It's funny... I guessed all the gardens correctly before you wrote them down... I guess I've looked at a *few* pictures over the years... The lupines are a giveaway for Schreiner's, as are the enormous fields. I've seen enough of Rick Tasco's on line to recognize his planting method, as well as the background fence. Napa, I hadn't seen many pictures of their fields, but knowing where they are, the topography looked right. Mid-America, I'd heard that they had a lot of interesting trees and shrubs in addition to their Iris. All just gorgeous in their own right.
Now we need to see Keppel's and Ghios and...??
Thanks so much for posting these.
