HELP: Matching a tree beside flowers!!? Im getting a paper birch, and I required to find some...

Im getting a paper birch, and I required to find some flowers that match next to the tree in any season. The tree is origionally a feathery green. Here's a picture of the tree:http://i200.photobucket.com/albums/aa74/...
Answers:    my son has Lorapetalum shrubs beside his Heritage birch... they're a good complement next to the burgundy leaves and hot pink blooms.. consider, too, a Limemound spirea... neon chartreuse green and hot pink flowers. very pretty next to the birch.. yellow spill out color on the birch would call for hot reds and oranges, so figger on mums within white and punkins and asters for purple.
I have never hear of anyone wanting to match a tree but afterwards again i am not a landscaper. I thing some sickly ferns would go correct they are a green yellow and some bulbs close to calla lilies in the white or pallid or both would be neat. to be honest i really wouldn't know because i don't know what module of the country you live in.
