Here's what the healthy ones look like.

Just cut the plant off the rhizome and clean it off, clean it and repot it in new soil.

My guess is that the red is from the sun. Beefsteak might be a reference to being red like a tomato.

That's wild!

I assume the pests were effectively controlled by mother nature(the one thing that cured my scale issue). I can't say enough for the power of the food chain. There are so many hungry predators out there!

If you periodically "recharged" the red,it would be neat to exhibit them side by side as a conversation piece. :)
