Missed this thread last year while I was working way too much, but here are some I believe fits the theme. Chalk Maple Acer leucoderme Southern Sugar Maple Acer floridanum BigToothed Maple Acer grandidentatum American Fringe Tree Chionanthus virginicus The already mentioned. Yellowwood Cladrastis kentuckea(lutea) Decidous Holly Ilex decidua (allot of this native locally and it looks great in winter) Acer pseudosieboldianum Acer triflorum Acer griseum White Oak Quercus alba Scarlet Oak Quercus coccinea Chinkapin Oak Quercus muehlenbergii Carpinus caroliniana On a related note, here is one to look up. Ozark Chinquapin Castanea pumila var ozarkensis Work is ongoing to develop blight resistant trees.

Many of the suggestions are trees that easily get 60 - 100 feet tall. Camphor is invasive and has an aggressive root system. In fact most large trees eventually have large root systems that interfere with this and that. Select the smallest tree that will do the job you want it to do. In the long run you will save yourself money and trouble. Also figure that the tree will get a little larger than the estimates you read on the label or in the description. Many trees are listed for their size after 10 years of growth--eventually they will be larger. Cal Poly Tree selector is a nice site for suggestions. Also check the Sunset Western Garden book for "trees to plant near swimming pools", not because you have a pool but because trees that are good near swimming pools have well-behaved root systems and are pretty clean. I'm finding Agonis flexuosa to be a very nice small tree (25' is considered to be a "small" tree). Clean, well behaved, deep root system. Here is a link that might be useful: Cal Poly SLO Selectree

Nothotsuga, you inferred I don't care about diversity of the world because I wasn't interested in the number of conifers native to California. Of course I care. I just wasn't interested in the number. Clearly California is the area in the world with the biggest number and biggest diversity of Cupressus species. About a third of all Cupressus species are growing there and 8 species are even endemic to California. If you just are not interested in the number of Cupressus species in California, it means clearly that you are not interested in their diversity. And the diversity of Cupressus species is part of the overall biodiversity. Moreover several of these species are in great danger of extinction due mainly to too frequent fires set by people, voluntarily or not. Not caring about their number, you don't care if one or more Cupressus species will go extinct. "botann" maybe, but far from a botanist, imho.
