Title: Can I save my century plant by cutting the flowering stalk in Austin, TX? Probably not.
Answered by: Jimmy Mills

QUESTION:

Our century plant is starting to sprout it's flower (four feet). If we cut it down can we save the plant? Thank you.

ANSWER:

The Century Plant Agave americana (American century plant) is a spectacular plant, and part of that spectacle occurs when it flowers. Now it doesn't take it one hundred years to flower, but to some folks it seems that way. The plant has a monocarpic or semelparous life cycle which means that it will flower only one time and then die.

From the reading that I have done, removing the flowering stalk will not keep the plant from dying. Flowering is controlled by changes in hormonal levels that affect the allocation of resources inside the plant that eventually lead to its demise.  A lot of energy and resources are expended by the plant in producing the flowering stalk and the flowers.

If you wish, you can remove the stalk and see what happens. I think it would be more fun to watch the flowering proceed; maybe make a photo log.

The plant should be producing pups which can be used to propagate new plants .
