Summary
Kallstroemia grandiflora, commonly known as Arizona Poppy, is an annual herb that thrives in the desert scrub and grasslands of the Southwestern United States and northern Mexico. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and spreads 2-5 feet (0.6-1.5 meters) wide. The plant exhibits a sprawling habit with stems that radiate outward from the center. Arizona Poppy is renowned for its large, showy flowers that bloom in the summer and fall, particularly after summer monsoon rains. The blooms feature vibrant orange and yellow colors with orange corollas, and the foliage is covered with bristly trichomes that can give it a rough texture.
Arizona Poppy is valued for its drought tolerance and ability to flourish in harsh conditions, making it an excellent choice for xeriscaping and naturalistic desert gardens. It is also used to add seasonal color in rock gardens and as a ground cover in full sun areas. This plant prefers well-drained soils and requires only moderate watering once established, reflecting its adaptation to arid environments. While it is not commonly afflicted by diseases, it can occasionally suffer from root rot if overwatered. Arizona Poppy is also known for its ability to reseed and can spread readily in suitable conditions, which should be considered when planting in managed landscapes.CC BY-SA 4.0
