Some bamboo waits over a century to flower, then blooms everywhere at once

Certain bamboo species flower only once every 60 to 130 years, and when the moment finally comes, every plant of that species blooms in the same year worldwide, regardless of climate or where it was planted, thousands of miles apart. The mass bloom is usually followed by the death of the parent plants. Scientists still don't fully understand what internal clock keeps every scattered stand in sync.
