This plant has a wonderful smell
Thank you for attaching the image of what appears to be an interesting shrub.
To obtain first hand assistance to identify the plant, I suggest you contact the Master Gardeners at the Contra Costa County Extension Service office. Contact information is here: http://ccmg.ucanr.edu/.
The Master Gardeners welcome walk-ins, phone calls, and emails. If you go to the office, take a sample branch about 12-inches long. If you email, attach at least 2 images, your close-up view as is posted here, plus one of the entire shrub.
Also helpful to include will be the plant’s history, as you know it. If it is a plant you saw elsewhere, describe what you can. If it’s at your place, include details of age; size; where planted (pot or ground); if it flowers, at what time of year and the flower color and shape.
Good luck with your quest and your gardening endeavors.
