We Get Yucca Questions
Q: We planted this cactus over 10 years ago, and the other day were surprised to see a stalk growing out of it. Do you know what types of cactus this is? And is it likely to ever do this again? We live in San Carlos. I would be interested in getting another one.
Your “cactus” is actually a Yucca, most likely Yucca whipplei (a wonderful California native) or perhaps Yucca rostrata. They look very similar and there is not enough detail in you photos for me to be sure… however my guess is yours is Yucca whipplei. If it is, this bloom will be it’s last, as the rosette that blooms dies after it is done blooming and hopefully setting seed (like it’s relatives Agave’s).
It will sometimes “pup” around the base and those will grow in to replace the “mother” rosette, but not always. If it is Yucca rostrata, it will not die, but will grow several new rosettes and eventually become a multibranched tree yucca and will bloom again when it has enough energy stored up to do so. Either way yours is a great looking plant and congratulations in getting it to bloom! It should bloom over the next few months and will look spectacular!
