Perennials: What is wrong with my Houttuynia (Chameleon Plant)?, 1 by ButterflyChaser

I know many consider this a weed. I'd like it if it retained the colorful foliage it had when I first got it years ago. The citrus scented leaves are delightful, altho it is an aggressive spreader.

When I first got it, it was so colorful with lots of red on the foliage. Over the years, it's lost the red and light green and the foliage is now always just plain green. I have it growing in both sun and shade, in dry and moist areas, with the same results. My soil is very rich and everything else I grow in these areas do beautifully. So why doesn't my chameleon change colors like everyone else's? Is my soil deficient of some nutrient it needs?
