Must disagree with this. You should look a little harder. I have many
board feet of really tight grained, vertical sawn, dry, straight
hemlock (not hemfir, a fast growing commercial mutant wood) found right
in the trim/banister section of our local Sutherlands. ...

Splorf! It sounds like you got your species information from a
clerk at the Home Depot. The last ime I asked one iif their
Hem-FIr was Helock or Fir he said it was probably a hybrid!

Hem-Fir is a softwood lumber association _species group_, like
SPF, only one level higher up in quality. Hem-Fir may be Western
hemlock or any of several Firs, it won't be any species of pine,
larch, Doug Fir, or spruce and the minimum tensile strength
requirement for that group is higher than for SPF, but lower than
for Southern Yellow pine, or Doug Fir.

It may be fast grown or not, but it isn't a hybrid or a mutant any more
than SPF (Spruce, Pine or Fir) is a mutant or hybrid wood. Most
Douglas Fir and Southern Yellow Pine sold by the Borgs IS fast
grown and bears little resemblence to old-growth despite being the
named genus, or group of species.
