Not where I live near San Diego, it's not.
Out here the foliage pretty much looks like this if the plants are not constantly irrigated. We are experts in shades of brown and gray. And dry.
If you feel like asking,
How many greens are there?
and doing some first-hand research, you should go to a place where they are experts on that color. England. Or Sweden. Or some jungle-like place. Not the desert.
The word green is derived from an ancient word for grow.
Wikipedia shows some sample greens here:
Green is a color reflected off some surfaces that has a wavelength of about 520-570 nanometers. As the waves get longer, the color shifts towards Yellow. Orange and Red are longer. Blue's wavelength is even shorter than green. But I digress.
Because plants produce green through photosynthesis and the process requires both sunshine and water, you're better off looking for greens in a wet climate.
The green-covered road is England.
The orange butterfly is on a Swedish bush.
The vine-laden fence is in Italy.
The ripening grapes are in Greece.
I haven't been to Ireland, but it's known for being green.
Many countries have green in their flags - most of them are either very green themselves (Ireland and Brazil) or they are Islamic countries because the color is considered sacred.
Could the respect and reverence for the color green be related to the idea of the oasis, or the Garden of Eden? The desert world which is the center of Islamic development is dry as a bone, just like Southern California.
This is our kind of green.
