Re: Oak-ID from this description?


From my recent Western Garden Book:
Quercus: 
Q.bicolor  Swamp White Oak  Zones 1-3
Q. coccinea  Scarlet Oak  Zones 1-11  Roots grow deep  Fine to garden under.
Q. gambelii (Q. utahensis)  Rocky Mt. White Oak  Zones 1-3
Q. lobata  Valley Oak, Calif. White Oak. Zones 1-9
Q. macrocarpa   Bur Oak, Mossy Cup Oak  Zones 1-11.  Similar to Q. bicolor
but faster growing.
Q. palustris. Pin Oak  All zones.  [ It's a black oak.]
Q. rubra  Red Oak, Northern red oak. Zones 1-12  [Another black oak]

Macrocarpa and palustris you remembered.  Palustris 'fine tree for lawns'
seems to indicate deep roots.  

Don't want to type up the whole page, but ask if can answer more.  The zones
mentioned are Sunset zones, not USDA.

Good luck.    Carol
