Not sure if it has been posted a long time ago... But today i found on web this book, a spin-off of The Wizard of Oz, written and illustrated by Eric Shanower. In this novel, a witch creates a growth potin than enlarges vegetables in the garden. "Dorothy falls prey to giantism herself and endures a subterranean ordeal before she, the Wizard, and Princess Ozma resolve the problem", as wiki reports.

The most interesting thing is that wiki also says: "Shanower's The Giant Garden of Oz is (both literally and figuratively) a gritty ordeal, with abundant dirt, hunger, thirst, tears, bleeding, and suffering. His image of a filthy, naked, gigantic Dorothy Gale is certainly one of the most striking extremes in the literature of Oz."
We can read a very brief extract of the book here:

Hope for illustrations of the growth sequence too.
