Arizona, USA – July 2017
In the Sonora Desert, the characteristic column cacti determine the landscape. These cacti, also known as Saguaro, grow very slowly and only thrive in frost-free altitudes. At the age of 10 years they are only about 4 cm high. The first flowers appear after about 40 years and 2.5 m height, the first branches at the age of about 65 years and about 6 m height. They reach heights of about 12 to 15 m and above and are then over 200 years old.
