Grass Identification Guide: What Type Of Grass Do I Have?

For too many homeowners, lawn care is dictated through a trial-and-error process. It can often feel frustrating when you’re trying to figure out the correct way to care for your lawn, and nothing seems to be working. To adequately care for your lawn, however, you’ll first need to identify the type of grass you have! 

Grass is classified according to the climate it grows in, either being a warm or cool season grass. Considering your climate is the first step to narrowing down your grass type. The specific type can be found by observing the grass’s color, appearance, growth rate, and tolerance to different conditions.  

For those trying to determine what type of grass they have, our identification guide will help you figure this out once and for all. First, we’ll take a look at the two main categories of grass types and tips for successfully identifying your relevant species. Once we’ve done this, we’ll break down the most common grass types! 

Understanding Different Grass Types 

When it comes down to identifying your grass, you first need to consider your climate. This will allow you to narrow the number of possible grasses, ultimately making it easier to identify your specific type of grass. This will come in handy when we outline the most common grass species.

Overall, there are two main categories of grass: cool-season and warm-season grasses. The type of grass you have will correspond to the climate in your region. However, you may also fall in a transition zone, where either type of grass may appear. Let’s take a look! 

Cool-Season Grass 

By considering your region’s climate, you’ll be able to figure out whether or not you have cool-season grass. If your region has hot summers and cold winters, then your grass will be a cool-season type. Regardless of how cold it gets, cool-season grasses will remain luscious; this is the best seed for those trying to keep their grass green over winter

In the United States, cool-season grasses are the most prevalent in the northern half of the country. With cool-season grasses, lawns will thrive in spring and autumn, when temperatures are cool. The ideal growing temperature for cool-season grasses is between 65- and 80-degrees Fahrenheit. 

Warm-Season Grass 

Originating in tropical regions, warm-season grasses are those that thrive when temperatures are between 75- and 90-degrees Fahrenheit. Due to this, these grasses will be at their greenest during the summer. In the United States, the southern half of the country is most likely to have warm-season grasses. 

During autumn and winter, however, warm-season grasses will generally go dormant until spring. This dormancy is even known to happen when temperatures exceed 90-degrees Fahrenheit. However, consistent watering can be used to combat this during the summer season.

Transition-Zone Grass 

As mentioned earlier, there are certain regions where both warm- and cool-season grasses are likely to develop. Generally, these areas are referred to as the transition zone, which is a region in the middle of the country. This region has the most variety in terms of grass types. 

The following states form part of the transition zone in the United States: Arkansas, Kansas, Kentucky, Missouri, North Carolina, Northern Georgia, Northern Mississippi, Northern Texas. Oklahoma, South Carolina, Tennessee, and Virginia. If you reside in these states, you might have cool-season or warm-season grass. 

Tips For Successful Grass Identification 

Before we consider the specific types of cool-season and warm-season grasses, we’re going to give you a few tips to help you identify your grass! 

Inspect The Color And Appearance Of The Grass 

When identifying the type of grass that you have, you’ll want to pay careful attention to the color and appearance of your grass. This will come in handy when you’re identifying it using our guide. The color and size of your grass blades are critical determining factors. 

You’ll also want to monitor how your grass is spread out. Different types of grass may even have different patterns or identifying features. By monitoring this, you’ll be able to accurately identify the type of grass you have. 

Consider The Growth Rate Of The Grass 

To accurately identify your type of grass, you’ll need to have a good understanding of the rate at which it grows. For example, do you know how frequently you need to mow your lawn? By observing how fast your grass grows, and when this takes place, you’ll be able to figure out which species of grass you have. 

Of course, the rate at which your grass grows will fluctuate throughout the different seasons. It’s essential to take note of this, as it will allow you to better care for your lawn in the future. Ultimately, your grass’ growth rate in different seasons is an important indicator as to which type of grass you actually have. 

Monitor The Tolerance Of The Grass 

Like the above tip, this one takes a bit of time. That is, you’ll want to consider the overall tolerance of your grass in different conditions. In the same vein as monitoring when your grass is thriving and growing quickly, you’ll want to monitor when your grass does poorly. 

