Xanthosoma sagittifolium
 

Xanthosoma, Elephant-Ear, Malanga

Xanthosoma sagittifolium (L.) Schott.

zan-though-SOAM-ah saj-it-ah-FOAL-ee-um

Araceae

 

Explanation of name: Xanthosoma means yellow body, a reference to the stigma (WA1). Sagittifolium means arrowhead-shaped (leaf).

 

Natural range: Tropical America (not Florida)

 

Recognition: Large elephant-ear Aroid easily confused with Alocasia (and perhaps with Colocasia esculenta). Xanthosoma has particularly large, divergent, basal leaf lobes (sometimes overlapping). For a key to the large-leaved Aroids in Palm Beach County, see Colocasia.

 

Landscape uses: Very large-leaved, fast-growing elephant-ear sometimes encountered in protected sites. Not tolerant of wind, cold, or drying. Not recommended due to Florida Exotic Pest Plant Council listing as a Category II invasive exotic. I (G. Rogers) doubt the colorful-leaved cultivars are likely to become established as pests, although more research is needed.

‘Lime Zinger’ has light-colored leaves. For photos of Xanthosoma cultivars, species other than X. sagittifolium, and related aroids, see the AgriStarts website: https://www.agristarts.com/index.cfm/fuseaction/plants.main/typeID/105/index.htm

Additional species of Xanthosoma in Florida cultivation: Xanthosoma atrovirens, X. jacquinii, X. undipes.  All aroids have toxic raphide crystals.
