Title: Seeds of agave attenuata from San Diego CA
Answered by: Barbara Medford
Agave attenuata (foxtail agave) is native to Central Mexico and apparently somewhat rare in its native habitat. The Lady Bird Johnson Wildflower Center, home of Mr. Smarty Plants, is dedicated to the growth, propagation of plants native not only to North America but to the areas in which those plants grow natively.
Since this plant will not be in our Native Plant Database, we will try to find you some articles that can answer your questions.
From Desert Tropicals Fox Tail Agave
The best article we found was from cactus-art-biz on Agave attenuata. This should answer most of your questions, including the fact that, yes, when the stalk has finished blooming, the whole plant will die, but it will leave behind "pups" that can be used for propagation.
Here is another very complete article Introduction to Agaves from Dave's Garden. Scroll down the page and you will find some pictures and discussion of Agave attenuata.
