Interesting...

What areas will tulip poplar thrive in the US?  When
can you harvest?  I assume you are addressing OSB as
a primary end use...

Carolina Pacific International, Inc. is on a similar
track with regard to the promotion of an extremely
fast-growing patent-applied-for variety of paulownia.

First possible harvest for most southern US plantations
would be at the end of the fourth growing season; trees
should have in excess of thirty feet of meaningful growth
and a DBH exceeding eight inches.  Growth in colder parts
of the US will be slower.

I invite you to visit my rather primitive home page:

I welcome your comments and suggestions; we may be on some
common ground, the result being beneficial to all.

End use: OSB or veneer for chords and/or webs of structural joists. It thrives 
East of the Mississippi & South of New England. See "Silvic of Trees of the 
United States", USDA-FS. Average site would yield 3300 cu.ft./ac. after 50 
yrs, And 4400 cu.ft./ac after 60 yrs. This seems like good practice assuming 
the site is promptly regenerated.
