I have been to numerous English gardens, but Highgrove is so breath-takingly beautiful!
I'm very glad that it is open for the public, I might indeed visit it one day!
I do admire Charles' passion for gardening and think that gardening should become -- once again -- a part of everyone's lives. Kids nowdays have no idea where food comes from. I agree, and I wish that everybody could have a parcel of land to do that. Or that more areas could be used, made available for community gardens.
Community gardens are becoming more common in my area. Also, container gardening can be done in an urban setting. It's amazing how much food can be grown from one vine [squash, I'm lookin' at you].
