taken over by a thin leaved plant.

My bad. I lined up the dried agave bloom spike so it looks like the tree behind it is part of the structure.

Our trip was timed so it seemed most of the aloes in San Diego were blooming while we were there. Sadly I know very little about aloes, other than how to appreciate them.

It would have been rather alarming to be standing there when that large bit of palm blew down.

I wish opuntia grew woody trunks up here in Oregon.

We've walked on now and are heading through the Palm Canyon.

 

I do love Caryota obtusa (fishtail palm), although I learned that Andrew does not. Crazy man!

Washingtonia robusta, aka Mexican fan palm I believe?

Phoenix dactylifera? (date palm)

I'm palm stupid, so my ID's are guesses only.

This was an odd business at the base of one of the Washingtonia robusta (?). It almost seemed like there was another plant growing on it at some point, and part of its root mass was left behind.

Speaking of plants growing on plants, walking out of the canyon I looked down to see this...
