The colour of the blooms will determine the colour of the leaf and I'm guessing the stem as well. I have a white Phal that has green leaves and a dark green spike, i also have a really dark Phal (it looks like someone put molasses in a spray gun and sprayed the flower) and the leaves are a darker green and have reddish splotches all over them and the flower stalk it a dark burgundy/brown. It really depends on the flower. A picture would help.
