The most southern specimen was found in 1981 in the Refuge Islands at a latitude of 68°21'S.
Fastest Growing Plant - Bamboo
Several species of bamboo hold the record for the fastest growing plants in the world. Some have been measured to grow up to 91 cm per day, which comes to an amazing 4 cm per hour!

Hottest Burning Grass - Cenchrus ciliaris (buffelgrass)
Buffelgrass has been recorded as burning up to 871 °C, and indirectly recorded to temperatures of 900 °C. It is very invasive and has been taking over land in the Sonoran Desert.

Highest Living Grass - Poa attenuata
This grass species has been recorded living at 6150 meters at Mount Shukule II (Ladakh, Western Himalayas). It is only 1 of 6 vascular plants that have been seen at this highest of altitudes.

Succulent Grass - Dregeochloa pumila
A peculiar, little known grass from the coastal southern Namib Desert in South Africa and Namibia, is the only known grass with succulent leaves
Barker, N.P. 1990. Dregeochloa in G.E. Gibbs Russsell, L. Watson, M. Koekemoer, L. Smook, N.P. Barker, H.M. Anderson,M.J. Dallwitz (ed. O.A. Leistner). Grasses of southern Africa National Botanical Gardens, Botanical Research Institute, South Africa.
This species lives in active geothermal areas like Yellowstone National Park, and with the help of viral and fungal partners can grow happily at a mind boggling 65°C!
