Where I live the name the name Cedar is very commonly used for company names – for all sorts of companies, everything from cafés to estate agents.
According to the Woodland Trust in the UK, cedar was planted in nearly every stately home and mansion from the 1740s onwards. I guess this explains the use of this tree name for businesses. Stately homes and mansions – maybe cedar is supposed to make the company name sound posh – well.. it is, of course, the wood used for posh pencils, too.
Why do I mention this? A few weeks ago I went to a place called Cedar Farm, a collection of shops in what used to be a farm and very fitting for the name of that place I found a book about pencils there. It is aimed at artists but does contain fact about pencils presented in a nice way (as usual: open the images in a new tab to see at full size)
