Carol Klein is one of the most familiar gardening experts working in the media today, famous for her regular role as a presenter on Gardeners' World since 1998. Her natural, down-to-earth approach has made her a popular and trusted figure amongst the British (gardening) public. Carol originally studied fine art and spent many years teaching art in schools and colleges. She started gardening and running a nursery from her home in Devon, which became internationally renowned. She began exhibiting at RHS shows in 1990 and went on to win multiple gold medals at Chelsea, Hampton Court, Westminster and Malvern.

Her acclaimed TV series include Wild About the Garden, Grow Your Own Veg, Plant Odysseys and Great British Gardens. In 2011, a 6-part series based on a year in her own garden at Glebe Cottage, Life In a Cottage Garden, was shown and accompanied her book of the same title. It has been repeated every year since. It won TV Broadcast of the Year at the Garden Media Guild, as did 'Scent', Grow Your Own Veg, and Great British Gardens. In 2019 the GMG awarded her their Lifetime Achievement Award. Most recently, she has presented Gardening with Carol Klein, Spring Gardening with Carol Klein and Summer Gardening on Channel 5 filmed at Glebe Cottage.

In 2018 the RHS awarded her their highest accolade The Victoria Medal of Honour. In 2023, Carol was named Iconic Horticultural Hero by the RHS.
