Morphological description

A highly variable species, in the P. coloratum - P. stapfianum complex, with types varying in appearance from small and fine to large and robust.  A shortly rhizomatous, tufted (erect, geniculate or decumbent) perennial, sometimes with long spreading stolons.  Stems 2-4 mm in diameter, and culms 0.3-1.5 m tall at maturity.  Foliage mostly 20-70 cm tall, with leaves glabrous to hairy, 5-40 cm long and 4-14 mm wide, varying in colour from green to glaucous blue-green.  Panicle open, erect or nodding, 6-30 cm long, the lower branches mostly single, occasionally paired, rarely whorled;  spikelets green and purple, 2-3 mm long, obtuse or subacute, 0.8-1.4 million seeds/kg.
Var. coloratum, which seldom exceeds 120 cm tall, is the most widely distributed variety, and differs from var. makarikariense in having green leaves, whereas the latter has bluish, glaucous, usually fleshy leaves with strong white midribs.  The Kabulabula type, a robust variety from Botswana and Namibia, often forming a whorl of 2-3 lowermost branches in the inflorescence , is somewhat intermediate between the two varieties, but is usually included in var. coloratum.


Native to:
Africa:  Angola, Botswana, Cameroon, Egypt, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, Sudan, Swaziland, Tanzania, Uganda, Zambia, Zimbabwe.  Var. makarikariense is largely limited to Botswana, where it was originally collected from the Makarikari (now Makgadikgadi) Salt Pans, and adjacent areas.

Cultivated and widely naturalised elsewhere, including northern NSW and Queensland in Australia (var. makarikariense) and Arizona, south Texas and Oklahoma in the USA (var. coloratum).


Mostly used as grazed pasture, but larger types are suitable for cut-and-carry.  Makes good hay and silage.  Stoloniferous types are ideal for erosion control.


Soil requirements

Found on sandy or clay soils in river beds, drainage courses, around pans or in depressions.  Var. coloratum occurs mainly on seasonally waterlogged soils, rarely on heavy clays that are waterlogged for long periods.  Var. makarikariense occurs on seasonally waterlogged or flooded heavy clays, often with significant salinity, suggesting why some types can produce up 50% maximum yield at an EC of 16.4 dS/m.  Salt tolerance varies among genotypes (see 'Klein Verde').  While some types have been collected on low fertility soils, cultivars of both varieties have largely been selected for performance on fertile soils.


Var. coloratum originates in areas with annual rainfall from 600-1,200 mm, and var. makarikariense from about 500-700 mm.  The former is cultivated in areas with rainfall from 500-1,500 (-2,000) mm.  The latter is mostly sown on seasonally wet or flood-prone soils, and on heavy clays in areas receiving 400-1,000 mm.  The species is drought tolerant by virtue of its deep fibrous root system, and its ability to grow on flood plains (where soil moisture is comparatively long-lasting).  Var. makarikariense has a high tolerance of flooding similar to Setaria sphacelata and Paspalum plicatulum .


In the wild, var. coloratum occurs over a wide range of temperature regimes (c. 18-26°C), from 30°N to 33°S, and at elevations from sea level to 2,000 m.  Var. makarikariense occurs around 20°S and 1,000 m asl, an average annual temperature of about 22°C.  It is difficult to generalise with such a diverse species, but some types, at least, start growth earlier in the spring and continue later into the cool season than do many warm season grasses, providing moisture is available.  Frost survival varies with genotype, 'Pollock', 'Burnett' > 'Bambatsi' (at terrestrial temperatures of -10°C), and 'Selection 75' > 'Verde'.


Prefers full sun.

Reproductive development

Flowers through much of the growing season , but most rapidly in long days of 16 h and at day temperatures of 27-30ºC.


Withstands heavy grazing once established, but should be grazed lightly during establishment as it develops more slowly than, for example,  Panicum maximum  and Chloris gayana .


Survives annual burning, although this is not a common practice in most areas where it is grown.


Guidelines for the establishment and management of sown pastures.


