Landscape Attributes

Saguaro Cactus is a large succulent evergreen plant with a columnar habit of growth. It tends to grow as a solitary entity comprised of a single primary stem, with the occasional spur extending laterally away from the plant. As a type of cactus, it has no true foliage; the body of the plant is wholly comprised of one or more spiny green stems which are prominently ribbed.

Saguaro Cactus is recommended for the following landscape applications;

Planting & Growing

Saguaro Cactus will grow to be about 20 feet tall at maturity, with a spread of 3 feet. It is often either grown as a solitary specimen or permitted to grow into a broader colony as part of a garden composition. It grows at a slow rate, and under ideal conditions can be expected to live to a ripe old age of 200 years or more; think of this as a heritage shrub for future generations!

This plant should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil pH, but grows best in poor soils. It is somewhat tolerant of urban pollution. This species is native to parts of North America.

Saguaro Cactus is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Its large size and upright habit of growth lend it for use as a solitary accent, or in a composition surrounded by smaller plants around the base and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, this plant may be too tender to survive the winter if left outdoors in a container. Contact our experts for more information on how to protect it over the winter months.
