This exuberant, orange flowered vine seems to launch itself off the side of a small two story residence. I love the contrast of the vine with the equally excessive, overhead power lines. The vine is part of the amazing multi-family residential building that is entirely covered in plants, which I included as part of a vertical garden comparison.

The name of this flower is ノウゼンカズラ（Campsis grandiflora). One of my favorite summer flowers around here.
This genus is one of the many that spans East Asia and Eastern North America. Campsis grandiflora is native to East Asia, while Campsis radicans’s range is from Florida to New Jersey, west to Iowa and Texas.
