Fouquieria splendens
Ocotillo

Ocotillo is very common in Arizona. The essential challenge is accessing the clusters of flowers that grow at the tips of 10-20 foot long thorn covered branches. Fortunately, those branches are fairly flexible and with some care they can be bent down within reach. Then with the help of an able bodied assistant you can take your picture. Flowers are pretty much odorless, in case you were wondering.
