Scientific name: Echinocactus grusonii
Common name: Golden Barrel Cactus
Echinocactus grusonii, popularly known as the golden barrel cactus is considered rare and endangered in the wild. The population was critically reduced in the 1990s. This cactus grows in volcanic rock on slopes, at altitudes around 1,400 metres (4,600 ft). Growing as a large roughly spherical globe, Echinocactus grusonii may eventually reach over 1 metre (3.3 ft) in height after many years.
There may be up to 35 pronounced ribs in mature plants, though they are not evident in young plants, which may have a knobbly appearance. The sharp spines are long, straight or slightly curved, and various shades of yellow or, occasionally, white.
Younger Golden Barrel plants do not look similar to mature specimens. The generation lifetime is estimated to be 30 years. It is one of the most popular cacti in cultivation and has been considered a personal favourite by garden designers.
