Our Regional Roadside Mixtures project found several interesting trends:
- At several sites, turfgrass entry diﬀerences were not signiﬁcant for turf cover or change in turf cover.
- Alkaligrasses were top performers at rural sites in MN and NJ, but did not do well in MI, primarily due to poor establishment.
- Perennial ryegrass entries were often in the top statistical grouping at sites in MI, WI, and NJ (urban only) but did poorly in both locations in MN.
- At the rural site in NJ, only alkaligrasses survived through two winters, along with the only two DOT-speciﬁed mixtures that contained alkaligrass (see Regional Roadside State Mixtures).
- Strong creeping red fescue and slender creeping red fescue performed better than other species at urban sites in MN and WI.
