Late Bloomers

In 1879, Michigan scientist William Beal buried 20 glass bottles of seeds underground. Beal wanted to see how long the seeds would be able to sprout.

Beal planned to dig up one bottle every five years. Now scientists are waiting 20 years between digs, to make the experiment last longer. In 2000, the 15th bottle was dug up. The bottle had more than 1,000 seeds. The 121-year-old seedlings were planted. Twenty-five grew into mulleins (MUHL-uhnz), a kind of flower. The next bottle will be dug up in 2020.
