It’s curious that an agave that flowers once at the end of life produces such an enormous bloom stalk. These can range from 5- to 15-feet tall, depending on the species. Many of the flowers are clustered at the very top, which is an adaptation for one particular pollinator, the bat. Because bats use echolocation to guide them, it can be more difficult to navigate their way through brush and thickets. So naturally a plant that seeks these night-flying pollen vectors would raise its flowers above the brush where they are easily accessed by bats. Without bats there would be minimal pollination of these plants, which are the primary source of tequila production.
