I've had similar issues with plants in my garden during the summer months, but I've found that flowers like zinnias, marigolds, and sunflowers are quite resilient and can thrive in hot weather. They bloom beautifully and can handle strong sunlight, making them perfect for areas that get a lot of direct sun. I've also had good luck with lantanas and petunias, which are heat-tolerant and produce vibrant colors all summer long. Just make sure to water them regularly and provide some afternoon shade if possible, and they should do great in your garden.
