Grand Collomia (Collomia grandiflora) is a native wildflower species found across western North America. Its range extends from British Columbia in Canada to California and parts of Mexico. Grand Collomia typically thrives in dry, open habitats such as grasslands, prairies, meadows, rocky slopes, and sandy riverbanks. It is well-adapted to arid and semi-arid regions but can also tolerate a range of soil conditions.
 
The impressive displays of tubular, peach-colored flowers typically bloom from late spring to early summer, depending on the specific location and climate. The bloom season can last for several weeks, providing a long-lasting display of color in the garden. The tubular shape and color of the flowers attracts hummingbirds, and large flower heads provide feeding platforms for bumblebees and butterflies. The relatively large seeds can also provide a source of late-season food for songbirds.
 
Grand Collomia lends itself well to various landscape functions, making it a versatile choice for both gardens and natural areas. Depending on soil depth and moisture, plants can produce one bloom at 6” on single stems in harsh conditions, or grow over 3’ tall with branching flowers in deep loam soils. Sowing in fall (up to 1/4" deep) and overwintering seedlings will provide larger plants the following year, but early spring sowing is equally successful.
