Postcard from Bayou Bend House & Garden

My Aunt and Uncle sent a postcard (this time for the grown-ups) from Bayou Bend House & Garden in Houston, TX. I'm not a big fan of Texas, but this looks like a nice place to visit. The back of the card says:

"A 28-room Greek Revival-inspired mansion is the crown jewel of Bayou Bend. Inside are exquisite 18th and 19th century furnishings, glass, silver, and art. Outside are more than a dozen acres of lush blooming garden."

Looking at the map, the garden's design from the postcard is clearly visible (just look down and to the right from the push pin-the push pin appears to be their parking lot).
