Timber post supplier

I've had a hard time finding poles or landscape timbers longer than 8'.  I can easily get dimensional lumber that is more than 8' in length, but for certain garden construction projects it really improves the project aesthetics to have a more rustic or natural look.

For example, in England we observed that climbing roses were often trained up a solitary pole, a practice I subsequently learned was called pillaring. Yes, it's a verb.  The poles resembled branches or trunks of small trees, which added to the naturalistic effect.  The major big box stores (HD, Lowes) have landscape timbers (flats on two opposite sides, curved on the adjacent sides) and poles in 8' lengths.  Armstrong had stakes (~2-1/2" diameter pressure treated round lumber) in 8' and 10' length.  These were all deemed too short (about 1/3 of the above-ground height should be in-ground for stability) and too thin (a substantial look is desire, so maybe a minimum of 4" diameter was wanted).  Ganahl had a similar 8' (max) selection, but referred me to my new favorite garden supplier C & E Lumber (CElumber.com).  They _specialize_ in posts.  Who ever heard of that??!  I can't wait to visit.
