Thing of Many Names...
This rose, according to Jeri and others, has been found all over California. It now exists in various public rose gardens under about 15 study names! No kidding - every time it was found it got a new name. They have looked carefully at most of them, and decided it is all this one rose. No identification yet. So, now it is being called the "Thing of Many Names".
I took this picture of mine today. It is a rooted cutting from one I found a block from my house growing in the garden of a house built c. 1900. The lady who lives there has lived there for 60 years, and says it was there when she moved in.
Very fragrant, and blooms all Summer. Mine is only about 4 years old. Here is a pic:
