Anyone know much about this plant? Was told it need iron to produce the
reddish look, or else it's just a pink green plant...

I have this plant. New leaves look pinkish. I am just doing KNO3, K2SO4,
KH2PO4, MgS04, and Trace mix every other day.

how does it propogate, it's a bunch plant, just snip the top and replant?

Like a Weed. Put out roots every node.
