Wood
AceSV:
I just realized that http://www.wood-database.com/ has material property values for the more common types of wood. If someone knows where to plug in which value for Putnam's Material Helper, that would make things really easy.
Here is White Oak, which I would love to compare to the current material properties for wood

Alfrodo:
How about the Princess Tree?
They grow insanely fast, flower nicely, have useless fruits, and are invasive.
Not valuable, I just like this tree.
EDIT
Putnam:
Elastic modulus almost surely refers to young's modulus; the material helper has a rule-of-thumb for poisson's ratio for woods IIRC, so you could use that if info is not available; modulus of rupture can be considered tensile strength, AFAIK; crushing strength is definitely compressive strength.
AceSV:
These seem kind of zany

Also, the real price of lignum vitae is through the roof. I decided to just make the rare woods as valuable as silver/porcelain/crystal glass.
Putnam:
what in the world is causing such a low bulk modulus
