The RHS Hampton Court Palace Garden Festival is a momentously beautiful highlight of the social season.
with a late night opening until 10.30pm on Friday 8th July and on Saturday 9th from 10am to 5.30pm, with many of the exhibitors selling plants at a reduced price from 4pm.
There is also a ferry service from Hampton Court station to the entrance that is so much fun.
I understand there are still tickets available for this wonderful show either at the box office or on their website, with RHS members receiving a discount price:
