This species have a good number of cacti and many varieties of it. They are found in the West Indies and between north South America to southern Argentina. Due to their location, Cereus tolerates large amounts of the sun and the needless to say, the heat. The shape and size is anywhere from being a small shrubby bushes to tall columnar types and the colours go from green to powder blue. The prominent ribs can be between four and nine with their areoles apart from each other. When the cactus is large it is likely to have nocturnal flowers, which are scented. Needless to say, mine are not big enough therefore no flowers. The Latin word Cereus is translated to wax candle.
This Cereus peruvianus monstrose is fast growing and in the right conditions can grow 12" per year, which ends at about 10' high. It can deal with brief periods of frost, but if the temperature drops to below -4° Centigrade (c. 25° Fahrenheit), it will be damaged. The other main cause for damage and often death, is over-watering, which I am afraid to say that I have been guilty.
A good friend, Doug from Canberra, spoke to his parents and they said this was in the Cereus genus. I did not get the species name, but they said that these cacti are used as root stocks in grafting.
