Palmer’s century plant is native to northwestern Mexico, Arizona and New Mexico. Despite the common name, it only has a lifespan between five and twenty-five years. In its final year, it will produce a flower stalk from 4.5m (14 feet) to 9m (27 feet) high. After flowering and during the development of the seeds, the plant begins to senesce. In other words, fruit are produced only once in its lifetime, a botanical phenomenon termed monocarpy.
Agave palmeri is of importance as a food source for migratory bats. In “Following the Nectar Trail“, Dr. Theodore Fleming writes about the relationships between lesser long-nosed bats (Leptonycteris curasoae) and plants in the Cactaceae and Asparagaceae, including Agave palmeri.
