Common Mallow or Malva Neglecta is related to Hollyhock.
I learn the definition of each plant primarily by connecting to the deva of flower essences. I sit with my empty notebook and take a drop of the the essence and strongly picture the plant in my mind. Then I write down what I feel. To verify the information I've received I, sometimes, cross check with other essence practitioners to see what they have gotten. Other times I give the essence to a sensitive friend(s) and write down their reactions. I will also cross reference with my plant spirit journeys (which have already been crosschecked with by a group of apprentices). I usually do all three.