Not only will this allow you to successfully identify your type of grass, but it will allow you to tailor your lawn care to your specific type of grass. When considering your lawn’s tolerance, you’ll want to monitor its performance in different temperatures, scorching and cold extremes. However, you’ll even want to consider how your lawn tolerates perpetual aspects like shade. 

Identifying Cool-Season Grasses 

If you suspect you have cool-season grass, it’s likely one of the following types. With the above-discussed tips in mind, you’ll be able to identify the specific type of cool-season grass that you have!  

Creeping Bentgrass

When it comes down to cool-season grasses, this is the most common type found on golf courses. This type of grass grows particularly well in coastal areas with high humidity levels. While this type of grass makes for great putting turf, it can often invade people’s lawn, growing alongside a different kind of grass. 

This type of grass has light patches that can be anywhere from 6-inches to 2-feet in size. Creeping Bentgrass has a horizontal growth pattern and only develops a shallow root system. During the summer, this cool-season grass will turn brown. 

Fine Fescue

Fine Fescue is a versatile cool-season grass. This type of grass is known for growing at high altitudes and thrives when temperatures are moderate. Of all the different types of cool-season grasses, Fine Fescue is the one that is the most tolerant to shade. 

Fine Fescue is characterized by fine, vertical grass blades that are a medium to dark shade of green. This type of grass is able to tolerate summer and winter climates and keeps its color throughout all the seasons. Another identifying characteristic is the slow initial growth rate of Fine Fescue. 

Kentucky Bluegrass

One of the most commonly found cool season grasses, Kentucky Bluegrass can be found across the United States. While this type of grass thrives in colder temperatures, it has a moderate tolerance to warmer weather. However, Kentucky Bluegrass will struggle to grow in shaded areas and during periods of drought. 

This type of cool-season grass has medium-sized blades that have a dark green color. However, this color will be most prominent during late spring and can often last all year. With this type of grass, homeowners will note a high growth rate, which means more mowing and fertilizing! 

Perennial Ryegrass

Tall fescue is a grass that is able to grow in a variety of different climates. Due to this adaptability, tall fescue is also commonly found in the transition zone. This type of cool-season grass requires less watering than other types due to its deep root system. This type of grass features medium blades that have a rich shade of green in spring. 

As far as cool-season grasses go, tall fescue is considered the most tolerant. While this grass thrives in cool temperatures, it’s able to tolerate heat and drought better than others. The time you save watering this grass will likely be spent mowing due to the quick rate of growth. However, it should be noted that tall fescue doesn’t spread to fill bare spots as it is a bunch-forming grass.

Identifying Warm-Season Grasses 

For those suspecting they have warm-season grass, it will likely be one of the following grasses. We’ll give you a breakdown of the most common types, which will allow you to properly identify which type of warm season grass you have! 

Bahia Grass

Like Centipede grass, which we discussed above, St. Augustine grass is well-suited to regions with warm climates and high levels of rainfall. The moisture produced by the humidity of these regions is essential to the growth of this grass. In cold temperatures, when there’s little moisture, St. Augustine grass will struggle to grow and will lose its color. 

This warm-season grass has a light to medium shade of green, which is most prominent during warm weather. This grass has wide blades and will grow rapidly. While this grass struggles to tolerate foot traffic, it can still thrive in the shade. 

Zoysia Grass

As far as the different warm-season grasses go, Zoysia grass is one of the most versatile. Due to its ability to grow in a variety of different climates, this type of warm-season grass is commonly found in regions in the transition zone. This grass is known to be lower maintenance than other types. 

Like most warm-season grasses, Zoysia grass has a light to medium green color. The pointed blades are medium-sized. While this grass grows at a slower rate than others, it will be highly resistant to foot traffic. Furthermore, this grass will handle drought and extreme heat very well! 


There are two main types of grasses, namely cool- and warm-season grasses. However, in certain regions located in the so-called transition zone, it is possible to find either type. In order to identify your type of grass, it’s important to consider your climate. 

You’ll also need to pay attention to how your grass grows: when does it thrive, and which conditions does it struggle to tolerate? By considering these aspects of your lawn, you’ll be able to identify your type and tailor your subsequent lawn care to your relevant type of grass.
