I've never known anyone who has a pineapple tree. There is a pear tree at my apartment complex. My mom has a pear tree and blueberry trees. She used to have pecan trees. My mother-in-law has persimmon trees and grows peppers and stuff. My brother started a garden at my mom's house earlier this year and is growing all kinds of stuff. I thought about starting to grow whatever I can on my patio.
