Agave oteroi is a striking and robust medium-sized agave known for its distinctive and solitary rosette formation. The plant features a broad, open crown with a few wide leaves, reaching up to 75 cm in diameter, making it a standout addition to any garden or landscape. This agave showcases two distinct forms; the typical form defined by Gentry boasts ghostly white leaves, whereas the variant described by Felipe Otero exhibits a more compact, rounder form with vibrant green leaves. Often sold under names like Agave sp. Sierra Mixteca FO-076 or Agave horrida var. oteroi, this form occasionally produces stunning blue plants, isolated from their green counterparts. Agave oteroi is truly a unique treasure, differing significantly from the typical Agave titanota, and is highly coveted by enthusiasts for its beauty and rarity. Its deep grey-green rosettes, coupled with thick, parchment-colored leaves adorned with large, fearsome spines, make it a spectacular horticultural specimen.
