Blooming: Our plant has never produced flowers. The flowers are greenish-yellow and approximately 2 inches (5 cm) long and flower stalks will reach up to 9 feet (2.5 m) in height.
Culture: Agave angustifolia 'Marginata' need full sun to partial shade or very high interior lighting. In the greenhouse, we use a soil mix consisting of equal parts of loam and sand. Plants are very drought tolerant and will thrive even after some neglect. Plants should be watered and allowed to dry thoroughly before watering again. We fertilize only once during the growing season with a balanced fertilizer. When grown as a houseplant, the temperature should never drop below 50° F (10° C). During the winter months, only water enough to keep the leaves from shriveling.
Propagation: Agave angustifolia 'Marginata' is propagated by using suckers, which often are found growing around the base of the plant, or by seed when available.
