What a great thread!
Yarrow was a friend of mine as a child. I loved her smell and used to gently crush a few ferny leaves and sniff them. I also loved how the leaves would stay green down close to the ground all winter. One year when I was seven I gathered yarrow "for the winter" and laid it out in baskets to dry. If only the grownups had known how valuable it is they would have bagged it up and kept it.
I also played with rose a lot. I would make little fairy dolls by sticking rose petals on a tiny stick to be the fairy skirts. Sometimes I would pick a rose and use it as a cup. It was some kind of ritual for me to drink from a rose.
I also loved dandelions and would lie on my stomach and lick the nectar and pollen from the middle of dandelion flowers without even having to pick them.
I also used to snack on sorrel and shepherd's purse.
Interestingly enough, yarrow was the plant that really drew me towards herbalism in my teens. I'd gotten athlete's foot at the pool and I read somewhere that yarrow would help. I gathered some wild yarrow right from our yard, made an infusion and soaked my feet. I only did it twice but the athlete's foot went away. My mom had a cold and so she drank some of the infusion too. It was really strong and I told her I just made for soaking not for drinking but she drank it, sputtering all the while. It helped her cold too. I was intrigued and began to study all I could about herbs. Yarrow is still one of my very favorite herbs.
