Chapters are formed when a group of people wish to expand the efforts of The Maryland Native Plant Society in a specific geographic region. Chapter boards address local issues and tailor programs to their own area's interests and needs.

Chapter affiliation is based on the member's address. Affiliation is automatically granted to each member within the appropriate Chapter.

Unless specified in the program description, all activities are open to the entire MNPS membership as well as the general public. Participants do not need to be members of the Society nor active Chapter members to benefit from our programs.
