The proper way to find the answer to your question is to use the "Search" tab on the main page. Enter the rose name, "Los Angeles" and click search. This will take you to the rose page for Los Angeles. To the upper right of that page, you will find the tab, "Buy From", which will display the nurseries who most recently listed this rose as available. Currently, that will show you two nurseries offering it as of the most current information. Vintage Gardens is one, but their web site states it is on Custom Root currently. The other nursery is Rogue Valley Roses. I can't tell from their web site if this rose is available from them, so you should go to their site and contact them to determine if they can supply it.

By using the tabs across the top of the rose pages, you can find out much of the information yourself, much more quickly than posting this type of inquiry to the Q&A section, saving you much time.
