How to Identify Buffalo Grass in Australia
Identify Australian buffalo grass via its wide rounded leaves, soft texture, surface runners and great shade tolerance. Distinguish it from kikuyu and couch, then follow tailored mowing, watering and herbicide rules for proper lawn care.
Standing in the backyard on a sunny Saturday morning, staring down at the lawn you inherited with the property, it is one of the most common questions in Australian gardening: is this buffalo, or is it kikuyu? Knowing how to identify Buffalo grass is the critical first step, because getting it right directly affects your maintenance routine, weed control strategy, and — most importantly — your herbicide choice. Use the wrong product on buffalo, and you can do serious damage to an otherwise healthy lawn.
What Does Buffalo Grass Look Like? The 5 Key Physical Traits
If you want to be completely certain about your turf variety, conducting a hands-on identification check right now in your own backyard is the best way forward. Taking a closer look at the distinct physical features of your grass will quickly reveal its true identity.
Leaf Blade Width and Shape
You can spot buffalo grass by its broad, flat blades, which usually measure anywhere from 5mm to 10mm wide, depending on the variety. If you take a close look at the very tip of the blade, you will notice it is rounded off rather than pointy. This is a dead giveaway when you compare it to common lookalikes. Kikuyu blades are narrower, sitting around 4mm to 7mm with a sharp, pointed tip, while couch is incredibly fine, usually measuring under 4mm.
An easy way to tell them apart right now is with a quick pinch test. Pluck a blade and pinch it between your thumb and finger. Buffalo will feel notably flat and wide in your hand, whereas kikuyu feels narrower and has a slightly hairy texture to it.
Texture — Soft Underfoot
Modern soft-leaf buffalo varieties such as Sir Walter and Sapphire are noticeably soft to touch and lovely underfoot, making them perfect for families. This pleasant texture easily distinguishes them from older, scratchier buffalo types of the past, and from couch, which feels much finer and stiffer.
If the grass in your yard feels scratchy and coarse against your skin, it is far more likely to be kikuyu. Keep in mind that older buffalo varieties can feel rougher, but the modern varieties dominant in Aussie yards are selected for comfort.
Colour — Deep Green, Even in Shade
One of the standout visual giveaways of this variety is its rich aesthetic. Buffalo grass holds a deep, dark green colour, particularly in shaded areas where alternative varieties like couch and kikuyu constantly struggle to survive. If you notice the shaded section of your lawn under a large tree or next to the house is still green and lush, that is a strong indicator of buffalo.
During the chilly winter months, buffalo may lose some colour intensity but retain green better than couch, which tends to go completely dormant and yellow.
Stolons (Runners) — Above Ground Only
Examining how your lawn spreads across the yard will give you an immediate answer. Buffalo grass spreads exclusively via above-ground stolons, which are horizontal stems creeping along the soil surface. This is a key differentiator because both couch and kikuyu possess underground rhizomes that dive deep into the soil, making them much harder to contain around garden edges.
A buffalo stolon looks like a flat, leafy stem running visibly across the lawn surface. For an expert tip, fold a buffalo leaf blade in half horizontally, and you will see a distinct V-shaped crease.
The Vernation Test — A Definitive Check
If you are still sitting on the fence, you can use the vernation test, which looks at how the grass leaf is arranged in the shoot before it opens up. Buffalo grass has a folded vernation, meaning the emerging leaves fold neatly inside the sheath. This structural trait is exactly what creates the characteristic V-shaped crease when you fold the blade in half.
On the other hand, couch grass has a rolled vernation, acting as a useful backup confirmation when unsure. This quick anatomical check is a genuine differentiator that most AU guides mention.
How to Tell Buffalo Grass Apart from Kikuyu and Couch
Buffalo and kikuyu are the varieties most commonly confused across Australia because both are warm-season grasses that spread via visible above-ground runners. Up close, however, the structural differences are clear. For a detailed breakdown of all three varieties side by side, see our full comparison of buffalo, couch and kikuyu.
| Feature | Buffalo Grass | Kikuyu Grass | Couch Grass |
|---|---|---|---|
| Leaf width | 5–10mm, broad | 4–7mm, medium | Under 4mm, fine |
| Leaf tip | Rounded | Pointed | Pointed |
| Texture | Soft, flat | Coarser, slightly hairy | Fine, smooth |
| Runners | Above ground only | Above + below ground | Above + below ground |
| Shade tolerance | Excellent | Poor | Poor |
| Winter colour | Retains green (most varieties) | Retains green well | Yellows/browns |
| Growth rate | Moderate | Fast / aggressive | Fast |
A practical rule of thumb: if the shaded strip near the fence is still lush and green, it is almost certainly buffalo. If grass is aggressively invading garden beds and you can feel runners underground, kikuyu or couch is far more likely.
