childbearing year - plant/flower/herb

I am a doula, I work with women through out the childbearing year.  I am interested in finding a plant/flower/herb that represents the power of women in this time of life.  I am hoping to use it as a logo and so want it to also be beautiful, maybe purple.  Any suggestions?

Thank you so much
