1. Alleyn Park
"This charming garden centre tucked away in West Dulwich may be small, but the plants are well chosen, the staff extremely helpful, and the collection of gifts and gardeners' accessories delightful," says Anna Rose. "Also, if you sign up to the mailing list, a regular newsletter of inspiring hints arrives in your inbox."
Where: 77 Hall Road, London, SE21 8ES (020 8670 7788; alleynpark.co.uk)
2. Wisley Plant Centre RHS

"Magnificent magnolias and fabulous ferns – choose from 9,000 different delights and next door is the best gardening bookstore in the world."

4. World's End Nurseries
Standing on an acre of land, the oldest of Chelsea's nurseries occupies a site used for hundreds of years as a thriving garden, says Dorothy. "Today it offers a calm and slightly quirky green oasis at the end of the bustling King's Road in London. Pick your way through the eclectic mix of plants and pots artfully arranged around the meandering pathways, making it more like a visit to a secret garden than a walk through a garden centre. Indoor and outdoor plants fight for space with garden statuary, planters, benches and even the odd gazebo."

5. RHS Hyde Hall
Expansive is the feeling you get from Hyde Hall from the moment you pull up in the newly landscaped car park, says Dorothy. Set atop a hill, the house and gardens are very exposed and the planting is carefully selected to ensure that the "right plant right place" principles are applied and the plants thrive. Using this experience, the nursery is stocked with an excellent selection of high-quality plants suitable for drier, poorer soils. "Top it all with a delicious light lunch or tea in the tea garden and make it a day out."
