Shimpaku identification to air layer

Hi.
Looking for some direction in learning how to identify a Shimpaku from other junipers.
I live in So. Cal. And, I find myself looking at all sorts of potential plants to air layer.
But want to only air layer Shimpaku…
Thanks in advance,
V

The best way to identify shimpaku is to become familiar with them in person. Most southern California bonsai nurseries will have shimpaku - visiting one could be a good place to start. Chikugo-en is well-known for shimpaku bonsai, among other species.
