how long will corn plant live?
I have a 20 yr old corn plant. How long will they live for? I have repotted it over the years and it still growing. I have never trimmed it and it still is growing.
Wow! You have done very well. According to Wikepedia, they are native to Africa, and grow up to 49' tall. They're used sometimes for hedges and living fences. I couldn't find any information on lifespan, but considering that all you have to do to start a new plant is to stick a piece of a cane into the ground, I'd say they're pretty close to immortal.
