Barrel cactus
Encyclopedia : B : BA : BAR : Barrel cactus
A Barrel cactus is a type of cactus characterized by being approximately barrel-shaped. Barrel cacti are classified into the two genera Echinocactus and Ferocactus. Their pineapple-shaped fruit can be easily removed and tastes a bit like lemon. It may reach over a meter in height. Its ribs are numerous and pronounced and the spines are long and yellow. Small yellow flowers appear around the crown of the plant only after many years. It is considered easy to grow and relatively fast growing.
A common myth is that The Barrel Cactus is full of water. In truth, it is filled with a slimy alkaline juice that would cause a net loss of water if drunk.
Many people mistakenly believe that the common sight of a tipped over barrel cactus is due to the cactus falling over from water weight. Actually, barrel cacti fall over due to the fact that they grow towards the sun, just like any other plant. Unlike other plants, however, the barrel cactus always grows towards the south (to prevent sunburn) hence the name "compass cactus."
