Different Types Of Grass: How To Identify Your Lawn's Grass Type

Ever wonder why your neighbor's lawn stays green through winter while yours goes dormant and brown—or the reverse? The answer usually comes down to grass type. There are around a dozen common lawn grasses in the US, and many home lawns can actually be a blend of two or three grass types rather than a single variety.

Knowing your grass type is the foundation for every other lawn care decision you'll make: when to plant, how often to water and feed, and even which products are safe to use. This guide walks you through identifying your grass, then routes you to a full profile and growing guide for whichever type (or types) you find.

Many US lawns are made up of one or more of about a dozen common grass types, which fall into two broad categories: cool-season grasses (found across the northern two-thirds of the country) and warm-season grasses (found across the South). Start by figuring out which category you're in, that helps narrow things down fast, then use the profiles below to zero in on the exact type.

The fastest way to narrow down your grass type is to look at when it's green and when it's dormant. Cool-season grasses grow most actively in spring and fall and usually stay green through mild winters. Warm-season grasses grow most actively in summer heat and typically go brown and dormant once temperatures drop in fall.

Start with where you live and when your lawn is greenest. If your grass is green in spring and fall and struggles or browns in peak summer heat, it's almost certainly cool-season. If it's green and growing all summer but turns brown shortly after the first cold snap, it's warm-season. Homeowners in the middle "Transition Zone" (roughly the mid-South) may see either type, or a mix of both.

Four cool-season grasses make up nearly every Northern lawn. Kentucky bluegrass, perennial ryegrass, and fine fescue are frequently blended together in one seed mix—often sold as a Sun & Shade Mix—since each type brings a different strength to the blend. Tall fescue is usually grown on its own rather than blended, with one common exception: a Drought-Tolerant Mix that pairs tall fescue with Kentucky bluegrass for lawns that need both heat tolerance and self-repair. Here's a quick look at each type. For a full profile of your growing region and care needs, jump to its section on What Are Cool-Season Grasses?

Five warm-season grasses cover the vast majority of Southern lawns, each suited to a slightly different climate, soil, and maintenance level. Jump to its full profile on What Are Warm-Season Grasses? for planting and care details.

A few additional grass types, plus a couple of non-grass ground covers, can also be grown as lawns. They are usually region or use case specific rather than “typical“ home lawns.

Your grass type determines nearly every other lawn care decision: when to plant or overseed, how often to water and feed, how low you can mow, and which weed and pest products are safe to use. Using a product or timing meant for the wrong grass type, like feeding a warm-season lawn on a cool-season schedule, or mowing Zoysia as low as Bermuda, can stress or damage your lawn instead of helping it.
