On my site http://www.freewebs.com/scer16smodels/ I made a tutorial on making realistic trees (select it on the left) and since the pic is gigantic there, Ill post the finished result here.

Some people suggested to paint the parsely so it doesnt change color, but I first used 10 yeaar old parsely and it was a light shade of brown, perfect for late summer/fall

Last tree i made 2 days ago i used dried parsley and mint , for cooking and they had a deep green colour that with some matt varnish went even better
