I saw these palms inside a marbled atrium in downtown San Francisco. I don’t think a haircut will solve the issue of vertical growth overtime so I wonder what happens when they reach the top.
Meanwhile in the Mission District, these tall palm trees align busy sidewalks. If you happen to encounter these trees on a windy day, you might find some of them swinging in an unsettling manner.

I like how it looks like the reflected palms are descending the staircase.
I like how the windows of different neighborhoods reveal different images.
