I live outside of Denver, and I find this concept to be extremely exciting at an architectural level. That being said, it will be interesting to see how well the greenery in the "crack" will hold up to the extremely dry climate, as well as the extreme temperature swings in the area. I'm assuming they will use native species, which are amazingly hardy. Ponderosa pines and other tree species (Colorado Blue Spruce, etc) are known world-wide in the bonsai community for their extreme hardiness. I can drive 5 minutes west from my house and find excellent yamadori without walking more than 5 minutes from where I parked my car. Based on my experience with the extreme winds we get, especially on exposed, elevated building facades, I don't think anything other than native species will survive. I'm really looking forward to seeing this, although it's not clear I'll be able to get into the building, lol.
