Marigolds are a beautiful, yet underrated, flower. These sunshiney blooms are a brightening addition to any garden, where they add a touch of elevated warmth. If you need any more proof, look no further than Olivia Newton-John's Malibu, California garden from the 1970s.
An archival image from 1976 shows the Grease actress posing by her poolside with her three dogs, surrounded by some of the best pool planting ideas we've ever seen. Her plants sprout from beds, planters, and raised stone beds in the background. Marigolds (seeds available at Amazon) and zinnias feature prominently. It feels like a celebration of florals that dominates her pool design.
