A pineapple plant flowers only once, and produces one pineapple. Then it dies. But before it dies it also produces offspring.
Suckers are little plantlets that grow between the leaves of the mature pineapple. When the suckers are about 18-in. long, you can break them off and plant them. They will grow and produce another pineapple!
The flower is attractive to bees, butterflies and birds.
