Honestly speaking, I've never really liked the color green. I have never own anything green, except for my backback. It's "camouflage"-type of green mixed with grey elements.

However, during the summer for instance, I often take photos outside of flowers, buildings and whatever I can think of, and I just need to have some green colors in those photos. They become so much better with a bunch of green stuff mixed with everything else. Much like your photos.

The contrast between green and red, like in your first photo is really amazing. My favorites are either the first or last one. Both are amazing.
