Rich soil

More accurately, Pandanus candelabrum grows on top of kimberlite pipes. These subterranean carrot-shaped formations were created by volcanic eruptions and are now replete with potassium, magnesium, phosphorus and diamonds.
The entire process is spelled out in an article published in the June-July 2015 issue of the journal Economic Geology in an article by Stephen Haggerty, a professor at Florida International University. Haggerty says he uses “diamonds as a proverbial window to Earth’s deep interior”.
He believes the plant has adapted to growing in these mineral-rich soils, providing a simple and efficient tool for identifying kimberlite pipes and potential diamond deposits. Kimberlite mining is less invasive than other types of mining because of the pipes’ narrow shape.
