2017 PPA Symposium Sponsors

Each year, hundreds of Green Industry professionals from around the world attend the largest industry event focused exclusively on perennials in the U.S.—the Perennial Plant Association National Symposium. Businesses who sponsor our event gain essential brand exposure through our onsite signage, online coverage, post-event publications, and by providing one item to distribute in each attendee’s tote bag. 


We would like to express our sincere thanks to those sponsors shown here who have agreed to provide our event tote bags, water bottles, name badges, as well as sponsoring our coffee breaks, the Tuesday evening reception at the Denver Botanical Garden, and the Friday tour dinner in Vail.
