Many plants look healthy in the spring, only to do a complete 180-degree turn by drooping and wilting away after the first long day of summer. While there are many plant species that are unable to produce flowers in the summer heat, there are plenty others that thrive in the summer sunlight and showcase fantastic flowers.
Native to the American South, as well as Mexico, blanket flower (Gaillardia pulchella) is a stunning specimen that produces brightly striped, daisy-like blooms in shades of yellow, orange, crimson and pink. The plant is highly drought tolerant and will grow well in sandy, or even disturbed, soils. Often seen growing along hot, dry roadsides, blanket flower is a low-maintenance plant that requires little care--just plant the flower in full sunlight. Avoid watering the plant too much, as blanket flower is easily susceptible to root rot.
Native to North Africa, the Middle East and parts of Europe, rose campion is a distinct-looking plant that thrives in hot weather. The plant boasts soft, pale gray foliage and brilliant hot pink flowers. Ideal for gardeners with dry, poor soil, rose campion will usually do better in limey soils than in fertile ones. The plant can handle summer heat waves with little trouble, and the plant should be grown in full sunlight for the best results.
A native of Mexico, Mexican zinnia (Zinnia haageana) is no stranger to warm weather. Mexican zinnia has thin gray-green leaves and flowers that are similar in appearance to the common zinnia. Flower colors range from white to orange and yellow depending on the cultivar. The plant is extremely tolerant of both drought and heat, and will flourish in a sunny location. Mexican zinnias should be planted in sandy, well-drained soils.
