Safety & 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[1].
Cultivation Details
Agave andraea is a plant of the semi-arid tropics of western Mexico. It grows in a region where the mean annual temperature is 20 - 24°c, and the mean annual rainfall is 1,000 - 1,200mm[2]. 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[3]. 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. This species, however, occasionally produces a number of new rosettes from suckers or offsets during its lifespan and these new plants will continue to grow after the death of the parent plant. Individual plants take about 7 - 15 years in their native habitat, considerably longer in colder climates, before flowering[4]. Members of this genus are rarely if ever troubled by browsing deer[5].
Propagation
Seed - surface sow in a container in a light position. The seed usually germinates in 1 - 3 months at 15 - 20°c[6, 3]. 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.
