Genus:Conoclinium

Species:greggii

Family:Asteraceae

The Palm-leaf Mistflower, a wildflower native to North America and part of the daisy family, propagates through its root system. This plant thrives in the southwestern United States, favoring gravelly soils and full sunlight, and is often found along stream banks and in areas prone to flooding.

The species name 'greggii' was designated to 23 plant species by the American Botanical Society to honor Josiah Gregg (1806-1850), whose explorations and horticultural insights were documented in his work, "Commerce of the Prairies."

This flower is an excellent choice for container gardening. When cultivated as an annual in a sheltered location, it has the potential to self-seed, providing beauty year after year.

However, it is important to note that the Palm-leaf Mistflower can become invasive, posing challenges in certain environments.
