AlyssaBlue: I have an Arborvitae that looks exactly like that - planted it 3 years ago and every year it grows taller and wider. The bush in question, however, has a different look to it, esp. in that it's more triangular, seems to have different roots where one part of the plant goes off to the side so that it starts to look like it's separate (or two growing together as someone mentioned earlier). The color is also a little darker and it seems like the plaits/braiding seem more tightly woven. And as previously mentioned, the appealing swaying it does when pushed is unlike the movement of the tall, straight growing Arborvitae I planted.
JRsbugs: Gosh, that photo looks really close, foliage as well. My seed pods may not have that center beam quite as much as your photo shows, though.
Daisyl: Good point about the different sizes in different parts of the country.
