I live in zone 7 and im looking for the best kind of grass. We get snow and ice in winter but in summer it gets sunny and hot and we sometimes get droughts. The lawn is a high traffic area and mowed frequently. We have zoyza grass but it turns brown and in winter looks dead and weeds grow in it easily. I also want the grass to help wildlife like anything that eats grass.

I was looking and perennial ryegrass is supposed to be great for what I need.

Have you looked at the Eco-lawn mixes? or the No Mow mixes?

Did you check out the Suffolk County healthy lawns site, they list some suggestions for mixes recommended for overseeding that I assume should be appropriate for your area:

Are you looking to sod, seed from scratch (prepared bare seedbed) or overseed?

Here is some information from Mike McGrath, one time editor of organic gardening:

I want to overseed

The mixes on the Suffolk County site are for overseeding so personally I'd go with their recommendation. They do explain the drawbacks with perennial ryegrass, and I'd be inclined to avoid using only one grass species anyway. It's OK to include some as it functions as a "nursegrass", but I was taught for that use not to exceed 20% of the mixture.
