Species composition changes in a rooftop grass and wildflower meadow: Implication for designing successful mixtures

Based on our observations of a grass and wildflower meadow growing in 7 radiation zones on the roof of The Church of Jesus Christ of Latter-day Saints Conference Center in Salt Lake City, Utah, we identified 21 species that should be considered for future grass/wildflower mixture studies. We also found a single wildflower species and 1 grass species that were too aggressive for mixtures, and 4 wildflower species and 3 species of grass that were not aggressive enough. Mixtures of grasses and wildflowers can be aesthetically appealing, water-conserving, low-maintenance alternatives to conventional turfgrass.
