All About Whale’s Tongue Agave
Agave ovatifolia, a solitary succulent, can reach heights of 3-4 feet and spreads up to 6 feet wide.

It typically takes about a decade for Whale’s Tongue Agave to mature and produce its greenish-white flowers once. After flowering, the rosette dies, but the plant continues its life cycle through bulbils and seeds.
Whale’s Tongue Agave is part of the monocot genus native to arid regions of the Americas. This species, characterized by its toothed leaf margins, gets its name from the combination of “ovatus” for egg and “agauos” meaning ‘illustrious’.
While closely related to Agave ovatifolia, Agave americana, or Century Plant, is a larger rhizomatous variety tolerant to high temperatures and drought, but it requires careful containment to prevent unchecked spreading.
Another relative, Agave attenuata or Foxtail Agave, lacking threatening spines, boasts harmless, gray rosettes and hails from central Mexico, not the northeastern region like Agave ovatifolia.
Lastly, Agave tequilana, or Blue Agave, used in tequila production, grows tall flowering stems of up to 20 feet. Its greenish-white flowers signal the plant’s end as a non-offsetting succulent.

Once fully established, water occasionally – every couple of weeks in summer and monthly in winter, ensuring the soil’s top inch remains dry.
Soil
