Our Volunteer Sundays were instituted by former Curator Ellen Dean over a decade ago for working people who would like to remain part of the herbarium community. We prepare tasks that require a lot of person hours to complete, but which allow for socializing. It’s typically a convivial group of 6-12, some of whom have been coming to these for a long time, others are new. You can drop in any time during the four hours we are open. We provide refreshments and you are welcome to bring some too.