Germination should be tested prior to sowing, since high levels of dormancy that can last from 3-6 months in var. coloratum and up to 3 years in var. makarikariense without treatment, are not uncommon.  As with other panicoid species, germination can be improved by removal of glumes.  It can be planted vegetatively and from seed.  Shy-seeding, stoloniferous varieties such as 'Bushman Mine' are normally planted vegetatively, using rooted cuttings, which are planted on a 60-90 x 60 cm spacing.  Seed can be broadcast on the surface or sown in rows using a sowing rate of 2-4 kg/ha.  Although seedlings can emerge from seed placed to 10 cm in lighter soils, it is safer to sow at 1-2 cm.  Row spacings of up to 90 cm apart are used for rain-grown stands and 30-45 cm under irrigation.  Rolling after sowing improves establishment.  Rolling before sowing to compact the seedbed can also be valuable in heavier soils, which have less tendency to crust if rolled prior to broadcasting and lightly covering the seed with harrows.  Panicum coloratum is generally slow to establish, competing relatively poorly with weeds and other pasture species during early growth.  In warmer environments, early or late wet season sowing is therefore preferred, to avoid competition from vigorous mid-season weed growth.  In cooler subtropical environments where early sowings may encounter competition from spring weeds, it is best to sow when there is the greatest probability of experiencing several consecutive days of rainy weather.


Panicum coloratum grows best on fertile soils.  Linear responses to nitrogen applications up to 450 kg/ha have been recorded in some cultivars but not in others.  However, it is generally not as responsive to N as is Chloris gayana .

Compatibility (with other species)

Grows well with legumes and other grasses, but may be selectively grazed if associated with less palatable species such as Setaria incrassata .

Companion species

Grasses:  Chloris gayana , Setaria incrassata , Bothriochloa insculpta .
Legumes:  Clitoria ternatea , Desmanthus spp., Desmodium uncinatum , Macroptilium atropurpureum , Medicago sativa , annual Medicago spp., Neonotonia wightii , Trifolium subterraneum, Vicia villosa subsp. varia (Vicia villosa subsp. dasycarpa).

Pests and diseases

No significant pests or diseases.  Recorded as being susceptible to maize streak monogeminivirus.  A new species of cyst nematode, Heterodera goldeni, has been identified on Panicum coloratum in Egypt.

Ability to spread

Seeding ability and stolon development influence spreading ability in Panicum coloratum .  Stoloniferous types (e.g. 'Burnett', 'Pollock' and 'Bushman Mine') tend to have poor seed-setting ability, and any spread is by virtue of stolons.  Conversely, freely seeding varieties have good colonising and spreading ability (e.g. klein grass ).  'Bambatsi', although a better seeding form of var. makarikariense, is still a relatively poor seeder and does not spread readily in the paddock.

Weed potential


Feeding value

Nutritive value

CP levels vary from 5 (mature) to 19% (fresh, early season) depending on age of regrowth and fertility of the soil, and average IVDMD of 3- and 6-week regrowth about 60%.  CP levels decline on average 4% units, and in vitro digestibility, 13% units, from 4 to 10 weeks.  P levels in 12-week old regrowth commonly range from 0.15-0.2 (av. 0.18)%, Ca from 0.5-1.0 (av. 0.7)%, and Na from 0.2-0.4 (av. 0.27)%.


The species is generally very palatable, although those varieties that exhibit intense flowering are less attractive to livestock.  Its palatability declines as it matures, as with most tropical grasses).


Photosensitization has occurred in sheep, goats, cattle and horses grazing either var. coloratum or var. makarikariense pastures, but the condition is rare.  Saponins in the grass are assumed to be the cause of the formation of crystalloid substances in the biliary system that subsequently obstruct the bile duct and cause secondary photosensitization .  Deaths due to liver failure have been encountered.  Sheep appear to be more vulnerable to this condition, which is mostly brought on under hot humid conditions, than are cattle.  Sheep, particularly lambs, in stressed condition as after shearing or transport, are the most susceptible, particularly if placed on early regrowth following a dry period.  There is also a report of goitre and deformity in lambs born to ewes grazing P. coloratum , ascribed at the time to sub-clinical levels (51 ppm) of HCN in the grass .

Production potential

Dry matter

Yields of 8-23 (commonly about 12) t/ha DM have been recorded from both varieties, depending on genotype, cutting regime, soil fertility and available moisture.

Animal production

No information available.


