Frogmore House is a country house in Berkshire owned by the Crown Estates. It was built during the reign of Charles II by one Hugh May. A story that May asked the king "Your Majesty, may I build a house in the grounds of WIndsor Castle?" and he replied "Yes, Hugh May" remains unconfirmed, probably because I just made it up.
It became a royal residence in 1692, when it was bought by Mad King George's wife, Queen Charlotte. The main thing to know about Queen Charlotte is that she was really, really into botany. This is reflected not only in the magnificent gardens, but in the decor of the house. To call it "floral-patterned" would be a massive understatement. The wallpaper alone would give a person hay fever.
The gardens are home to over 4000 trees and shrubs, including tulip trees and redwoods. There is an 18th century summerhouse designed to look like a gothic ruin, and a teahouse made for Queen Victoria.
Frogmore House is home to part of the Royal Collection. Again, many of the works have a botanical theme, including artificial flower arrangements, and paintings by botanical artist Mary Moser.
Frogmore House is open to the public only in August. Bookings must be made in advance, and the minimum party size is 15. Details can be found here.
