The Duke Farms is a huge property and features diverse landscapes. They don't have any formal gardens to speak of. However they do have an Orchid Conservatory and several lawns have been converted to wildflower meadows.
Both the Wildflowers and Orchids should be in bloom at the time that we'll be there.
The Duke Farms is reasonably close and is about an hour's drive away from Ramsey.
The Gardens opens at 8:30 a.m. so I'd suggest we meetup at the Mahwah Sheraton at 7:00 a.m. and car pool to the gardens.
We should plan on photographing the wildflowers in the sweet morning light and when the light begins to turn harsh, we can go inside the conservatory and photograph the Orchids.
The Duke Farms seems like a perfect place for us to practice the macro techniques that we learned from Mike Moats and Roman K.
