There are none. Back in the day.....early 80"s, that area was a fairly nice mecca of bonsai material.
San Lorenzo Lumber in Santa Cruz is where I bought my first tree. Had really nice large trees, 16" to 20". Now they have some starters from Ian Price (Lone Pine) which are over priced for what you get. It is still my favorite nursery in the state, but now I buy for my yard there.
Bones and Jones in Capitola had speciman bonsai, and really had some good material.
Yamagami's in Saratoga had wonderful material and most of Midori club bought material there.
Yamanaka Bonsai Nursery on Saratoga-Sunnyvale Rd. in San Jose was another bonsai nursery that was wonderful and had great prices.
I live in Felton (SC Mtns.) and I like to go to Redwood Nursery in Scotts Valley. They are located on the frontage rd. along side of Hiway 17 at the Mt. Hermon Rd. exit. This is a very old nursery and they have alot of older material to choose from, plus the owners are very nice. Pete
Hello....Some of the best material is not at nurseries. Its from some of the older members of the local clubs...Santa Cruz Bonsai Kai, Watsonville Bonsai or Monterey Bonsai....Check those place and see what you can find!
