I am not sure what kind of wood it is. You can contact the owner and she might be able to tell you. Thanks for looking!

Lucy, I'd love to get the name of whomever did Melissa's fence, design, and contracting.

I agree, I would love to see who arranged this work of art! I'm going to be remodeling in a little bit and I am searching for ideas. So far, this is my favorite yard that I've seen! Have you though about putting some vines and plants in the roof of your patio cover? http://www.outdoorfence.com/residential-fencing-wood/
