succulent plant native to Mexico; produces a large rosette of succulent leaves, up to 60-80 cm high and even 100-150 cm wide; the leaves are elongated, rigid and fleshy, very thick, of a bluish green color, covered with a pruinose patina; the margin is sprinkled by short black spines, very sharp. The leaves are erect as soon as they sprout, they bend high, becoming arched at times. From the center of the rosette a tall trunk is produced which bears a showy panicle of bell-shaped flowers, white, very fragrant. It is used as an ornamental plant, even in pots, but more often in rocky or Mediterranean gardens.
it needs to be placed in a very sunny place; during the hot season it can withstand short periods in partial shade; it does not fear frost, and can withstand brief frosts of slight entity, provided the soil and climate are not excessively wet.
from October to March, avoid watering, and place the plant in a place where it does not receive excessive rain; during the vegetative period water sporadically, only in case of periods of prolonged drought. Specimens grown in a container are watered from March to September, only when the soil has been dry for a few days.
like most cacti and succulents, this agave also prefers dry and very well drained soils, not excessively rich in nitrogen; in spring provide a small dose of slow release granular fertilizer, poor in nitrogen and rich in potassium.
this species of agave produces single rosettes, it is difficult to branch into lateral rosettes, and it is therefore difficult to be able to propagate the plant by removing the side rosettes; sometimes from the roots some small new plants can be produced, which can be removed and rooted individually in a container, before being planted. More often it propagates by seed, using fresh seeds in spring.
