I have a large aloe vera plant indoors that is at least 20 years old. Recently it has grown some kind of appendage which is green, about the diameter of a pencil, 40″ long (it’s growing up the window) and has little pink, white and green flowers hanging from it. What is it? Thank you.
I think you answered your own question. They don’t often flower indoors but yours has managed to finally do so. More on Aloe flowers here: https://www.gardeningknowhow.com/houseplants/aloe-vera/flowering-aloe-vera-plants.htm
