A 15-acre parcel adjacent to the estate was an opportunity to challenge this water-intensive ecology and create a place of relaxation and discovery in a contemporary aesthetic. Working closely with Mrs. Annenberg, the intent was to welcome visitors to the grounds at a new exhibition pavilion and invite reflection in the surrounding garden spaces.

Today the gardens at Sunnylands surprise visitors with their variety and vibrant hues, while displaying native species in bold strokes. The quiet expression of the pavilion, designed by Frederick Fisher and Partners, contrasts with the vivid botanical garden, which features 53,000 handpicked specimens from over 70 species of native and arid-adapted plants. Organic and free-flowing at the edges of the site, the lines of hardscape surfaces and planting beds take on a geometric precision as they approach the building. An adjacent event terrace and lawn offer views of the San Jacinto Mountains. More than 1.25 miles of walking trails lead visitors past the event lawn, beneath flowering palo verde desert trees, to a labyrinth garden, a performance circle, and interpretive displays of native plants.
