Movie S1.

How to grow a snapdragon flower from a cylindrical sheet. Movie shows an example of acomplex vegetable shape. In each case, once the growth patterns are determined by solving the inverse problem, we calculate a sequence of elastic equilibria thatinterpolate between the featureless sheet (the reference state) and the final complex shape.
