If you’ve ever looked at your lawn and thought “is this Kikuyu or Buffalo?” you’re not alone. In Australia, especially in warm regions like Perth, Kikuyu grass is one of the most common turf types and also one of the most misidentified.
In this guide, we’ll break down how to identify Kikuyu grass, how it compares to Buffalo & other grasses, and the key visual and physical traits you can check in seconds.
What is Kikuyu Grass?
Kikuyu grass (Pennisetum clandestinum) is a fast-growing warm-season turf grass originally from East Africa. In Australia, it’s widely used in residential lawns, sports fields, parks, and high-traffic areas because it’s tough, self-repairing, and extremely fast spreading.
We often see Kikuyu confused with Buffalo or Couch, but once you know what to look for, it becomes very easy to identify.
How to Identify Kikuyu Grass (Quick Answer)
You can identify Kikuyu grass by its:
- Bright, vibrant green colour (lighter than Buffalo, richer than Couch)
- Broad leaf blades (around 4–10 mm wide)
- Fast, aggressive spreading through visible runners (stolons)
- Thick, carpet-like dense growth
- Slightly coarse but soft texture underfoot
- Strong growth in full sun areas
If your lawn is rapidly spreading into garden beds or bare patches, there’s a high chance it’s Kikuyu.
5 Key Visual Features to Help You Identify Kikuyu Grass
1. Leaf Colour and Texture
Kikuyu has a bright apple-green colour that stands out in warm months. Compared to Buffalo grass, it looks lighter and more “fresh green”.
The leaves are:
- Broad and flat
- Slightly coarse but still soft
- Around 4–10 mm wide
- Sometimes slightly shiny under sunlight
At a glance, Kikuyu looks more “wild and energetic” compared to the calmer, darker Buffalo lawn.
2. Growth Habit (Most Important Identifier)
This is the biggest giveaway.
Kikuyu spreads through:
- Above-ground stolons (runners)
- Below-ground rhizomes
These runners are:
- Thick and fleshy
- Light green to whitish
- Clearly visible across soil surface
If you see grass actively crawling and spreading sideways, that’s almost always Kikuyu.
It grows extremely fast in warm seasons and often several centimetres per week in peak conditions.
3. Lawn Density and Feel
Kikuyu forms a:
- Dense carpet-like lawn
- Soft but springy underfoot feel
- Thick mat that fills bare patches quickly
It’s commonly used in:
- Sports fields
- Public parks
- High-traffic backyards
This density is why it feels “bouncy” when you walk on it.
4. Height and Mowing Behaviour
If left unmown, Kikuyu can quickly grow to:
- 10–15 cm or more
You’ll notice:
- Rapid regrowth after mowing
- Need for frequent cutting (often weekly in summer)
- Thick thatch build-up if ignored
This aggressive growth pattern is a major identification clue.
5. Hidden Seed Heads
Kikuyu has a unique flowering trait:
- Small, hidden seed heads inside leaf sheaths
- Fine white filaments sometimes visible (often mistaken for spider webs)
- Not very obvious compared to other grasses
This is why the name clandestinum means “hidden”.
Buffalo vs Kikuyu Grass: How to Tell the Difference
When we look at Buffalo vs how to identify Kikuyu grass, the differences become incredibly obvious once you know what to look for.
Here is the quick comparison guide to tell them apart:
| Feature | Kikuyu Grass | Buffalo Grass |
| Leaf Colour | Bright light green | Darker green |
| Leaf Width | Medium | Broad |
| Growth Pattern | Very aggressive spreading | Controlled growth |
| Runners | Visible stolons and rhizomes | Minimal runners |
| Shade Tolerance | Low | High |
| Maintenance | High | Medium |
| Texture | Coarse to medium | Soft and broad |
Comparing Kikuyu to Other Common Aussie Grasses
To make sure you’re entirely confident in your lawn identification, here is how Kikuyu stacks up against a few other common turf varieties we see around Perth:
- Couch Grass (Bermuda Grass): Couch has a much finer, narrower leaf blade than Kikuyu. While both have underground rhizomes and above-ground stolons, Couch feels softer and more delicate. Couch seed heads look like little helicopter blades or a bird’s foot (a cluster of 2 to 6 spikes) standing tall above the turf.
- Zoysia Grass: Zoysia blades taper to a tip like Kikuyu, but Zoysia is much stiffer to the touch and grows significantly slower. Zoysia is non-invasive compared to Kikuyu’s aggressive sprawl.
- Tall Fescue / Ryegrass (Cool-Season Grasses): These thrive in cooler climates and grow in “clumps” or bunches rather than spreading laterally with runners. If your grass has no creeping runners at all, it’s likely a cool-season variety.
Why Kikuyu Thrives in the Perth Environment
Here in WA, we deal with blistering hot summers, sandy soils, and coastal salt spray (thanks to the Fremantle Doctor). Kikuyu has exceptional environmental adaptability. Its deep rhizome root system makes it highly drought-tolerant, meaning it survives our water restrictions brilliantly. Because it repairs itself so fast, it is the ultimate high-wear resistance grass for backyards with active kids and dogs.
The Turf Man’s Maintenance Tips for Kikuyu
If you’ve identified your grass as Kikuyu, you need to manage it properly so it forms a dense, carpet-like lawn without becoming unruly.
- Frequent Mowing: Because of its vigorous growth habit, I recommend mowing Kikuyu every 1–2 weeks during spring and summer. Keep the mowing height between 30mm and 50mm. Don’t scalp it, or you’ll expose the brown thatch layer underneath.
- Thatch Management: That aggressive growth leads to thatch build-up. I highly suggest scarifying or dethatching your Kikuyu lawn once a year in early spring to allow water and nutrients to penetrate the soil surface.
- Watering: Deep, infrequent watering is the secret. Train those roots to grow deep into Perth’s sandy soil.
- Edge Control: Because of those creeping stolons, you must maintain strict garden edging, or the Kikuyu will happily invade your flower beds.

Frequently Asked Questions (FAQs)
1. What is the easiest way to identify Kikuyu grass?
The easiest way is to check for bright green colour, fast spreading runners, and rapid growth in warm seasons.
2. How is Kikuyu different from Buffalo grass?
Buffalo grass has broader, darker leaves and slower growth. Kikuyu spreads aggressively with visible runners.
3. Is Kikuyu grass invasive?
Yes. Kikuyu is considered invasive due to its fast spreading stolons and rhizomes.
4. Why is Kikuyu grass popular in Australia?
It is popular because it is durable, fast-growing, and highly resistant to foot traffic and heat.
5. What is the best way to stop Kikuyu from spreading into my Buffalo lawn?
If Kikuyu is invading your Buffalo lawn, you have a tough fight ahead because Kikuyu’s underground rhizomes will outcompete Buffalo. You cannot use standard broadleaf weed killers. You will need to carefully paint the Kikuyu leaves with a non-selective herbicide (like Glyphosate) using a brush, being incredibly careful not to touch your Buffalo grass.
