hey dwight
for sierra junipers contact bob shimon at mcbonsai.com
he's allways got some nice ones.
i acquired a real nice one from him last year.
here's a pic of my sierra juni.
You can have this monster - now doing very well after transplant to a grow box - if you want to come pick it up. It's apparently a Utah juniper. Going to be a beauty some day, and it'll do better in your climate than mine over time.
We can haggle price if you want to, but it's not an issue with me: my long-term goal is to see to it that you have in your collection a juniper of every known variety.
