Green Roof Plant Trials for the Central Great Plains

Forty-three taxa representing native and adaptable plants were trialed for 4 years on an irrigated
(as needed) 15 cm (6 inch) deep extensive green roof in Lincoln, NE. Twenty-three of the taxa
showed good performance with minimal maintenance. At the end of the trial in fall 2014, 32 of
the taxa still had at least one specimen surviving. Drought impacts in the trial’s second year
eliminated several taxa. Presented here are results and the positive findings of four new extensive
green roof taxa, Festuca cinerea, Carex glauca, Eragrostis trichodes, and Distichilis spicata
