Will you be using the border along the ceiling or chair-rail ?
IMO that's a lot of green.
If it were me...I'd use the green (maybe paint instead of paper) on the half of the wall, chair rail about 3 feet up and add a coordinating print (stripe or smaller floral print) along with the magnolia border. Without seeing a third swatch I can't decide which order I'd place them - whether the border would go above the rail or along the ceiling, and whether the solid color/print goes above or below the chairrail.
