A London college specialing in horticulture, garden design, landscaping etc.
Also holds Gardening Which? trial gardens running tests on many plant species and ideas.
Consist of at least 20 individual 'gardens' each garden has its own theme eg Oriental, Tropical, Wildlife friendly, Child friendly, Low allergen, Plant collectors, Low maintenance, No watering etc etc. Great place for inspiration.
The gardens are open at weekends during the summer- just 5 mins from Crewes Hill (road with about 10 garden centres side by side) - So in all a good day out!
