After we had been in California 4-5 years, we suddenly saw one of these through the kitchen window, growing up out of the canyon—it had to be 20 feet tall for us to spot it that way. My mom researched and told us it was a century plant. I was a bit terrified of anything that could grow so fast and so big all by itself, totally out of context, but the name comforted me.
