Tom Moseley was one of those lawn-mowing kids who found out he liked working outdoors, so he took more and more landscaping jobs and learned a lot about plants, especially trees, and ended up creating Maryland Gardens Tree and Shrub Farm in Potomac, Maryland. I can't give you a link to his business because, as I learned, Tom would have to buy a computer first, something that interests him not a whit. Yes, he's a Neanderthal but an endearing one, I tell you, because he loves trees and shrubs and seems to know everything there is to know about them.
At least Tom's enough of a businessman to have a brochure and it lists the roughly 10,000 trees and shrubs he grows and sells, all from seedlings. And when I called to see if he had five 'Green Giant' Arborvitae - heck, he had 100 of 'em; what size did I want? Well, I wanted the cheapest size so they're only 6 or 7 feet tall, but that's a lot of tree for $75 each and they grow really fast.
Why the 'Green Giant', you ask? Because several lecturers in my Master Gardener School have warned us against ever planting Leland Cypress for screening, as landscapers have done by the millions over the last few decades. One PowerPoint included a 15-minute section entitled "What's wrong with my Leland Cypress?," the answer to which was long and multifaceted. Everyone seems to be recommending the 'Green Giant" nowadays, for its evergreen columnar shape, its fast growth, and its resistance to the myrid problems that afflict Lelands. I happened to buy one from Tom two years ago and it's doing great - in a crappy location - so I needed no convincing. And here's Tom with the five I bought, ready to be loaded into my small but useful Honda CRV for the ride home.
