Agave Varieties

4. Plant Description and Characteristics

Agave toumeyana var. bella presents a striking contrast between delicacy and resilience. Here’s a breakdown of its key features:

• Size and Growth Habit: This is a petite agave, forming compact rosettes typically reaching only 10-12 inches (25-30 cm) in diameter, and often no more than 6-8 inches (15-20 cm) in height. It grows slowly, making it ideal for container gardening.
• Leaf Characteristics: The leaves are narrow and lanceolate, with a smooth, dark green appearance. The defining characteristic is the prominent, creamy white margin that creates a beautiful, contrasting border. The leaves are relatively soft, with a slightly ridged texture. Young plants exhibit the most symmetrical, butterfly-like rosette shapes. The terminal spine is typically present, slender and sharp, adding a subtle defensive edge.
• Flower Characteristics: Agave toumeyana var. bella is monocarpic, meaning it flowers once and dies after flowering. The flowering stalk is generally tall, reaching up to 6 feet (1.8 meters) or more, producing a branching inflorescence with yellow flowers. These flowers, while not typically a part of its key value, add a bold dash of colour to the plant’s life cycle. After blooming, the plant puts its energy into producing a flower, then seeds, and finally eventually dies.
• Unique Features: Its compact size, distinctive white-margined leaves, and the graceful symmetry of its rosettes make Agave toumeyana var. bella stand out from other agaves. The scale gives it a character that makes it an excellent choice for smaller gardens, rock gardens, or container arrangements.

4. Plant Description and Characteristics:

Agave victoriae reginae huasteca canyon is a slow-growing, stemless rosette-forming succulent. The hallmark of this agave’s appeal is its dense, symmetrical nature. Mature plants, usually reaching up to 0.6 meters (2 feet) in height and 0.9 meters (3 feet) in width, display thick, stiff, and fleshy leaves arranged in a radially symmetrical pattern. These leaves are a captivating dark green canvas, beautifully overlaid with striking white markings along the margins and often in broken patterns across their surfaces. These white lines, not haphazard but rather raised keels, create a mesmerizing visual contrast. Unlike some of its relatives, this variety thankfully boasts only a small and relatively harmless terminal spine. The leaves themselves are typically lanceolate or somewhat triangular. It should be noted that this plant has the unique characteristic of its growth being comparatively slower than many other agaves.

4. Plant Description and Characteristics

Agave toumeyana var. toumeyana, a jewel of the desert, presents a compact, symmetrical form that captivates with its subtle elegance. Reaching a modest height and width of 1 to 2 feet (30-60cm), this agave differentiates itself from its larger cousins. Stiff, lanceolate leaves, gracefully arching outwards, create a dense, rounded rosette, offering a visually appealing architectural element. The leaves exhibit a striking silvery-grey hue, often subtly tinged with blue, adding a layer of coolness to the desert landscape. Bordering each leaf are small, reddish-brown spines, which provide a touch of visual and physical defense. Be mindful of the particularly sharp terminal spine, as it is a strong indicator of the plant’s resilience. While variations exist within the plants, variegation is not a common trait. And, in a dramatic display of nature’s cycle, Agave toumeyana var. toumeyana is monocarpic, flowering only once in its life. From the center of the rosette, a flower stalk will emerge, reaching heights of 5-7 feet (1.5 – 2m), adorned with a branched structure that will produce pale yellow or greenish-yellow tubular flowers, which beckon pollinators to the plant for its grand finale.

4. Plant Description and Characteristics

Agave victoriaereginae subsp. swobodae is a compact, slow-growing agave that forms a perfectly symmetrical rosette. The leaves are a vibrant dark green with eye-catching white markings.

4. Plant Description and Characteristics

Agave triangularis is a medium-sized agave, forming a striking rosette. Its leaves are arguably the most defining feature. They are thick, rigid, and triangular in cross-section giving it its name, appearing deep green to grayish-green, sometimes with a waxy coating (glaucous). The edges can be smooth or have small, fine teeth. A sharp, dark terminal spine caps each leaf. The leaves are arranged spirally, radiating outwards from the center creating a symmetrical shape and give the plant its elegant look. Some plants display beautiful variegation, such as yellow or creamy stripes along the leaf margins.

4. Plant Description and Characteristics

Agave triangularis ‘Subintegra’ offers an arresting aesthetic in the arid garden.

• Size and Growth Habit: This is a medium-sized agave, typically reaching a height of approximately 0.6 meters (2 feet) and a width of up to 0.9 meters (3 feet). Its growth habit is generally solitary, forming a rosette of leaves.
• Leaf Characteristics: The leaves embody distinctive features. They are, as the latin suggests, somewhat triangular in shape. The coloring of the leaves is a bluish-green, with a subtly textured surface, and they can present a slight curvature. The margins are subtly smooth, and in younger plants, occasional small, blunt teeth may be present on the edges. The leaves converge from a central point, creating a symmetrical arrangement. No spines are present; the leaves are unarmed.
• Flower Characteristics: Agave triangularis ‘Subintegra’ is monocarpic, flowering only once in its lifetime. When it does, it produces a tall, imposing flower stalk, reaching heights up to 3 meters (10 feet) or more. The stalk is often branched, bearing clusters of yellowish-green flowers. The timing is generally after a decade or more of growth; the blooming period usually occurs during the summer months, although this varies according to the climate.
• Unique Features: The key distinction of this species lies in its leaf shape, which is a unique arrangement that is between triangular and lanceolate, or spear-shaped. The absence of prominent spines is another distinguishing trait.

4. Plant Description and Characteristics

Agave turneri is a medium-sized agave, forming a solitary rosette – a single basal grouping of leaves – that can reach up to 2 to 3 feet (60-90 cm) in height and width. The leaves are thick and fleshy, typically lanceolate (spear-shaped), often with a slight curve or arch. The leaves are a striking bluish-grey color and often have a waxy coating, which conserves water. One distinguishing characteristic is the rounded and compact nature of its growth, especially the density of the leaf cluster from which new growth will emerge.

5. Uses

Agave univittata has a variety of applications, from the purely ornamental to the surprisingly useful:

• Ornamental Uses: This agave is highly valued in xeriscaping and desert gardens. It is well-suited to rock gardens, container planting, and landscape designs.

4. Plant Description and Characteristics

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.

4. Plant Description and Characteristics

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.
