(A form from the locality: Nativitas) This species is highly variable in form, size and colour and many varieties have been described and may be anywhere between 10 and 90 cm in diameter when fully grown up. The smaller form (called Butterfly Agave) are highly prized in Japan Most of them grow very symmetrically, staying smaller in containers.
Origin and Habitat: Mexico, occurs from southern Pueblo state down to central Oaxaca and Chiapas, and is quite variable.
Habitat and ecology: Semi-arid highlands between 1200 and 2250 metres above sea level.

Description: Agave potatorumSN|540]]SN|540]] is a small Agave, growing solitary or slowly clumping, that forms an compact to open symmetrical succulent rosette. It is a very polymorphic species with a large range of variability from which many cultivated varieties have been derived. Rosettes may be anywhere between 10 and 90 cm in diameter when fully grown-up. Leaves may be few or many, variable in colour from green to yellowish green to nearly white glaucous grey or bluish. Generally they are ovate or short lanceolate, but very variable. Altogether, these variations illustrate that A. potatorum is a freely seeding outbreeding complex, that has been widely assorted by circumstances of habitat, changing climates over a long period of time, and man's interventions.
Derivation of specific name: The specific name "potatorum" has nothing to do with potatoes, it comes from the genitive of the Latin word "potator" meaning 'of the drinkers' in reference to the use of this plant in making alcoholic beverages.
Stem: Usually stemless or very short stemmed.
Leaves: 30 to 80 per rosette, softly fleshy but rather rigid, thickened and narrowed toward the base, ovate, oblong, or short lanceolate, but very variable in shape, size and colour. They are mostly 9-18 cm broad and 20-40 cm long and green, blue-grey to light silvery-grey. They are slightly deflexed back near the tips that terminate in a distinctive, often twisted or slightly wavy, reddish, dark brown spine up to 2,5 long. The short marginal spines are often on pronounced tubercle-like prominences often dramatically so, with distinct teats. The teeth are usually rusty or yellowish coloured 0,6 to 1,3 mm long, 0,5 to2,5 cm apart. The leaves also have noticeable showy bud-imprints.
Flowers: The long spikes may by either a raceme or a panicle and rise up to 3 to 6 m bearing light green flowers tinged with red and subtended with red bracts.
Subspecies, varieties, forms and cultivars of plants belonging to the Agave potatorum group
- Agave potatorum Zucc.: Small Agave, growing solitary or slowly clumping, that forms an compact to open symmetrical succulent rosette. It is a very polymorphic species with a large range of variability and the size.
- Agave potatorum f. compacta hort.: Dwarf cultivated form that grows eventually up to 20(-30) cm tall and in diameter. The leaves have distinct showy bud-imprints.
- Agave potatorum Tlaxiaco, Oaxaca, Mexico: This population has very nice bright orange marginal teeth.
- Agave potatorum var. verschaffeltii A.Berger in A.Berger: The old name ''verschaffeltii '' is still in use to distinguish plants with sinuous leaf margins and with teeth atop of outward-projecting bumps.
- Agave potatorum cv. Cubic: The leaves grow as if 2 leaves are fused together resulting in some of them having a 4 angled appearance and forming a square shape. Marginal spines can grow on up to all four of the leaf sides.
- Agave potatorum cv. Kichijokan: Variegated form with amazing symmetrical lotus like leaf pattern. The leaves have lateral, creamy-coloured variegations. Nice imprints are present on the back side of the leaves. The edges have large rusty coloured teeth and are a purplish/maroonish colour.
- Agave potatorum cv. Shoji-Raijin hort.: Also called 'Blue rose' it is tiny rosette of plump blue leaves that stay very small and compact. It produces offsets and forms a small clump of 6-7 cm rosettes. Mature plants stays in 10 cm pots only.
- Agave potatorum cv. Shoji-Raijin variegata marginata hort.: Has a creamy-white or pale-green irregular stripe on the edge of the leaf.
- Agave potatorum cv. Shoji-Raijin variegata mediopicta hort.: Has a broad white band down the centre of each leaf.
Notes: Agave potatorumSN|540]]SN|540]] is included in the group Hiemiflorae. As a general rule, plants in this group have relatively short lateral branches on the inflorescence and tight ball-like clusters of flowers. They typically are winter-flowering, although Agave potatorumSN|540]]SN|540]] is a little earlier than most, with a September-to-December peak flowering time.

Cultivation and Propagation: Agave potatorumSN|27883]]SN|540]] is a relatively easy-to-grow species, though not as cold-hardy as many of the more northerly-occurring species (Winter hardy to around -3° C degrees). Suited for light shade to full sun, but better with some shade in summer. It needs a very well-drained, soil. It grows fairly fast in summer if provided with copious water, but allow to dry thoroughly before watering again (the more water and fertilizer this plant gets, the faster it will grow). During the winter months, one should only water enough to keep the leaves from shrivelling.
It does great in containers or in the ground. Plants cultivated outdoors are more drought tolerant and can take some heat and full sun. Remove eventual suckers to show the beauty and form of the individual rosette.
Uses Agave potatorum is is used in Mexico for making ''pulque'' the Mexican wine. In Sonora (Mexico) the hearts (central part of the rosettes and base of leaves) are placed in subterranean ovens and the resulting fermented juice is distilled to make a a spirit called Bacanora. It is also one of the agave species authorized for the production of mescal, other species commonly used are: Agave marmorataSN|519]]SN|519]], Agave seemanniana, Agave rodacantha and Agave salmianaSN|540]]SN|27883]].
Propagation: By seeds or by suckers that are found growing around the base of the plant, however this species rarely offsets many plants after maturing,. This begins to occur when they are as young as 10 years old. They will flower (usually during the autumn) and the entire plant declines and dies. But many of the clones actually in cultivation are more prolific, and suckers are readily available. The basal suckers can be removed in spring or summer, letting the cuttings dry for a few days before inserting in compost.
