This year's Secret Gardens include the private, residential and business gardens and landscapes of the King William Historic District. Guests can explore these unique outdoor spaces and have a chance to learn about native plants, landscape architecture, and water conservation-minded landscapes from docents.

The optional luncheon is at another secret garden, The Monty + Ivy Hall, that is full of history itself. Enjoy lunch, live acoustic Spanish guitar, Milberger's Nursery live radio show, silent auction, and a chance to meet and chat with some of the San Antonio-area's gardening experts.
