And during summer vacation (spent with the teacher's dad), he gets his chance. With the help of a friendly rabbit, Herky prepares the soil, carefully plants pumpkin seeds, and waits. And waits, and waits. One of the most important things he learns about gardening is patience. It's very hard to go back to school when fall comes--especially because his pumpkins aren't quite ready yet. But in October, the teacher's dad arrives with a big pumpkin for her class--that just mysteriously grew in his yard! And Herky begins dreaming about next year's garden . . .

Kate Duke has created a funny and charming book that shows not just how seeds grow into plants, but also how you need patience to see a long project through.
