Foxtail Agave: A Unique and Stunning Addition to Your Landscape

The Foxtail Agave, scientifically known as Agave attenuata, is a succulent that can serve as the perfect focal point in your landscape. With its fleshy, green leaves forming a rosette that slightly arches back, resembling a large, open flower, this plant is a sight to behold. Not only is it visually appealing, but it is also easy to care for. In this article, we will provide you with all the basics of Foxtail Agave care. So, let’s dive in and discover the beauty of this unique succulent.

What Makes Agave Attenuata Unique?

While Agave attenuata is already striking with its rosette foliage, what truly sets it apart is the appearance of its magnificent flowers. These showy blooms resemble a long flower spike that curves and drops to the ground, much like the tail of a fox. However, it’s important to note that these flowers only appear once in the plant’s lifespan, which can take anywhere from 10 to 20 years. The flowering occurs exclusively during spring or summer seasons. This makes Agave attenuata a truly unique and gorgeous addition to any tropical landscape, whether indoors or outdoors.

The Stunning Appearance of Agave Attenuata

The Agave attenuata plant possesses a truly unique appearance, especially when its flowers are in bloom. The foliage, while similar to other agave species, becomes even more magnificent when the flowers are present. Let’s delve into the detailed description of the plant’s appearance, starting with the foliage and then moving on to the flowers.


The foliage of Agave attenuata is evergreen, with fleshy leaves that are ovate in shape and soft in texture. As a succulent plant, it has the ability to store water, which gives the leaves a plump appearance. The color of the leaves can range from silver-grey to blue-green or even yellowish-green. When viewed from afar, the foliage forms a whorl pattern that resembles the shape of an open flower. Despite their rigid and pointed appearance, the leaves are surprisingly flexible, making Agave attenuata a plant that is not only visually appealing but also people-friendly.


The flowers of the foxtail agave are truly stunning. If you have been fortunate enough to plant this succulent 10 to 20 years ago, you will be rewarded with a long spike of inflorescence. These flowers can showcase colors of green, white, and yellow. However, it’s important to note that flowering is rare and occurs only once in the plant’s lifetime. The inflorescence appears at the center of the rosette and forms a tall arch that can reach up to 5 to 10 feet in height. The curve of the inflorescence resembles that of a foxtail, hence the name.

Size and Growth

Agave attenuata can reach a size of 2 to 3 feet tall and 3 to 4 feet wide. When planted outdoors, they can grow quite large, so make sure to allocate enough space in your garden. Additionally, these plants produce offshoots at their base, leading to a denser appearance over time. The growth rate of Agave attenuata is slow, like most succulents. If you prefer to keep your plants at a smaller size, consider planting them in pots for indoor setups.

Fragrance: A Pleasant Surprise

While the flowers of Agave attenuata are extravagant in appearance, they do not possess any fragrance. This is good news for those who are sensitive to strong odors, as there won’t be any unpleasant surprises while keeping this plant indoors. However, if you’re looking for a pleasantly scented agave, consider Agave schottii, which produces sweet and fragrant flowers.

Non-Toxicity: A Safe Choice for Humans and Pets

Agave attenuata is considered non-toxic to both humans and pets. While the leaves contain a sap that can have mild poisonous effects if ingested in large quantities, there is no need to be overly concerned. It’s always a good practice to handle the plant with caution and avoid ingestion. Additionally, keep it out of reach of pets to ensure their safety.

Suggested Uses and Care Tips for Agave Attenuata

There are numerous ways to incorporate foxtail agave into your garden design. It can serve as a stunning accent plant in your outdoor landscape, whether in beds, borders, rock gardens, or succulent gardens. You can also plant it in decorative pots indoors to add a touch of greenery to any space. Foxtail agave pairs well with other cacti and succulents, creating a striking visual composition.

When it comes to caring for Agave attenuata, it is a relatively low-maintenance plant. Here are some essential care tips to ensure its well-being:


Agave attenuata prefers bright light and can tolerate full sun exposure. If planting outdoors, make sure to provide it with 5 to 8 hours of direct sunlight. When growing foxtail agave indoors, place it in the brightest location possible. If transitioning from indoors to outdoors, gradually expose the plant to brighter light to avoid stress.


Proper watering is crucial for the health of foxtail agave. It’s important to avoid overwatering, as this plant is sensitive to excessive moisture. Only water the plant when the soil has completely dried out. During hot seasons, this may occur once a week, while during winter, reduce watering to once a month. Foxtail agave has water reservoirs in its foliage, allowing it to withstand drought conditions.

Agave attenuata is not frost-hardy, so it is essential to maintain a temperature above 50°F (10°C) to prevent damage. If cold weather is expected, bring potted foxtail agave indoors to a well-lit area, such as a sunny window or a room with fluorescent lights. Additional insulation may be needed to protect the plant from freezing.

Air Humidity

Agave attenuata can tolerate average humidity levels and even dry conditions. However, it’s best to avoid placing it near kitchens or bathrooms, as these areas tend to have higher humidity. If grouping your plants, keep foxtail agave away from tropical plants that require high humidity.


Foxtail agave thrives in well-draining soil. For potted plants, any cacti and succulent mix will suffice. If planting in the ground, mix sand and grit into the soil to enhance drainage. A good potting mix ensures that the plant is not sitting in water, preventing overwatering issues. Additionally, Agave attenuata prefers a slightly acidic soil with a pH ranging from 6.6 to 6.8.


Foxtail agave is not a heavy feeder and has a slow growth rate. It is best to avoid over-fertilizing, as this can be detrimental to the plant’s health. A once-a-season feeding of diluted, balanced fertilizer is sufficient to provide the necessary nutrients. During winter, when the plant enters a dormant stage, refrain from fertilizing.


Propagating Agave attenuata is relatively simple. The plant produces offshoots at its base, which can be detached and potted separately to grow new plants. If you have the opportunity, you can also collect seeds from the pods during spring or summer and use them to germinate new agave plants. However, it’s important to note that seed collection can be challenging, as Agave attenuata rarely flowers. Therefore, the vegetative method of propagation is more commonly used.


Foxtail agave has a slow growth rate, so re-potting is typically required only once every two years. Shallow pots are recommended, as the plant has a shallow root system. Use a well-draining mix to replace depleted soil, water thoroughly after re-potting, and keep the plant in shade for a few days to avoid stress.


Occasional pruning is necessary to remove dead and brown leaves at the base of the plant, maintaining its beauty. Complete removal of the whole leaf is preferable to cutting off a portion. Pruning is also essential to maintain the plant’s health, as too many offshoots can compete for water and nutrients, hindering growth. Regular removal of offshoots is advised, keeping only the mother plant and a manageable number of offshoots.

Common Problems and Solutions

While foxtail agave is generally low-maintenance, it’s important to be aware of potential problems that may arise. Here are a few common issues and their solutions:


Common pests that may affect Agave attenuata include the snout weevil, soft scale, and cactus longhorn beetle. Regularly check your plant for signs of infestation and manually remove the pests using tweezers. If the infestation is severe, consider using a broad-spectrum insecticide.


Agave attenuata is susceptible to diseases such as anthracnose, root and crown rot, and Phyllosticta pad spot. These diseases are usually caused by fungi and thrive in consistently damp conditions. To prevent such diseases, avoid overwatering and ensure proper drainage.
