OK, OK, simmer down...no need to panic!
The garden consists of two very distinct areas: the main part of the garden, between Ka'ie'ie Road (main entrance - see above) and the main house. This part is reasonably flat and about 7-8 acres or so, I think. The main house has been built right on the edge of a ridge. Coming in from the main garden it's just a few steps up to the house, and a wrap-around lanai. The other side of the house is facing a long and deep valley, and that's the other part of the garden. The property has been subdivided so I'm not sure of exactly how many acres this part consist of, but you don't see any fences after you hike down into the valley and there are many large open areas. Liloa and his wife lived in the main house. There's also a smaller house down in the valley, and their daughter and her husband, Tom, lived there. Tom was the foreman and was responsible for maintaining the garden. Liloa sold the property about 5-6 years ago, and as far as I know, he moved to New Zealand. Incidentally, in my post above where I said "Liloa had exquisite taste etc.", I was referring to the time when Liloa designed and had the garden planted. I have no reason to believe that Liloa is anything but healthy and going strong, wherever he is! And being that he is younger than me, he is still a young man!
This photo is a bit dark, because the weather was a bit unsettled with a few very brief sprinkles when we were there. Verschaffeltia splendida and other palms right in front of the main entrance to the main house.
