What about that sweet teapot with a plant in, definitely something to try once I've found a little tea pot at a car boot sale.
How about the garden in a pond rather than a pond in a garden, fantastic. The mirrored boxes that held the cactus' reflected all the available light and looked as though they had lightbulbs in them. What a great idea.
So many alliums, on display in the floral marquee and amongst the planting in so many of the gardens. Many varieties were on display, they seem to be able to do the formal and the informal, I love them.
All in all a really good day. I will definitely go again next year, I've joined the RHS so hopefully I can go on a member only day which will make it less busy.
