Couple Species Questions..

Bobby, I do not know much about Firs, either yours or Firs in general. I have read 2 or 3 authors of bonsai books who are rather negative on their qualities as bonsai, but have seen a few examples (not of your particular variety) that really weren't bad. My take on the impact of climate change would be pretty negative, especially one as extreme as the one you're proposing. Trying to grow trees in climates they are unsuited for them is tough to impossible. I don't think your Fir is likely to approve of being brought to Central Texas and will likely die a lingering death in your Central Texas heat.

Prospects are better with Ponderosa Pine. These trees are widely adaptable, though Central Texas is likely to be a stretch. They are popular as Bonsai, though the needles are longer than ideal. Lots of them have been brought down from the Rockies in the Denver area as well as other places. I'm not sure P. Pine would be my first choice among the pines, but alot of them do exist as very well done bonsai in this country.

You wll certainly have fewer problems with either trees that are native to your area or trees and shrubs commonly used as ornamentals which can be found in your area's nuseries in the Spring. Alot of us find that it is especially rewarding to work with species that are native to the areas we live in. You might want to investigate what's available close to home. Doing so is likely to turn up some surprizingly attractive species.

Good luck, Fred
