Green Striped Rock

Hi everyone first time posting here. I found this rock in my backyard of my new home. Caught my eye and I'm loving the colors and the whole rock. If anyone has ANY type of info I would love to know thanks everyone. Btw here's a picture of it.

The green could be caused by epidote or perhaps serpentine. I'm thinking the first; to test it - see if a knife will scratch it.
Epidote won't be scratched by a knife, serpentine however will.

looks like a rare form of rhyolite
