Can a 25‑Year‑Old Indoor Yucca Survive Outdoors?

If it's the common houseplant yucca (Yucca elephantipes) with shiny, strap‑like leaves and no flowers, it's not cold‑hardy—keep it indoors. If it's a hardy, clump‑forming species (Yucca filamentosa etc.) with long, narrow leaves, it might survive outdoors but after 25 years inside, transition shock could kill it. Consider donating to a public atrium.
