Beschorneria calcicola García-Mend. is a limestone specialist from the Tehuacán-Cuicatlán Valley of Oaxaca — the same biologically extraordinary region that hosts Furcraea longaeva, Furcraea macdougallii and an exceptional diversity of cacti and succulents. Described by García-Mendoza in 1986, this uncommon species is one of the taxonomically more recent additions to the genus Beschorneria and remains very rarely cultivated outside botanical collections.
Taxonomy and nomenclature
Described by Abisaí García-Mendoza in 1986. Family Asparagaceae, subfamily Agavoideae. The epithet calcicola (Latin: “lime-dweller”) refers to the species’ specialisation on calcareous substrates. POWO gives the distribution as Puebla, Oaxaca and Veracruz (Mexico), in the subtropical biome.
Distribution and natural habitat
Limestone cliffs, ravines and canyon walls in the Sierra Madre Oriental and the Tehuacán-Cuicatlán Valley — steep, rocky terrain, often on north-facing or shaded slopes. The calcareous substrate preference is distinctive and should be replicated in cultivation with alkaline, well-drained soil.
Cultivation guide
| Hardiness | −5 to −7 °C / 19–23 °F (estimated; USDA zone 9a) |
| Light | Partial shade to full sun |
| Soil | Calcareous, very well-drained; limestone soils ideal |
| Water | Low to moderate |
| Availability | Very rare; seed available from Mesa Garden (US) |
The montane, limestone-cliff habitat suggests moderate cold tolerance, probably comparable to Beschorneria yuccoides or slightly less. The Hardy Tropicals UK forum reports a grower raising seedlings from Mesa Garden seed, confirming that propagation material is available for determined collectors. The calcareous substrate preference makes this species particularly interesting for Mediterranean gardeners with naturally alkaline, stony soils.
