Agave
Agave is one of the few succulents that can withstand South Carolina winters, and the Americana variety, or century plant, is often used in landscaping. These cacti can get as large as a VW bug and are very showy when they bloom – only once – and after ten to thirty years of growth.
Most Popular Types
Century plant (Agave americana) – These agave typically flower after a decade of growth. The inflorescence, or flower stalk, can grow to 30 ft.
Queen Victoria – This chunky, rigid agave has spines at the tips and distinct white geometric lines along its thick stems.
Hedgehog Agave – Like a big spiky ball, these are cute as a hedgehog – but not as cuddly.

full sun
Temperatures
The century plant is winter hardy to 22 degrees. Other agaves are less hardy, and we recommend protecting them at temperatures below 40 degrees.
Watering
Outdoor agave do well when taking in water as it rains. Watering 1-2 times per month is sufficient for agave during dry spells or when placed in covered areas.
Toxicity
Agave sap may cause skin irritation, and its spines can cause infection if a fragment remains under the skin. Agave is commonly distilled to make Mexcal such as tequila.
Growth
The Americana agave can grow to a height of 12 ft, with an additional 30 ft of flower stalk. Others, such as the hedgehog agave grow to about 12 inches in diameter.
Most agave are monocarpic. Once it flowers, it will put out lots of pups, and then the main plant will die.
Origin
Mexico and Caribbean
Propagation
Agave grows offsets (pups) which can be cut from the main plant and rooted.
Dormancy
Agave is winter dormant.
