Deep rooted and drought persistent

Megathyrsus maximum

In stockDownload tech sheet

Very popular perennial grass which is very persistent and has increased productivity in areas with summer rainfall. Gatton has a broader longer leaf and better palatability than green panic. Gatton Panic is tolerant to shade. Suited to well drained soils but will perform on other soils with good fertility. Responds quickly after rain. Does not tolerate waterlogging. Sensitive to frost. Coated and treated with Gaucho.

Key attributes

  • More robust than Bambatsi or Petrie
  • Withstands reasonable grazing pressure
  • Summer active where soil moisture is available
  • Quick to respond after the first autumn rains
  • Broad, dark green leaves
  • Grows on heavy soils through to sands

About this variety

Gatton panic is a deep rooted sub-tropical perennial grass, similar to green panic but with broader, darker green leaves, and more robust than either Bambatsi or Petrie.

Its root depth is what makes it drought persistent, and its root distribution is what makes it responsive. The root system is concentrated in the upper layers of the soil, which allows the plant to react quickly to light showers that a deeper rooted grass would not register, while still carrying enough depth to survive dry periods. It is summer active wherever soil moisture is available and is generally quick to respond after the first autumn rains.

Gatton is also efficient in how it stores reserves. More of its surplus carbohydrate accumulates in the upper part of the plant, where stock can eat it, rather than being locked below ground.

It withstands reasonable grazing pressure, and grows on soil types from heavy grey and brown clays through scrub loams to sands, though on lighter country it needs good nutrition to persist.

Planting & grazing notes

It is recommended to graze after 8 to 10 months or when plants are mature, i.e. becoming reproductive. If desired broadcast/sow any additional legumes in the first autumn after grazing then re-introduce livestock to get seed to soil contact. Implement a rotational grazing system. Graze at 25 to 30cm and leave a residue of 12 to 15cm. Do not overgraze over summer. Being a deep rooted plant Gatton can withstand reasonable grazing pressure however should be rotationally grazed to achieve the best production.

FAQs

What deep rooted summer grass can handle dry spells once it's established?

We recommend Gatton Panic Grass. It is a deep-rooted bunch grass that is persistent in dry conditions once established, and it responds quickly after rain. Its roots are concentrated in the upper soil layers, so it makes good use of light showers. It performs best where there is some summer rainfall and needs pH 5 or higher.

Is there a tropical pasture grass that grows under trees or in shade?

Gatton Panic Grass is tolerant of shade, so it is a good choice for paddocks with scattered trees or shelter belts. It has broad, long, dark green leaves and better palatability than green panic. It suits well-drained soils but will perform on other soils with good fertility, and it is summer active wherever soil moisture is available.

How do I get enough plants when establishing panic grass?

We recommend sowing Gatton Panic Grass with other sub-tropical grasses, as it can be hard to get enough plants on its own. Sow 4 to 8 kg/ha of our coated seed in early spring as soils warm, into a fine, firm seedbed. Manage the first summer carefully so enough plants survive into the following year.

Can I grow Gatton Panic on light sandy soil?

Yes, Gatton Panic Grass can be grown on lighter soils, but it needs good soil nutrition to persist there. It is versatile and also grows on heavy grey or brown soils and scrub loams. We suggest a soil test before sowing and a fertiliser plan to maintain fertility. It suits pH 5 or higher and 300mm or more of rain.

Does Gatton Panic cope with frost or wet feet?

Gatton Panic Grass is sensitive to frost, so it is best kept to warmer districts. It is suited to well-drained soils, and our 2026 guide says it does not tolerate waterlogging, although an older catalogue entry lists waterlogging tolerance. If your paddock gets wet, talk to us first. For wetter ground, our Callide Rhodes Grass is a better option.

Which summer grass bounces back quickest after the first autumn rains?

Gatton Panic Grass is quick to respond after the first autumn rains and after light showers, because its roots sit in the upper soil layers. It is summer active where soil moisture is available and stores more of its carbohydrates in the upper part of the plant, where stock can eat them. Rotational grazing gets the best production from it.

How heavily can I graze a panic grass pasture?

Being deep-rooted, Gatton Panic Grass can handle reasonable grazing pressure, but we recommend rotational grazing for the best production. Wait 8 to 10 months after sowing, or until plants are going reproductive, before the first grazing. Then graze from 25 to 30cm down to a residue of 12 to 15cm, and do not overgraze over summer.

Is panic grass safe to graze for horses?

Many tropical grasses, including panic types, can contain oxalates, which can affect calcium uptake in horses grazing them for long periods. For horse paddocks we suggest sowing Gatton Panic Grass as part of a mix rather than on its own, such as our Northern Perennial Pasture Mix. Talk to your vet about mineral supplements, and keep horses off until plants are well anchored.

What grass should I add to a Rhodes grass mix to make it more productive?

We suggest adding Gatton Panic Grass. It is a useful addition to Rhodes grasses in mixtures, establishes more easily than other panic grasses and can give very good first-year production. It is a bunch grass, so it pairs well with stoloniferous Rhodes grasses such as Finecut and Katambora. Sow the mix at 4 to 8 kg/ha in early spring.

Gatton Panic vs Rhodes grass, which suits my paddock better?

Choose Gatton Panic Grass for well-drained soils, shaded areas and places where fast response to summer rain matters. Choose one of our Rhodes grasses for waterlogged, saline or frost-prone paddocks, or where you need ground cover. Gatton is a deep-rooted bunch grass and Rhodes grasses spread by stolons, which is why we often recommend sowing both together.
