Introducing the Smooth Agave Century Plant, also known as Agave desmettiana a beautiful succulent named for the smooth texture of its leaves. It is a striking succulent prized for its graceful arching leaves and low-maintenance nature.

This fast-growing agave adds bold architectural interest to gardens, landscapes, and container displays. It has several other common names such as the dwarf century plant, smooth century plant, and spineless jade agave. 

Hailing from Mexico, its bright green leaves form an incredible rosette that can grow up to a whopping 4 feet in diameter and 3 feet in height.

The Agave desmettiana has small teeth or sharp reddish-brown spines along the edges, adding an eye-catching element to any garden or landscape.

As this century agave matures, it forms clumps and spreads throughout the area in which it grows.

Each rosette of Agave desmettiana will only bloom once in the spring or early summer, typically between the ages of 10 and 15 years.

With side branches that bear terminal clusters of pale yellow flowers, the flowering stalk rises to a height of eight feet from the center of a rosette. After a century plant blooms the rosette dies, but new rosettes can be easily propagated by offsets or suckers from the mother plant base.

When and How to Water Your  Smooth Agave Century Plant

Like all succulents, this plant has unique watering needs that differ from those of other types of agave plants. Overwatering is a common problem with Agave desmettiana, as it can lead to root rot and other issues. 

Water your Smooth Agave Century Plant deeply every 2 to 3 weeks during the growing season, allowing the soil to dry out completely between waterings, and reduce watering to once every 4 to 6 weeks during the cooler dormant months.

In the spring and summer, you may need to water your Agave desmettiana more frequently. Check the soil regularly and adjust your watering schedule based on weather conditions, soil type, and whether the plant is grown in a container or directly in the ground.

In the fall and winter, you can reduce watering to once every few weeks. Cooler temperatures and slower growth mean the plant uses less moisture, so allowing the soil to remain dry for longer periods helps prevent root rot and other issues caused by excess water.

Light Requirements - Where to Place Your Smooth Agave Century Succulent

When growing indoors, place it near a south-facing window where it can receive at least 6 to 8 hours of bright light each day, or use grow lights to supplement natural sunlight and maintain healthy growth.

In addition to sunlight, Agave desmettiana also benefits from good air circulation.

This helps to prevent the buildup of moisture around the century plant, which can lead to fungal infections and other issues.  

When growing outdoors, it requires a lot of sunlight for at least 4-6 hours a day.  Remember, too much direct sunlight can cause the leaves to burn, while too little light can cause the agave plant to become leggy and weak. Ideally, desmettiana agave should be placed in a spot that receives partial to full sun for most of the day.  

Optimal Soil & Fertilizer Needs 

The smooth Agave plants favor very airy, sandy, well-drained soil. Planting them in ordinary soil will result in compacted roots, stunted growth, and, most likely, root rot. Instead, make or buy a well-draining potting mix, or ideally use our specialized succulents potting mix that contains 5 natural substrates and mycorrhizae to promote the development of a strong root system that helps your succulent to thrive. 

When it comes to fertilizing your agave plant, it only needs a small amount of fertilizer applied once a year in spring. A balanced fertilizer with an NPK ratio such as 5-10-5 works well to to support healthy root development and overall growth without encouraging excessive, weak foliage.

Hardiness Zones & More

It prefers temperatures between 65°F to 75°F and is ideal for the plant's growth and health.

Additionally, indoor humidity levels should be moderate, around 40% to 50%, to mimic its natural habitat conditions.

Remember, it is important to protect the plant from frost and freezing temperatures, as prolonged exposure to cold can damage or kill your agave plant. If you live in a colder climate, consider growing your Agave desmettiana as a container plant that can be brought indoors during the winter months.
