You can try Champa nursery in El Monte, but I don’t recall if Jimmy at Champa has them. Best to give him a call.
Btw, I recall someone once telling me that Tropical Bonsai Nursery (Charlie) is the house/property next door to Champa, but I have never independently verified this.
Perhaps you can try Mimosa(East LA), but I have always felt their prices were quite high.
Unfortunately, you have desired an item that has a somewhat limited number of local vendors, and hence, commands a higher price.
