Thank you all for the kind words. I'm never going to enter a photo contest so this is it, I guess.
The shape of the garden is almost exactly the shape of the banner, very long and not too tall. When I saw how grainy the cropped photo came out, I decided to illuminate the situation with individual photos.
It is my intention (most of the time) that these pictures tell a story, or record a history. Flower pictures tell you how these plants go looking for love. The bicolored aloe flowers are an excellent example of that. The hummingbirds see that change from red to yellow and know exactly where to zoom in for fresh food.
The reason that public garden is so long and narrow (and public) is that it occupies a center median between two parts of a road, one about 10 or 12 feet higher than the other. Most of the big old plants (like all the agaves along the top) get zero supplemental irrigation, meaning they they can easily survive our months-long summer drought every year.
