After working for a time at the drama department of the BBC, Clarke found employment at a herb nursery in Somerset. She married Ian "Mac" McVicar in 1976, and in 1987, they established a herb farm—now known as Jekka's Herb Farm—at Alveston, near Bristol. They have the largest collection of culinary herbs in the UK, with more than 500 different varieties.[3]
McVicar has published several successful books, notably Jekka's Complete Herb Book and Seeds, which have been reprinted in association with the Royal Horticultural Society. She also regularly contributes to a number of national publications, including BBC Gardener's World Magazine, BBC Good Food, Gardens Illustrated, and The Guardian newspaper.[citation needed]
In 2016, McVicar was appointed honorary vice president of the RHS.[5] She is also an RHS Ambassador for Health & Wellbeing.[6]
