National Symposia

The yearly Perennial Plant Symposium is the oldest and largest symposium in North America devoted entirely to perennials.  The location changes each year.  Enjoy learning about and observing perennials, gardens, and production facilities all across the USA and Canada. Our Events section has more detailed information.

Regional Symposium

In fulfillment of a mission to offer outreach education, the PPA conducts regional symposia in locations throughout the PPA membership locations.  In 2009, events were hosted in Wisconsin and Columbus, Ohio.  In 2010, the Minnesota Landscape Arboretum and the PPA teamed up for a first-class program.  In September 2010, the Northeast Regional was held at the Elm Bank Horticulture Center of the Massachusetts Horticultural Society. 2012 shows great promise for the regional symposia. In February, the PPA and Maryland Horticulture Society teamed to host a symposium in Baltimore and there will be a regional symposium in Boston, Massachusetts as well.
