Title: Taking down a Century Plant blooming stalk from Fair Oaks Branch TX
Answered by: Barbara Medford

QUESTION:

Our century cactus looks like it's in the final stages of blooming and I read on your site that the original plant dies. Can we go ahead and cut down the tall blooms?

ANSWER:

We assume you mean "Century plant" as we don't know anything about a "century cactus."

There are 10 plants with the common name "Century" plant native to North America, of which 7 are native to Texas. None are native, nor even very close to Bexar County, in Central Texas. All are members of the Agave genus and, since your plant may not only be not native to your area, it may even be a hybrid or native to Mexico, which means it is not in our Native Plant Database at all.

We can, however, answer your question without determining which one it is. You are correct, the "mother" plant will die after it has finished blooming, but once the blooms are well past, it is a good idea to take out the bloom stalk, as it can be quite heavy and might fall over on something or someone after it died. The main plant will linger on for a while, but there are probably numerous "pups" that are offshoots of the plant that will grow, mature and eventually will themselves send up blooms. So, if you don't want Century Plants there any more, we suggest you get those "pups" out now, while they are still small enough to be semi-manageable. And you might want to read this previous Mr. Smarty Plants answer on killing a Century Plant.
