Agave Varieties

Agave sp. ‘Tunja’ presents an impressive aesthetic with its compact growth habit. This majestic succulent is a study in contrasts, a testament to the beauty found in resilience. The plant forms a dense rosette, typically reaching 2-3 feet (60-90 cms) in height and 3-4 feet (90-120 cm) in width at maturity. A very striking, unique variety is a cultivar with a slight variegation of yellow or cream, and can even be tri-color in certain conditions, catching the eye with its colorful leaves. The leaf margins are adorned with small, reddish-brown teeth (denticles) and a sharp, terminal brown spine. One of the most notable characteristics is the tendency for the leaves to curl inwards, which gives the rosette a textured appearance. This natural ‘cresting’ effect is a particularly attractive feature. At the time of reproduction, the flower stalk can sometimes reach the towering height of 20 to 30 feet (6 to 9 meters), and the flowers are usually yellow/green in color. However, the flowers only appear once in its life cycle.

Agave ssp. ‘Mix’ showcases a striking rosette form, though size can vary depending on parentage and growing conditions. Mature plants generally reach a height and width of 2-4 feet, while some varietals may become much taller over time. The overall shape is a symmetrical rosette of thick, fleshy leaves that radiate outwards. The most appealing feature of Agave ssp. ‘Mix’ is its diverse leaf colors and patterns. While base colors feature shades of green or blue-green, they often display striking variegation, with streaks of yellow, white, or creamy hues along the leaf margins or throughout the entire leaf surface. Leaves are generally lanceolate (lance-shaped) with a smooth to slightly textured surface. Margin types vary, some having smooth margins, while others possess small, sharp teeth or spines. The leaves terminate in a sharp, terminal spine that acts as a form of protection. Though flowering is not guaranteed in any lifetime, if flowers do bud, they grow from a massive flower stalk, reaching 10-20 feet tall.

Agave striata subsp. falcata, a clumping, perennial succulent, distinguishes itself through a series of unique features that make it a favorite for ornamental purposes. Its size and growth habit are relatively compact, typically reaching up to 1.2 meters (4 feet) in height and spreading to a similar width, developing dense clumps through the formation of multiple rosettes. Most notably its foliage is characterized by linear, lance-shaped leaves, up to 1 meter (3 feet) long, and a mere 1-2 cm (.39-.79 in) wide. The leaves showcase a striking color palette, ranging from a deep green to gray-green, set off by a subtly ribbed texture, accentuating the elegant arch of the plant leaves over the central stem. While the edges of the leaves are smooth, the needle-sharp tips require caution when handling. When in bloom, which is a rare occurrence, the plant’s monocarpic nature becomes evident, producing a tall branched inflorescence that can reach up to 3 meters (10 feet) or more, adding to the already impressive features.

Agave striata subsp. falcata ‘Blue’ is a clumping agave known for its exceptionally fine, thread-like leaves. The mature plant creates a dense, rounded clump that can reach a height and width of about 1 to 1.5 feet (30 to 45 cm). The leaves are slender, almost grass-like, and grow upright from a central rosette, creating a fountain-like effect. The most defining characteristic is its blue-gray color with some even displaying a glaucous (waxy) coating. Leaves are lanceolate shaped, and are smooth with no teeth or spines along the margins, making it less dangerous to handle than other agaves. In ideal growing conditions, and after many years, the plant can flower with a tall, branching inflorescence – perhaps as high as 6ft (1.8m), bearing pale yellow or greenish-yellow flowers in late spring or early summer. The plant is monocarpic, so it will die shortly after blooming, after which it produces offsets or bulbils to continue its lifecycle. A unique feature is the delicate appearance compared to other more robust agave species, lending a touch of elegance to any landscape.

4. Plant Description and Characteristics

Agave striata subsp. striata is a striking succulent known for its unique form and textural appeal. The defining characteristic of this agave lies in its foliage. Unlike the broad, fleshy leaves common to so many other agaves, Agave striata subsp. striata boasts long, slender leaves that evoke the appearance of threads or needles. These leaves emerge from a central point but arch outward and upward, contributing to a dense, almost spherical, clump as the plant matures. The leaves are typically a dark green color, often with a bluish or grayish hue, sometimes with a slight sheen, and the texture presents a ribbed or grooved appearance due to prominent longitudinal lines. In the landscape, the clustering habit of these plants creates a visual impact that is difficult to ignore.

Common Names and Etymology

Agave schidigera, primarily known by its scientific nomenclature, also answers to a few nicknames. Perhaps most notably, it is known as the "black-toothed agave" in reference to the dark spines along its leaf margins. Locally, name variations also come into play, reflecting the plant’s distribution across various regions of Mexico. The genus name "Agave" finds its roots in the Greek "agavos," evoking a sense of "noble" or "admirable," likely in recognition of the plant’s impressive form. The specific epithet, "schidigera," is more intricate, with varying interpretations. Some sources suggest it is derived from the Latin word "schisti" meaning "split, divided" and "gerere" meaning "to bear, to carry" and thus refers to the threadlike fibers which are produced on the edges of the leaves; another thought is that is derived from the German name for "shield-bearer" (Schildträger/in), which accurately depicts the prominent ‘teeth’ on the edges of the leaves.

Origin and Natural Habitat

Agave stricta is endemic to the island of Madagascar, specifically the southwestern region of the island. Here, it thrives in dry, rocky habitats, often clinging to cliffs, rocky outcrops, and sparsely vegetated areas. The plant’s natural environment is characterized by the following features.

Agave polianthiflora distinguishes itself through its compact and orderly growth habit.

4. Plant Description and Characteristics

Agave potatorum is famed for its attractive, compact and architectural silhouette. Its leaves are thick, fleshy, broad, and broadly ovate. They are typically grey-green to bluish-green in colour, often with a powdery "bloom" coating. But it is the leaf margins that give it true distinction. They are usually adorned with small, sharp, reddish-brown teeth or spines that are very evenly spaced; the spines along the tips being particularly pronounced. Some cultivars exhibit attractive variegation, adding to their ornamental value, making this agave both visually striking and easy to incorporate into various design concepts.
