How to Grow Agave americana 'Marginata' (also known as golden-edge agave and golden-edge false pineapple)

Agave is a perennial evergreen herbaceous plant with a short, slightly woody stem. The leaves mostly grow in clusters, are long-elliptical and vary in size; smaller ones are 145-25 cm long and 5-7 cm wide, while larger ones can reach 1 m long, and are thick, smooth and green, with a yellow-white band along the margin and purplish-brown spiny teeth. The flower stem has many transverse stripes, and the flowers are yellow-green and fleshy; there are 6 stamens with T-shaped anthers; the ovary has 3 chambers, and the style is awl-shaped. The capsule is long-elliptical and loculicidal. The seeds are numerous, flat and black. The flowering period is in summer.

Biological characteristics: Agave americana 'Marginata' is a cultivated variety that prefers sunny, fertile, slightly acidic soil rich in organic matter. It is relatively tolerant of drought and poor soil, dislikes waterlogging, and is relatively tolerant of cold, with an optimum growing temperature of 22-30°C. It is commonly propagated by division and sowing. For division, do it in early spring in April when repotting: lift out the mother plant and peel off the suckers beside it to plant separately. For sowing, seeds can only be produced through cross-pollination; after collecting the seeds, sow them in April-May, and they germinate in about 2 weeks. The seedlings grow slowly, but after becoming established they grow rapidly; only plants over 10 years old can flower and set seed. For pot cultivation, a mix of leaf mold and coarse sand is commonly used. Fertilize once a month during the growing season.

In summer, increase watering to keep the leaves emerald green and tender, and provide slight shade during strong sunlight. After autumn begins, agave grows slowly, so watering should be controlled, the soil should be kept dry, fertilizing should be stopped, and soil should be mounded around the base as appropriate.
