Flowers

There are so many different types of flowers. Each flower itsewlf is beautiful in it's own way.

Flowers did not always exist; they first appeared 140 million years ago. Before that, ferns and cone bearing trees dominated the earth.

Several centuries ago in Holland, tulips were more valuable than gold.

Broccoli is actually a flower.

Some plants such as orchids do not need soil to grow-they get all of their nutrients from the air.

Some plants produce toxic substances that kill other plants around them-the sunflower is an example.
