Agave Varieties

4. Plant Description and Characteristics

Agave mapisaga is a stunning, symmetrical agave, and it’s a medium-sized plant that can take decades to reach its mature forms. Here’s a detailed look at its physical characteristics: Size and Growth Habit: Mature plants typically reach a height of 0.6 to 1.2 meters (2 to 4 feet) and can spread up to 1.8 meters (6 feet) wide. It forms a dense, compact rosette. The Agave develops slowly, and is generally long-lived. The leaves are gray-green to bluish-green, thick, fleshy, and broadly lanceolate. They are often slightly concave. Leaf margins are toothed, with reddish-brown or dark brown spines, which are generally not as pronounced as some other agave species. There is a prominent terminal spine. The form of the plant resembles a large, rounded shape. Flower Characteristics: Agave mapisaga is monocarpic, meaning it flowers only once in its lifetime, typically after several decades. The flower stalk, a tall, erect inflorescence, can reach 3-5 meters (10-16 feet) in height, producing a panicle of yellow or greenish flowers. After flowering and seed production, the plant dies. A unique characteristic is the form of the plant being wider than high. While many agaves become quite tall, this is a more horizontal shape, and creates a significant presence in a landscape.

• Leaf Characteristics: The leaves are broad, lanceolate to ovate in shape and typically green to gray-green in color. They exhibit an exceptionally striking pattern of variegation. Irregular, intricate, often cream or yellow-colored, marble-like markings cover the upper surface of the leaves, giving the plant its ‘marmorata’ name. The margins are typically armed with sharp, reddish-brown spines, which can become gray with age. A prominent, terminal spine crowns the leaf tip. The leaves fan outward from a central core in an upwardly arching fashion, adding to the plant’s sculptural appeal.

Agave mckelveyana is a perennial succulent, growing in a symmetrical rosette shape. This plant is a beautiful demonstration of resilience and natural charm.

4. Plant Description and Characteristics

Agave megalodonta is a moderately sized, solitary agave, typically reaching about 1-1.5 meters (3-5 feet) in height and width at maturity, though the plants can sometimes grow larger. Its growth habit is generally symmetrical, forming a rounded, rosette-like structure. The most striking feature is its thick, lanceolate leaves, characterized by a grey-green hue and a glaucous bloom, appearing a bit blueish. However, the defining characteristic that gives this agave its name is the prominent, large, sharp, brown teeth (megalodonta) edging each leaf, a clear defense strategy in its native habitat. Adding to the plant’s formidable presence is a stout terminal spine at the leaf tip. Like other agaves, Agave megalodonta is monocarpic, meaning it flowers only once at the end of its life, sending up a tall, branching flowering stalk that can reach 4-6 meters (13-20 feet) bearing yellow flowers. After flowering, the plant then dies, but leaves behind seeds and often numerous offsets, ensuring its propagation. The flowers provide crucial nectar for local pollinators.

4. Plant Description and Characteristics

Agave mitis var. albidior is a relatively small to medium-sized succulent, typically forming a rosette of leaves. The most striking feature of the Small Tooth Agave is its pale, almost ethereal leaf color, setting it apart from other Agave varieties. This plant often features a color that varies between a creamy-green or grayish-green to a nearly pure creamy white, especially when young and during cooler temperatures. The plant’s manageable size and graceful form, along with its defining pale color, make it a desirable choice for smaller gardens or container growing, where it adds a touch of understated elegance. The leaves are lanceolate (lance-shaped) to slightly ovate, tapering to a sharp point. The margins (leaf edges) are typically lined with small, reddish teeth, which give the plant its common name, "Small Tooth Agave." A reddish blush often develops on the tips and margins when exposed to direct sunlight or in cooler temperatures.

Agave mitis var. mitis is a relatively compact beauty, thriving in both borders and containers, reaching approximately 1-2 feet (30-60 cm) in height and spreading 2-3 feet (60-90 cm). Its defining characteristic is the rosette which is its smooth, spineless, and fleshy leaves. These lanceolate leaves gracefully curve outwards. They start as a deep, rich green, and can develop reddish hues with sun exposure. Varieties with variegation also exist, enhancing their visual appeal. Unlike many of its spiky cousins, these leaves are usually smooth, a testament and unique feature of the plant itself.

The Agave montana is a visually striking succulent that forms a relatively symmetrical, often solitary rosette. Its allure stems from its bold presence and noteworthy textural features. The mature leaves are thick, fleshy, and generally broad, with an ovate to lanceloate shape, presenting an attractive, vibrant green or bluish-green hue often accented by reddish or purplish margins. These margins are typically smooth initially, but can become fibrous with age, adding further textural interest. The absence of spines along the margins, beyond the sharp terminal spine, showcases a gentler appearance compared to some of its more heavily armed counterparts. While unique markings do not typically decorate the surface, it can be found to take on hints of the surrounding minerals and substrates where it grows. Its remarkable cold hardiness, paired with its architectural form and lack of marginal spines, distinguishes it from many other agave species, making it both a robust and visually appealing species.

Agave havardiana is a stunning, slow-growing, monocarpic plant, that typically creates a rosette of upright architectural leaves.

* **Size and Growth Habit:** Mature plants typically reach 3-5 feet (0.9-1.5 meters) in height and 3-5 feet in width. It is a relatively compact, symmetrical agave. It grows very slowly, taking up to 20 years to flower, and frequently much longer. They are monocarpic, meaning the agave dies after flowering.
* **Leaf Characteristics:** The leaves are thick, rigid, and a striking bluish-gray or blue-green in color. They have a characteristic lanceolate (lance-shaped) form, gradually narrowing to a sharp, reddish to brown terminal spine that tapers out to roughly 1.5 inches (3.8 cm) long. The leaf margins are armed with distinctive reddish-brown or black spiny teeth along the edges, which are often very sharp. The older the plant gets, the deeper the color.
* **Flower Characteristics:** After many years, when it is ready, *Agave havardiana* produces a towering flower stalk, or inflorescence, reaching up to 15-20 feet (4.6-6 meters) in height. The stalk is a central spike with lateral branches. The flowers that bloom are typically yellow or yellowish-green, tubular, and arranged in clusters on the multiple branches, providing a rich display. As a monocarpic plant, *Agave havardiana* dies after the plant flowers, but not until it has seeded generously.
* **Unique Features:** The overall symmetry, the striking leaf color, pronounced leaf teeth, and a relatively compact shape, all combine to make this a very attractive species.
