Answer: Plants with golden foliage do normally turn greener in shadier sites and will be the brightest gold in full sun. In addition, younger foliage on this plant is a sort of chartreuse and matures as the summer progresses to a more golden color. So the color change is probably normal. If however the edges begin to brown or you see browning overall, or if fall coloring begins to develop prematurely, then it would not be a healthy change. Since this is a new plant, I would suggest you consult with your retailer if you are still concerned about your new plant.
