I've specially seen the plants of kali haldi. Read lot of scientific articles online from various research scholors. For palash some of my north friends keep that on their back-yard for their religious beliefs. They treat it as "money attraction plant" and incornation of Goddess. Of course, it is a herbal plant widely using since centuries.

hello sir

can I get those plants? where are you growing sir? I want black turmeric plants (10) and one white palash.

I do not mind it. You have limited knowledge or some one might have fooled you giving a purple termeric saying it is black. You can test it yourself. Uproot it and scratch it. It will show purple color. I am 100% sure. The reason why I say is I have both PT and BT ( Not even a single purple stain in my BT). I need not ask any one. And I have nothing to do with your plants. You posted to Indentify your plants, Keep big mind and heart to accept what is true.
