She's quite and old lady, I met her on Sunday. Her daughter helps out a little, but it's getting too much for both and the property is quite remote which makes it difficult for volunteers. Quite sad.
I find these places through gardening magazines and word of mouth and try to visit as many as I can. I'm a busy guy though and it's difficult sometimes. I'm glad I made the time to see this one though, and yeah, it was a great day for it.
I hope you manage to get to some of these gardens around your area sometime; I think you'll enjoy it.
