There is no substitute for being there. If you search the web for information on how people use plants at home in Japan, you will find a ton of pages talking about historical styles, how the rich build their private gardens, and which Japanese plants you can buy for your own home. In truth, most people in Japan have tiny homes, and not much space to build huge gardens. But plants are very much part of their lives. So every little house in a city will have a small space with plants. On a gloomy day, as we walked from the famous Golden Pavilion of Kyoto to the equally famous gardens of the Ryoan-ji, we kept stopping at every second doorstep. In a tiny space, sometimes only the width of a step from the street to the door, every house had a plant or two. One of them was this cascade of yellow flowers which I could not recognize. The narrow focus of my macro lens gives lovely photos, but may not be ideal when you want to identify a plant from its photo. Can it be some kind of an anemone? Is anyone from a temperate region of the world ready with an identification?
As I took the featured photo, The Family found the larger garden whose entirety you see in her photo above. I can recognize asters. But the rest are outside my experience. The pot in the foreground is a whole Japanese garden in itself: at least three plants, arranged tastefully to show colours at different times, but green most of the time. Of the three, one stands tall, one droops and the one with the springtime colour spreads. Such meticulous planning! Each piece can occupy your attention, and that is the purpose of gardens after all.
