l have always been in horticulture with a love of plants. I spent some time teaching in Kent but most  of my career has been spent in the commercial seed trade, based in the UK and Holland; and travelling extensively through Europe, the Middle East and Africa. I'm a qualified garden designer, and now work with the RHS developing the trials programme and branded awards (AGM).
