Because of HLB, there are restrictions on moving citrus plants in California. You'll have to find one from someone nearby or get one from a nursery that sells plants that have been inspected.

This variety isn't available via the UC Riverside Citrus Clonal Protection Program (CCPP), so I would imagine you're going to have significant difficulties find this cultivar in the state of California. As legteacher has mentioned, you would have to know someone very close to you (restrictions are in place here in California from moving citrus around, even within the state), or know of a grower who can provide an inspected tree for you. I have never seen this variety here in S. California, myself. Seeds cannot be sent into the USA from out of the country, either, so don't try to do that, or you may find a USDA inspector at your door.
