Furcraea pubescens Tod. is a poorly known Mexican furcraea from the state of Oaxaca, growing in the dry tropical biome. It is one of the least documented species of the genus in cultivation, with virtually no published garden data available. It is included here for completeness and to honestly acknowledge the current state of knowledge — a gap that future botanical fieldwork and garden trials may help to fill.
Taxonomy and nomenclature
Described by Augusto Catara Todaro. Family Asparagaceae, subfamily Agavoideae. POWO accepts the name. The epithet pubescens (Latin for “becoming hairy” or “downy”) presumably refers to a pubescent character on some part of the plant — likely the inflorescence or flower — though the specific morphological basis is not detailed in accessible sources.
Distribution and natural habitat
POWO gives the native range as Mexico, within the seasonally dry tropical biome. García-Mendoza (2011) treated the species within the Flora del Valle de Tehuacán-Cuicatlán account, placing it in the same biologically rich region of Oaxaca and Puebla that is home to Furcraea longaeva and Furcraea macdougallii.
Cultivation guide
| Hardiness | −1 to −3 °C / 27–30 °F (estimated, USDA zone 10a) |
| Light | Full sun (estimated) |
| Soil | Very well-drained (estimated, based on dry tropical habitat) |
| Water | Low (estimated) |
| Documentation level | ★★ — very limited; cold-hardiness estimate based on habitat and genus-wide data |
No published garden trial data could be found for Furcraea pubescens. The cold-hardiness estimate is based on its dry tropical Oaxacan habitat (lower elevation than Furcraea longaeva or Furcraea parmentieri, suggesting less frost tolerance) and by general analogy with other tropical Mexican furcraeas. This species is unlikely to tolerate more than brief, light frost.
If encountered in specialist collections or botanical garden seed exchanges, it should be treated as a frost-tender species requiring protection below 0 °C.
Conservation considerations
As a narrow Mexican endemic of the dry tropical biome in Oaxaca — the same region where Furcraea macdougallii was driven to extinction in the wild by mezcal agave cultivation — Furcraea pubescens may be at conservation risk from the same pressures. No formal IUCN assessment has been conducted.
