The calendula plant is waaaaaay more versatile than I thought! Prior to this, I had no idea that it's properties were medicinal at all! It was just another pretty marigold I saw people growing in their flower gardens... I appreciate the educational experience! :-D

Also, you mentioned the flower-part (the inflorescence) displaying the Fibonnacci sequence... I'm sure you know this as well - but almost all (if not truly ALL) flowers and pine cones (...and other reproductive planty pieces?) display the Fibonnacci sequence too! It's almost as if nature itself is trying to tell us something... :-)