Which Type of Buffalo Grass Do You Have?
Identifying the broader buffalo family is useful, but knowing your specific variety is what allows you to tailor your lawn care precisely. There are several buffalo grass types commonly grown across Australia, and each has slightly different visual characteristics.
Sir Walter DNA Certified
This is undeniably Australia's most popular buffalo variety. The main ID features include a beautiful deep green hue, a broad leaf, and a texture that is notably soft to touch, alongside a very dense low thatch. In winter, it may lose some colour in colder climates, but it bounces back strongly in spring.
It delivers exceptional shade performance. This variety is the go-to benchmark, so if you are unsure what your buffalo variety is, Sir Walter is the most likely candidate in most Australian suburban lawns.
Sapphire Buffalo
If your lawn looks a little different, you might have Sapphire. This type features a finer leaf blade than Sir Walter, meaning it is slightly narrower with a distinct blue-green tint. It remains very soft to touch and produces less thatch over time. It is particularly well-suited for shaded areas with lower foot traffic. If your buffalo looks slightly blue-green and finer than average, it may be Sapphire.
Palmetto Buffalo
Palmetto is highly identifiable by its excellent winter colour in full sun, making it one of the few buffalo varieties that holds its green hue exceptionally well through the cooler months. It features a broad leaf, dense growth, and a notably slow growth rate, which means less time spent mowing on the weekend. If your buffalo stays particularly green through winter in a full-sun yard, Palmetto is a strong candidate.
Matilda Buffalo
Matilda stands out as the fastest-growing of the common buffalo varieties, which means it will produce more thatch and require more frequent mowing, but it compensates by offering the quickest self-repair after heavy use. It holds a vibrant, vivid colour in both summer and winter.
If your buffalo looks vivid year-round and grows faster than expected, it is likely Matilda, which is often chosen for family backyards given its incredible wear tolerance.
What to Do Once You’ve Identified Your Buffalo Lawn
Once you know exactly what you are working with, you can transition into a tailored care routine. There are three key care points specific to buffalo lawns.
First, water deeply but infrequently, because buffalo's drought-tolerant root system prefers long, deep sessions over frequent short sprinkles.
Second, avoid herbicides not labelled safe for buffalo, as this variety is far more sensitive to selective herbicides than kikuyu or couch.
Third, aim to mow at 30–50mm, which is higher than most other common grass types. It is particularly important in summer, when scalping the lawn removes the insulating leaf layer the grass needs in heat.
Since buffalo grass needs precise, infrequent deep watering rather than daily short cycles, automated irrigation scheduling makes a meaningful difference to long-term lawn health. The Aiper IrriSense 2 maps your yard into custom watering zones, auto-adjusts for local weather, and cancels sessions automatically after rainfall — exactly the kind of set-and-forget approach that suits buffalo's watering profile without over-irrigating.
Conclusion
Identifying buffalo grass comes down to three quick checks: a broad, rounded leaf blade, above-ground-only stolons, and strong performance in shade. Once you have confirmed the variety, the right care routine — correct watering depth, buffalo-safe herbicides, and an appropriate mowing height — becomes clear. A well-identified lawn is a well-maintained lawn.
FAQs
How do I know if my lawn is buffalo grass?
Check for broad, flat leaf blades (5–10mm wide) with rounded tips, a soft texture underfoot, and above-ground runners (stolons) only. Buffalo also handles shade well, so if the strip near your fence is still green while other areas brown off, it is a strong indicator. The V-shaped crease when you fold a blade in half confirms it.
Is buffalo grass soft or prickly?
Modern soft-leaf buffalo varieties like Sir Walter and Sapphire are noticeably soft underfoot and non-irritating, making them ideal for children and pets. Older buffalo types could be scratchy, but most varieties available in Australia today have been bred specifically for softness. If your buffalo feels coarse, it may be an older or less common variety.
Can buffalo grass be identified by its runners?
Yes. Buffalo spreads only via above-ground stolons, which are thick, flat stems creeping across the soil surface. Unlike kikuyu and couch, buffalo has no underground rhizomes. If you can pull a runner up cleanly from the soil surface with no underground branching, diving vertically down, it is very likely buffalo.
