Schaefer. This Is the Sunflower

This Is the Sunflower is a children's book by Lola Schaefer, with art by Donald Crews, published in 2000. It is available at the Internet Archive.

The story is told with long rhyming lines from the start:

But some seeds fall to the ground and are warmed by the sun:

Which leads to more sunflowers: it's a circular tale... that multiplies!

I really like this book: there is not a story exactly, but there is a chain that comes round in a circle, and the artwork is lovely. Plus all those birds!
