New grass in I-25 medians is natural seeding

QUESTION: Why are the slopes and medians along I-25/COSMIX being planted with grass, which requires regular mowing and maintenance, instead of something like self-sowing native Colorado wildflowers or ground cover, such as crown vetch? This would not only enhance the beauty, but would save on the mowing and maintenance costs in the long run.

ANSWER: It’s all natural seeding, not Kentucky bluegrass, according to the Colorado Department of Transportation. It won’t need sprinklers or mowing. The only median maintenance will be litter pickup or fence repair and some occasional weeding. No more “pristine green lawns” like they once had in the medians, says CDOT’s Bob Wilson.
