I've been studying Rosy Dock.  This is some of the information I've learned:

Rosy Dock is a short red weed - look at my picture!

If you wanted to know what eats it... people do!!  It's used as a medicinal tonic for the cure of ulcers and sores.  It has a cleansing effect on teeth.

I'm amazed that nothing lives in it!

It has long roots to survive in the desert.  You can find this terrible weed in the USA, Canada and Australia.

I enjoyed reading the book "Rosy Dock" by Jeannie Baker.
