Townsendia grandiflora
Also called Largeflower Ground Daisy
Townsendia grandiflora, commonly called largeflower ground-daisy, largeflower townsendia, or showy townsendia is an inconspicuous plant of the foothills of the Rocky Mountains and nearby shortgrass prairies. They are usually found in somewhat eroded or rocky areas such as the sides of hills, banks, and mesas. They are part of the Townsendia genus, which can be difficult for both amateur and expert botanists to correctly identify. A short-lived plant, they are nonetheless grown by rock garden enthusiasts for their relatively large daisy-like flowers.
Largeflower ground-daisy is grown in rock gardens, even outside its native range. It requires well-drained soil and is grown in troughs in wet climates to better control soil conditions and moisture levels. When a suitable soil is not available, they can grow in a mixture of equal parts well-composted leaves and sand. They prefer half-sun conditions where they receive direct sun for only part of the day or a west facing position with shade from the south. Propagation is by seed. Ground-daisies, including the largeflower, are not long lived plants.
Townsendia grandiflora grows in the western United States at elevations from 1300 to 2400 meters. It grows wild in five states, South Dakota, Nebraska, Wyoming, Colorado, and New Mexico. In South Dakota it has been recorded only in the southwest of the state. T. grandiflora is found in the east of Wyoming, especially towards the south and in the western areas of Nebraska. In Colorado it is found in the foothills and the high plains near the foothills of the Rocky Mountains in the eastern half of the state. In New Mexico it is primarily found in the north of the northern counties of the state, and one central county.
