She is a sometime gardening teacher, television presenter (Gardening From Scratch and Gardening Week for BBC 2) and now author. Her previous books include Gardening in Your Nightie (2000) - revised and updated to become Gardening in Your Pyjamas - and RHS Grow Your Own Flowers (2011). Read More Read Less
