Sarah Cook holds a National Plant Collection of Iris (Sir Cedric Morris introductions), planted in a garden in Suffolk.
Sarah was head gardener at Sissinghurst for 14 years. Since then she has sought out and reassembled an amazing collection of the exquisite bearded irises that were bred and painted by Sir Cedric Morris. She was awarded a Gold medal at RHS Chelsea Flower Show in 2015 and again in 2025. Her irises were the centrepiece of the stunning Chelsea garden designed by Sarah Price in 2023. Having nearly disappeared, these irises are now incredibly popular with gardeners across the UK and internationally.
Sarah Cook is looking forward to keeping you up to date with developments in the collection.
