Agave applanata Lem. ex Jacobi
Flattened agave
Agave applanata is a large monocarpic succulent endemic to south-central Mexico, with main distribution in Puebla, Oaxaca, and Hidalgo. Its name refers to the flattened, horizontally spreading leaves that characterize the species. It is used in the preparation of tepache (a regional fermented beverage) and small-scale artisan mezcal. The plant forms massive rosettes of broad, closely packed leaves with robust dentition, which can exceed 2 m in diameter in mature individuals. Like all species of the genus it is strictly monocarpic and grows actively during the warm season.

Overview
| Category | Classification |
|---|---|
| Family | Asparagaceae |
| Genus | Agave |
| Growth Habit | Massive terrestrial rosette, solitary or with few offsets; slow-growing, monocarpic; leaves spread almost horizontally. |
| Conservation Status | Data Deficient (DD) / Not formally assessed by IUCN at species level. Local pressure from artisan mezcal extraction and agricultural habitat loss. |
| pH Target | 6.5–8.0 |
| Type | Loose volcanic-mineral soil, well-drained |
Origin & Habitat
Morphology
Lanceolate and flattened, 80–150 cm long and 10–18 cm wide, dark green to glaucous, with robust reddish-brown marginal teeth and a conical terminal spine 3–6 cm long.
ecoYellow-green, 7–9 cm, arranged in panicles on a quiote 5–7 m tall; summer flowering; pollinated by nectar-feeding bats (Leptonycteris spp.).
ecoVegetative stem very short and compressed, almost hidden beneath the rosette. The piña (heart) is large, spherical to pyriform, 30–60 cm in diameter, with high fermentable sugar content.
ecoShallow fibrous roots with wide lateral spread; in clay soils it may develop deeper roots in search of drainage. No differentiated storage roots.

Propagation Strategy
Plant in large container or directly in sloped ground to ensure full drainage
Planting in a small pot — roots become compressed and plant does not develop properly
Every 4–5 years in containers. The plant prefers infrequent repotting; do so only in spring.
Single application of slow-release low-nitrogen fertilizer (5-10-10 or 4-8-8 type) at the start of spring. No additional fertilization during the year.
Uses & Applications
Precautions / Toxicity
Fresh leaf sap can cause contact dermatitis in sensitive skin. Calcium oxalates present in leaf tissue are irritating. Terminal spines present physical hazard.

Plant Health
Root rot (Fusarium spp., Phytophthora spp.) — favored by poor-draining substrates or overwatering during cold season
Mealybugs (Dysmicoccus brevipes) — infests leaf bases and roots; produces honeydew that attracts sooty mold fungi
Agave snout weevil (Scyphophorus acupunctatus) — most damaging insect; larvae bore inside the piña; difficult to detect until plant collapse

"Agave applanata has been documented in traditional milpa systems of the Mexican highlands, where it coexists with native maize and nopal as part of the agroforestry system. Its piña can weigh between 20 and 80 kg, making it attractive for Puebla mezcal producers. It is frequently confused with A. mapisaga in the field."
