Floribundas like Frida Kahlo do best with at least six hours of sunlight each day, and fewer sunny hours will result in fewer blooms. However, intense afternoon sun can damage the blooms, especially in very hot climates. For best results in hot climates, roses should be planted in a spot where they receive sun in the morning and a bit of shade at the height of the day, such as a foundation planting on the eastern side of a building or fence.
