Well i see someone has allready identified it for you. It is indeed a bottlebrush, that's about the only plant i can identify as i have one in my yard and so does my mother, she got her's to bloom twice this year, but mine only bloomed once. She tells me they need lots of water. Hummingbirds love them.
Bottlebrush - native to Australia but really common in warm climates - like Southern California...lol! We have them everywhere. I just looked it up and the name is, "callistemon." They're really pretty flowers. Wonderful shot!
