2．You can't look at sunflowers and feel sad．Their big bright faces almost seem to be smiling at you on a summer day as they slowly turn toward the sun．Not only do the flowers make people happy，they also provide food for bees，birds and squirrels and many other small animals that love to eat the seeds （種子）．
Sunflower seeds aren't only delicious to animals．People love them，too．You can find bags of them in the stores．They tell you what kind of seeds they are and how they should be planted．
There are hundreds of different kinds of sunflowers．The biggest ones are Mammoth Russians．They grow to over 10 feet tall and produce big round heads with bright yellow petals （花瓣）that are over a foot across．They grow on strong thick stems （莖）with big heart-shaped leaves．The ripe seed heads sometimes get so heavy that they hang down．Other kinds of sunflowers，called dwarf，produce small stems and smaller flowers in colors such as light yellow and deep bright orange or red．
Sunflower is also a place in America．People there love sunflowers so much，so they named their place"Sunflower"．There are sunflowers everywhere．
