Over 50 arms may grow on one plant, with one specimen having 78 arms. [6] Saguaros grow from 3–16 m (10–52 ft) tall, and up to 75 cm (30 in) in diameter. They are slow growing, and routinely live 150 to 200 years. They are the largest cactus in the United States. [7] [8] A many armed saguaro in Tucson, AZ. Woman for scale.
An average mature cardon may reach a height of 10 metres (30 ft), but individuals as tall as 18 metres (60 ft) are known. [11] It is a slow-growing plant [12] with a lifespan measured in hundreds of years. One way scientists have aged these cacti has been to use radiocarbon dating to test the spines closest to the ground. [13]
Trichocereus macrogonus var. pachanoi is normally 3–6 m (10–20 ft) tall and has multiple branches, usually extending from the base but will emerge around broken branches. [4] The tallest recorded specimen was 12.2 metres (40 ft) tall. [5] White flowers are produced at the end of the stems; they open at night and last for about two days.
The plant is large, with tree-like growth, and can reach a height of 5 to 8 m up to 12 m. The trunk is thick and short, measuring about 40 cm in diameter, with numerous erect or somewhat bent branches. The blue-green shoots turn greenish-gray with age, are usually not jointed, and have a diameter of 9 to 10 cm.

The ground pressure of motorized vehicles is often compared with the ground pressure of a human foot, which can be 60 – 80 kPa while walking or as much as 13 MPa for a person in spike heels. [ 3 ] Increasing the size of the contact area on the ground (the footprint ) in relation to the weight decreases the unit ground pressure.
The body can range from dull-green or blue-green, almost cylindrical more or less flattened up to 40 cm (16 in) in diameter, up to 90 cm (35 in) tall. Spines can grown to 3–4 cm (1.2–1.6 in) long, colors varies from yellowish-brown, reddish or white becoming grey with time which contrast well against the green body, 1−3 centrals and 10− ...
