Lavender's Tree

On her last day at school before moving, Lavender Rose hears a classmate say that he has a Tree of Heaven in his garden, but her family is on the way before she can find out more. A mention of this at her grandparents' house starts a good-natured argument between the old folk, with Grandfather Rose saying that the Bible talks about the Tree of Life, while Grandmother and Rose think it is the Tree of Heaven. Dragging out an old dusty Bible, Grandfather finds the Tree of Life in Genesis, but the others say that doesn't prove that the Tree of Heaven isn't mentioned elsewhere. Grandfather will show them! He will read the whole Bible just to prove them wrong.
