Stinky

We have this plant in our side yard (in fact, it may be growing in our neighbor's yard altogether), which stinks to high heaven. The flowers do, in the spring. it also gets a few red leaves among the green ones, which fall off easily. Stinky, but very beautifully colored: white flowers, and green and red leaves. Based on the colors, it's either Merry Christmas, or best wished to Ghana!
