When Daphne is diagnosed with Premature Ovarian Insufficiency at the age of nineteen, her sister Christine steps in to help in the only way she knows how: by donating her eggs. For a while, the world seems corrected. But as the years go by – and Daphne sets out on the long road of IVF – the sisters' relationship begins to twist.

Pennyroyal is a heartrending new play by Lucy Roslyn about sisterhood and motherhood, enduring love, and regrets many years in the making. Inspired by Edith Wharton's 1922 novella The Old Maid, it was premiered at the Finborough Theatre, London, in 2022, directed by Josh Roche.