2n = 18, 36, 54 (standard diploid, tetraploid and hexaploid) - also irregular chromosome complements of 32, 44, and 56.  Five distinct morphological groups based on chromosome number and flowering behaviour have been proposed.  Type A (36 or 45 chromosomes) is var. makarikariense - robust, usually semi-procumbent, stoloniferous, and has blue-green and glaucous leaves with a white midrib.  Type B (2n = 4x = 36) is the Kabulabula form - erect , bright green in colour.  Type C (54 chromosomes) is var. coloratum, with fine stems and green or blue-green leaves.  Type D (36 or 45 chromosomes) is var. coloratum, also with fine stems and green or blue-green leaves, normally with red nodes.  Type E plants (2n = 2x = 18) are small and have very fine stems and leaves, small panicles.  The species is predominantly cross-pollinated, although crossing between var. coloratum and var. makarikariense is limited.  There is some evidence of apomixis in some forms, judging by the uniformity of the line.  Despite the variability of morphological characters, there is very little agronomic variability among accessions of var. makarikariense.  Breeding and selection programs for seed size and reduced dormancy have been undertaken in Texas, USA.

Seed production

Crops are capable of producing 100-180 kg/ha rain-grown, and up to 400 kg/ha irrigated.  However, seed matures unevenly over a long period (well in excess of 15 days) with no peak maturation, and shatters as it matures.  At 100% maturation virtually all the seed has been shed.  Different harvest methods may be adopted to improve efficiency of collection.  Direct heading will yield about 20-25% of the seed;  cutting with a reaper and binder, drying under cover and subsequently threshing, about 40%;  cutting with a reaping hook, drying in the field and threshing, about 50%;  and collecting seed several times by hand shaking about 60% of possible seed yield.  As a generalisation, seed should be harvested at 22-25 days after anthesis to optimise both seed quantity and quality.  Maturation and dehiscence are improved by allowing seed to sweat in windrows or 15-25 cm heaps for two days prior to drying.

Herbicide effects

Tolerant of pre-emergent application of propazine and triasulfuron, and post-emergent propachlor, metolachlor, and triasulfuron, but susceptible to atrazine, ametryne, prometryne, propazine, linuron, pendimethalin, alachlor, metolachlor, propachlor, metsulfuron methyl and imazapic.  Tolerant of post emergent application of propazine, metsulfuron methyl and triasulfuron but not other herbicides.  Susceptible to 2,4-D and dicamba up to 5-leaf stage, but relatively safe in established swards.  Established stands are also tolerant of picloram, but rates should be checked.

Australia (1958)
From Bambatsi Pan on the Manzamnyama or Nata river in Zimbabwe.  An erect, tussocky, shortly rhizomatous, (seldom stoloniferous), dark-seeded form, 1.5-1.8 m tall, distinguished from most other such forms by its superior seed set.  About 95 percent of the population have the erect habit, about 5 percent have the more spreading and stoloniferous habit described for 'Pollock'.  Slow to establish, but tolerates flooding and is the most frost-tolerant cultivar.  Makes no growth during winter but recovers better than  Panicum maximum  cv. Petrie after winter.  Stands waterlogged conditions as well as 'Pollock' and has a reasonable degree of drought tolerance.
Commercial 'Bambatsi' in Australia is derived from a mixture of 'Bambatsi', 'Burnett' and 'Pollock', which with cross-breeding, has produced a variable but tough and resilient cultivar.
(Q 3510)
Australia (1962) From Botswana.  A tussocky, semi- erect type to 1.4 m tall, with greater ability to spread from the lower nodes than 'Bambatsi', being intermediate between 'Bambatsi' and 'Pollock' in stolon development, having about half the population stoloniferous.  Seed is dark like that of 'Bambatsi'.  Some frost tolerance and slow winter growth although new tillers produced if moisture is available.  Seed ripens unevenly and shatters badly.  Not commercially available.
'Pollock' Australia (1961) Institutional accession from South Africa, "Makarikari No. 2 1947, Rietvlei".  Tussock to 1.2 m tall;  more stoloniferous/rhizomatous than 'Bambatsi' and 'Pollock'.  Leaves slightly smaller than those of 'Bambatsi'.  Inflorescence denser than 'Bambatsi'.  In spaced swards, it develops crowns 90-180 cm in diameter, which is useful for soil conservation, particularly in areas subject to waterlogging .  More frost-tolerant than 'Bambatsi' if grazed heavily in the autumn.  Seed ripens unevenly and shatters badly, as in 'Bambatsi', but yield is half that of 'Bambatsi'.  Not commercially available.
