I'd be tempted to grow this plant. Matter of fact I am tempted. Let me know when u want to part with an inch of plant.
I thik the coloring will stay. Its a stress response in most cases, and I'd assume the plant is just protecting itself. My L. Repens is red in patches of the leaf until it gets closer to the light.. Kinda neat actually, it's like it has clusters of places it needs to protect from too much light,maybe these areas of the plant have less chlorophyll? Maybe they have more and that's why it needs protecting in areas?
Either way coloring is stunning. And whine u wanna part with an inch or so of stem with a leaf or two, I'll take it.. Might even be worth the drive to ur area. I think ur two hours away
