The saguaro cactus [Carnegiea gigantea] may sprout from seed within 2-4 weeks. But it'll take 40+ years for the cactus to sprout branches and flowers. During the first four decades of its life, it concentrates energizing photosynthetic products into such life supporting processes as growth and water intake.
Saguaro is a large, tree-sized cactus species in the monotypic genus Carnegiea.
It can take anywhere from a few weeks to several years for a saguaro seed to sprout, depending on environmental conditions such as temperature and moisture levels. Some seeds may require scarification or soaking to germinate.

Three plants that thrive in deserts are the saguaro cactus, creosote bush, and Joshua tree. The saguaro cactus stores water in its stem to survive long droughts, while the creosote bush has small leaves that minimize water loss and can produce a chemical that inhibits the growth of nearby plants, reducing competition. The Joshua tree has deep roots to access groundwater and a unique structure that allows it to capture moisture from the air. These adaptations enable them to survive in harsh, arid environments.
A saguaro would probably quickly get root rot and die as the soil in Florida is much too moist for a saguaro to remain healthy. They need a fast draining soil that does not remain wet for long after a rain.
Three (3) feet (0.9144 meters) may be how tall a saguaro cactus plant (Carnegiea gigantea) is after 15 years.Specifically, the saguaro is a slow-grower among plants in general and cactus plants in particular. But it makes up in mature height and longevity for what it lacks in speed! For example, its expected life span may reach 100-200 years. Also, its expected mature height may range from 15 - 50 feet (4.52 - 15.24 meters).
That depend upon the species. Some, such as the opuntias (prickly pear, cholla) can go from seed to a sizable plant in just a few short years. Others, such as the saguaro and barrel cacti, can take many decades to grow to a respectable size.
A mature saguaro cactus can store around 200 to 400 gallons of water, depending on its size and age. This impressive capacity allows it to survive in the arid desert environment by absorbing rainwater and storing it in its tissues. The water storage helps the cactus endure long periods of drought common to its native habitat.
The major pollinator of agave and saguaro plants is the bat, specifically the lesser long-nosed bat and the Mexican long-tongued bat. These bats are attracted to the flowers of these plants, which bloom at night, and they play a crucial role in their reproduction by transferring pollen as they feed on nectar. Other pollinators, such as bees and birds, also contribute, but bats are particularly vital for agave and saguaro species.

There are saguaro cacti that live in the desert but there is no Saguaro Desert.
