The saguaro cactus is the largest cactus in the world that can grow up to 12 metres and sometimes even taller. Currently the 'Champion Saguaro' is 13,8 metres tall. There was a taller one of 23,8 metres, but unfortunately it fell over during a storm in 1986. However, it grows very slowly so you do not have to worry about space problems in your house. The height will be ± 2 metres after 50 years and the first branch might grow after 75 years. The largest specimens are at least 200 years old to have reached such heights. 
The plant grows in the Sonoran desert in the south-west of the United States and in the north-west of Mexico. Nowadays, the Saguaro National Park offers the plants protection, because the population declined significantly in the last century. 
The plant produces white flowers that bloom predominantly at night and are pollinated by bats. Often times, older plants have many signs of damage. Usually caused by lightening strikes and bird nests, but also name carvings from tourists unfortunately damage the plant.  
Overall, it is an impressive species that grows well in a sunny spot indoors.

Zaden oppervlakkig gezaaid in een zand, potgrond, perliet mix (~1:1:1), en afgedekt met huishoud folie. Na 2 weken zijn 3 zaden gekiemd. Daar is het uiteindelijk ook bij gebleven.
