• Agava — The common name of monocotyledonous xerophytic plants within the genus Agave, native to the arid and semi-arid regions of the Americas, particularly Mexico. These plants are structurally characterized by a dense rosette of large, fleshy, rigid leaves, often tipped with sharp spines, and a gigantic, spectacular inflorescence that appears only once at the end of the plant's life cycle, cultivated worldwide for textile fibers, alcoholic beverage production, or as ornamental plants.
• Agave americana — A famous species of succulent and xerophytic plant within the genus Agave, native to Mexico and the United States, but widely naturalized globally, including the Mediterranean basin. Commonly known as the American aloe or century plant due to the misconception that it blooms only once every hundred years, it is distinguished by its impressive size, grayish-green leaves with spiny margins, and a spectacular inflorescence that can reach up to eight meters in height.
• Agave filifera — A small to medium-sized species of succulent plant within the genus Agave, native to the arid regions of central Mexico. It is easily recognized due to its unique morphological feature: its rigid, narrow, dark green leaves display thin, ornamental white threads along the margins, resembling elastic filaments (fibers) that naturally peel off as the leaf matures.
• Agave geminiflora — A unique species of succulent plant within the genus Agave, native to the state of Nayarit, Mexico. This plant is structurally characterized by an extremely dense and symmetrical rosette composed of hundreds of narrow, linear, flexible, and rounded leaves, lacking marginal teeth but often featuring decorative white filaments peeling from the edges. Its specific epithet refers to its spectacular flowering spike, where the flowers appear arranged in twin pairs along the stalk.
• Agave parrasana — A compact and highly ornamental species of succulent plant within the genus Agave, endemic to high mountainous areas in the Parras region, Coahuila state, Mexico. The plant is distinguished by a globose, tight rosette composed of short, wide, obovate leaves of a blue-gray or glaucous color, heavily armed with prominent marginal teeth and a long terminal spine of a contrasting reddish-brown shade, possessing remarkable resistance to low temperatures.
• Ariocarpus retusus — A cactus species endemic to the arid and semi-desert regions of Mexico (genus Ariocarpus), characterized by the absence of spines in adult specimens and the presence of robust, triangular, grayish-green tubercles, often retuse or rounded at the apex. Commonly known as 'living rock', this globose cactus is extremely slow-growing and features a massive taproot, being bio-structurally adapted to survive within the cracks of limestone rocks.
