Q.My Virginia Creeper Only Turns Pink On The Underside Of The Leaves
I bought my Virginia Creeper last year in August and the leaves were only pink on one side, the underside. They have grown back this year with one side of the leaf dark green, the other side purple. Is this normal? It is still a relatively young plant with three leaves per leaf node not five yet.

Unfortunately, your photo did not come through.
Generally, the cold is what makes them turn color. They are only well suited for USDA zones 4-8. Your area is most equivalent to our zone 9. This means that you may not see the drastic coloration that we see here.
Young leaves can be slightly colored, but they should grow out of this. Any coloration outside of Autumn can indicate pH issues, nutrient deficiencies, overwatering, and disease. Without seeing the issue, it will be hard to say.
