Century Plant Agave americana
ABOUT
The Agave americana, commonly known as the century plant, has a dramatic and imposing presence. This plant is easily recognized by its large rosette of fleshy, thick leaves. These leaves are gray-green in color and have a linear-lanceolate shape, being long, pointed and arching gracefully from the base of the plant. The margins of the leaves are often lined with sharp teeth, and a particularly sturdy, pointed tip can be found at the end of each leaf, which can be dangerous if not handled carefully. The texture of the leaves is rugged, with a leathery and tough exterior that makes the plant well-suited for arid environments. When the century plant is mature, it typically sends up an impressive flower stalk that is crowned with clusters of yellow to yellow-green flowers, adding a showy display to its already striking foliage.

WaterThe Century Plant or Agave americana should be watered sparingly as it is drought-tolerant and prefers dry conditions. During the growing season, which is typically from spring to summer, you can water the plant once every two to three weeks with about 1-2 gallons, depending on the size of the plant and the dryness of the soil. In the winter time, reduce watering to once a month or even less, ensuring the soil is almost completely dry before adding more water. Always avoid water-logging as this can lead to root rot.
LightThe Century Plant thrives best in full sun to partial shade conditions. It's ideal to place it in a spot where it receives at least six hours of direct sunlight a day. If planted indoors, a south-facing window would be the best location to ensure it receives ample sunlight. Too little light can impede growth and cause the plant to become leggy.
TemperatureCentury Plants prefer warm temperatures and are hardy in a range from about 30 to 90 degrees Fahrenheit. They can withstand brief periods of colder temperatures down to about 25 degrees Fahrenheit, but prolonged exposure to cold can damage the plant. Ideal temperatures for the Century Plant are between 70 and 80 degrees Fahrenheit where they can thrive and grow.
PruningCentury Plants require minimal pruning. The primary reason for pruning is to remove any dead or damaged leaves to maintain its appearance and health. Pruning can be done at any time of year but is best done in the spring. When pruning, use clean, sharp tools to make precise cuts close to the base of the leaf to prevent potential disease entry.
CleaningAs needed
SoilThe Century Plant thrives in a well-draining cactus or succulent potting mix with added perlite or sand. The soil pH should be slightly acidic to slightly alkaline, ranging from 6.0 to 8.0 for optimal growth.
RepottingCentury Plants are slow-growing and do not need to be repotted often. Repotting should be done every 3 to 5 years or when the plant has outgrown its current pot.
Humidity & MistingCentury Plant prefers low to moderate humidity levels. It is well-suited to arid environments and does not require high humidity to thrive.
Suitable locationsIndoor
Place in bright light, minimal water.
Outdoor

Life cycleAgave americana, commonly known as the century plant, begins its life as a seed, which germinates in well-drained soil and a sunny location, sprouting into a small rosette. The rosette grows slowly and can take anywhere from 8 to 15 years to mature, developing large, fleshy leaves with sharp spines on the edges. During its growth, the plant stores energy in the form of carbohydrates in its large central stem. After many years, the mature agave sends up a tall flower stalk, which can reach up to 20 to 40 feet in height, bearing clusters of yellow to green flowers that attract pollinators such as bees, hummingbirds, and bats. Once flowering is complete, typically within a couple of months, the plant has expended all of its stored energy and dies. The flowering period also facilitates the release of seeds and, often, the production of offsets or "pups" around the base of the plant, which can be detached to grow new plants, continuing the species' lifecycle.
PropogationPropogation time
Spring-Summer
Propogation: The Century Plant, known scientifically as Agave americana, is commonly propagated by the removal of suckers or pups that emerge from the base of the parent plant. These offshoots are typically removed in the spring or early summer when they are about 6 to 12 inches tall, which is the ideal size for establishing new plants. Gardeners will carefully dig around the base of the sucker to avoid damaging its roots and the mother plant. Once removed, the sucker should be allowed to dry for a few days to form a callous over the cut surface; this helps prevent rot when the pup is planted. It should then be planted in a well-draining soil mixture, placed in a location with indirect sunlight, and watered sparingly until roots are established.
