Where to start!! Denmans gardens at Fontwell, Petworth Park, Borde Hill Gardens - 150 acres at Haywards Heath, Wakehurst at Ardingly - they also have the millennium seed bank - Highdawn at Worthing which has planting on chalky ground and Nymans Gardens at Hand Cross just off the A23 from Brighton. Finally the white garden at Sissinghurst. They are not too distant from Arundel. Have a lovely time.

Thank you Cammomile

Ive also heard this is a decent place to visit but not been there myself....will hopefully go soon.

Thanks Andy. Looks interesting and different.

There is a new garden in Arundel castle grounds. Many of the features are made of huge pieces of oak. There is an elaborate potager/vegetable garden and lots of interesting ornaments too. The grounds themselves are also interesting. There is a huge Cork Oak near the new Gardens.

Thanks Dorjac
