Do Pineapples Grow Underground?
Looking at a pineapple fruit, you may notice a leafy, plantlike crown atop a plump, bulbous fruit. The bulbous fruit does not develop underground, but rather at the tip of a sturdy stalk. The pineapple (Ananas comosus) hails from tropical Northern South America and is a bromeliad — a frost-tender perennial that grows with a rosette of sharp leaves that dies after it produces its fruit. Even though the central rosette dies, the root crown produces basal shoots to replace it year after year.
