Aechmea magdalenae aka Arghan

Aechmea magdalenae is an evergreen perennial in the bromeliad family. Common names include pingwing, pita, and ixtle. Its native range runs from central Mexico south to Ecuador. Records also include Colombia and Venezuela. It grows in wet tropical forests and thickets. In Guatemala, most records come from below 1,640 feet [500 metres]. Plants can form dense stands beneath the forest canopy.

This large herb grows slowly and has strong spines. Published height accounts range from 3.3–11.5 feet [1–3.5 metres]. Both plant references give about 8.2 feet [2.5 metres] as its usual height. Spread accounts differ, from 4.9–6.6 feet [1.5–2 metres] to 8.2 feet [2.5 metres]. A short, thick stem bears a rosette near ground level. The thick leaves have a waxy surface. They reach about 8.2 feet [2.5 metres] long. Their width is about 0.16–0.33 feet [0.05–0.1 metres]. PFAF describes a ground-growing plant, while Kew lists an epiphytic life form.

The fleshy fruit is oval to egg-shaped. Each fruit measures about 0.16–0.20 feet [0.05–0.06 metres] long. Its width reaches about 0.07 feet [0.02 metres]. Yellow fruits soften and turn orange as they ripen. People eat them fresh or cook them. Their taste combines sweetness with an acid edge. Some accounts favour using the fruit in drinks. The supplied records give no flowering season or flower colour.

For cultivation, PFAF lists deep shade and partial shade. It calls for moist soil with good drainage. Sandy, loamy, and clay soils all fall within its stated range. It also accepts mildly acid, neutral, and mildly alkaline soils. PFAF gives USDA hardiness zones 10–12. Seed is the listed means of propagation. Useful Tropical Plants records occasional ornamental planting in Guatemala City. Its broad rosette and long leaves provide its main described form. The sources give no specific pest or disease problems.

People gather wild plants for their fruit and leaf fibre. The fine, strong fibre serves for rope, twine, and string. Other uses include hammocks and bags. Processing involves soaking the leaves and pounding them in running water. PFAF reports no known medicinal uses. Both plant references list no known hazards. That statement does not establish pet safety, and the strong spines remain a physical hazard.
