Help! I just purchased my Crimson Queen and have not planted it yet. I noticed that the leaves are losing the red coloring. I don't know if this is frost damage because we did have a day that the temp reached freezing over night just about two days ago. This tree has been sitting on the east side of my house, not 4 feet away. It's gets sun up until about 2:30, but it's been cool here so even with the sun heat, I'm not sure it's been hot enough to harm it. The plant is not root bound and the soil has been moist. The leaves appear to be turning a very light color. I can't say it's green because it looks to be more off white or light yellowish. Is this frost damage, sun damage... please help.
Here's a picture of the problem:
