Joe is a boy just like any other, but Joe loves to imagine. Joe lives in a pretty ordinary tower block, in a rather ordinary city. His world is rather grey. However, he spends his time imagining a wonderful world filled with exotic plants and unusual animals. Once day Joe decides to plant a seed on his balcony, he waits and waits but nothing happens! Joe gives up and goes back to his daily life, but one day when he least expects it he spots that the seed has turned into the most beautiful tree. Joe begins caring for the tree and growing lots of other plants on his balcony and soon everyone in the neighbourhood is getting involved. A charming story about the important of nature, teaching us that if we work hard enough our dreams really can come true!
