The genus Agave is treated here in a wide sense to include taxa previously treated as belonging to the genera Manfreda, Prochnyanthes, Polianthes and Pseudobravoa. Not all botanists are happy with this treatment, with some feeling that these genera should remain distinct, at least until further studies have been carried out. In addition, given the high species diversity found in Agave, some feel that an alternative approach could be the recognition of several smaller genera within the current circumscription of Agave[].

General Information

Agave petskinil is a freely suckering, herbaceous perennial, producing clusters of stemless rosettes from a thick, succulent rootstock. Around 7 - 30 leaves are produced on mature rosettes, with individual leaves around 18 - 38cm long and 1 - 2cm wide. The flowering stems can be 130 - 160cm tall, often producing bulbils as well as flowers. The plant is semi-evergreen, with most leaves dying in the dry season[, ].
The plant is harvested from the wild for local use as a medicine. The species has an unrealized horticultural potential because of its handsome foliage and ease of growth under tropical conditions or in greenhouses in the temperate zone[]..

Known Hazards

Many Agave species have strong, sharp spines on the leaves and leaf tips.
In theory at least, the flowers, nectar, immature flowering stem and the centre of the rosette of all Agave species is edible and, with proper preparation, can provide a sweet, tasty foodstuff. Some species, however, contain relatively high levels of saponins (which makes them taste bitter) and some other compounds which can cause bellyache, and so these would only be eaten in times of desperation. In addition, many people may find these foods to be strongly laxative the first few times they eat them[].

Cultivation Details

Agave species generally require a sunny position, succeeding in most soils of medium-fertility so long as they are very well-drained. Most species are undemanding as to the soil pH, though those found in the wild on limestone soils will grow better in neutral to alkaline conditions. Plants are generally very tolerant of dry conditions and of extended periods of drought[]. The leaves become conspicuously blotched and tinged upon exposure to strong sunlight[].
Whilst most Agave species are monocarpic, the rosettes of this species form a new main stem after flowering and this continues to grow and flower in later years. This species also usually produces new lateral rosettes, eventually developing into large clumps under favorable growing conditions[].
This species is fairly tolerant of damge from fires, usually regrowing from the roots if the top is killed off[].

Edible Uses

None known

Medicinal

The fresh leaves are used in the treatment of strong, permanent headaches by placing them over the forehead[, ]. They are also used to treat headlice[].

Other Uses

Many species of plants formerly recognized as Manfreda, and now included in Agave (sensu lato) have large succulent roots that are rich in saponins and are used traditionally as a soap and shampoo[, ]. We have no specific indormation for this species, but it is likely to have been used in that way[].

A superior fibre is possibly obtained from this species[].
