Agave geminiflora
(Tagl.) Ker Gawl.
Asparagaceae
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 geminiflora is an evergreen, short-stemmed, succulent plant forming a dense rosette of leaves that can be 70 - 80cm tall and up to 100cm in diameter. The leaves on mature plants can each be 45 - 60cm long and 6 - 8mm wide near the base. After several years of growth, a flowering stem that can be around 4 - 7 metres tall is produced, after which the rosette will die[
].
The plant is harvested from the wild for local use as a fibre.
Agave geminiflora is found in only two to three locations, and there are ongoing declines in its extent of occurrence due to logging. The plant is classified as 'Vulnerable' in the IUCN Red List of Threatened Species(2019)[

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 are found mainly in the arid and semi-arid regions of southwestern N. America, especially in Mexico, extending from the warm temperate zone to the tropics often at moderate elevations. Many species can withstand at least a few degrees of frost, but only in drier regions and where soils are very well-drained.
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[

Most Agave species are monocarpic, individual rosettes living for a number of years without flowering before sending up an often very large flowering stem and then dying after flowering and setting seed.
Individual plants take about 7 - 15 years in their native habitat, considerably longer in colder climates, before flowering[

]. Prick out the seedlings into individual pots of well-drained soil when they are large enough to handle and grow them on in a sunny position until they are at least 10cm tall before planting out.
Offsets and suckers can be potted up at any time they are available.
Bulbils, where produced, are an easy method of propagation. Simply pot them up and plant out at the beginning of a growing season when they are 10cm or more tall.
