Back in 2006 when I was living in the Himalaya mountains, I was fascinated by this plant whose leaves were arranged like a necklace.
While most trees grow straight up and have their leaves grow in straight lines out from the branch, this plant does things differently. It chooses a point in space near it and then it grows its stalk in a circle to form what looks like a necklace of leaves around that point.
It even makes sure that the leaves each grow to a particular size so the central one is the biggest and longest and on either side of it the leaves get progressively smaller. The two leaves at either end of the circle, touch each other completing the necklace.
