Safety & Hazards

The plant is said to be poisonous to cattle, sheep and goats[1, 2]. 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[3].

Cultivation Details

Growth—

Agave species are found mainly in the arid and semi-arid regions of southwestern N. America, especially in Mexico. Many species can withstand at least a few degrees of frost and will succeed outdoors in warm temperate climates, 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 drought[4]. Agave species are monocarpic, individual plants living for a number of years without flowering then sending up an often very large flowering stem and then dying after flowering and setting seed. This species, however, normally produces many new plants from suckers and offsets during its lifespan and these new plants will continue the life-cycle. Over time, some plants can form extensive clonal colonies by this means[5]. This species produces flowers after three to five years in its native habitat[1]. The outer leaves of the rosette are hard, coarse, and difficult to work for their fibre. Younger, more tender leaves, grow in a tightly formed cluster, or 'cogollo', at the plant's center. It is from this central bud of unopened leaves that the commercially viable fibre (ixtle de lechuguilla) is extracted. The plant's lifespan is contingent upon the time and frequency of the removal of this central cluster. When the plant is approximately 6 years old, the centre bud contains a marketable fibre. If the plant is not harvested this bud will develop into a 2 - 3 metres high flowering stem, and shortly thereafter the plant will die. Conversely, if this bud is removed during the sixth year of growth, and is periodically cut thereafter, the plant may live 15 - 20 years before dying. The time required to regenerate new buds after cutting varies with rainfall conditions. If precipitation occurs in sufficient quantities, a new centre bud can be ready for harvesting in 6 months. During drought periods, regeneration may require as long as 12 months)[6]. Agave lecheguilla reproduces vegetatively, with new suckers developing from the rhizomes of the mother plant. Field studies conducted at experimental stations in northcentral Mexico indicate that the greater the exploitation of the bud, the more rapid the increase in the number of new suckers[6]

Propagation

Seed - surface sow in a light position, mid spring in a warm greenhouse. The seed usually germinates in 1 - 3 months at 15 - 20°c[7, 4]. 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 in the greenhouse until they are at least 15cm tall. Plant out at the beginning of the growing season, and give some protection from the cold for at least their first few winters[PFAF]. Offsets and suckers can be potted up at any time they are available. Keep in a warm greenhouse until they are well established[4]. 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.
