Greengrocer

The Greengrocer is a woman who can be found between two buildings across from the Saloon in Soccoro (Oregon). She is where you begin the "They taste yummi" herbalist missions. I believe that these herbal missions are only available through the update since I have not seen her in the Windows Phone version. If you're having trouble finding her, use the road sign to travel to Socorro. Turn slight left towards the well and you will find her behind those buildings.
