Bill will present an illustrated program featuring "benchmark" perennial selections proven to offer the best results for landscapes enduring the environmental rigors of the lower Midwest, recently introduced perennial selections with potential promise to exceed the attributes of "benchmark" selections, and evaluation of all perennial selections presented from a "sustainability in the landscape" perspective based on experiences and  observations.  Sustainability criteria include water requirements, pest management, climate impact, invasive potential, diversity support, critter resistance, longevity and overall durability.

Bill's presentation is scheduled for Tuesday, July 10, 2018, 6:30pm
