These were just huge. I was told by the head gardener that Mrs. Roth, the previous owner, loved begonias and they had a huge collection of them in the greenhouses. These 2 are from her collection.

I think Mrs. Roth donated Filoli to the National Trust for Historic Preservation in the 1970s. So these are very old!! They were about 5 feet in diameter. They were on either side of the grand entrance to the living room from the big foyer.
