They are the ones who would be the souls of the plants we work with, for they like to work qwith us and share the plants secrets with us. But, only if we do so with a pure heart and with repsect.  They can teach us about the plants medicinal properties, nutritional values, it magickal qualities, its spiritual uses, whether or not it is poison or not!  It takes patience to work with these fairies, as it does with all fairy!  When you meet one it will show up as a glowing or flashing light that comes from the plant we seek knowledge from. You will feel its presence thru a tingling or warm sensation.They never leave their plant so finding them in some ways is easier, for they are there. But treat them and their plant kindly, with pure intentions and they will teach you much!
