Mineral Wildflower Festival

Technical Name

• Collomia grandiflora

Informal Names

• Grand collomia

• Large-flowered collomia

• Big-flowered phlox

• Wild yellow phlox

Key Characteristics

• The Salmon-Cream Trumpets: It features elegant, narrowly tubular flowers that flare open into 5 distinct lobes. The color palette is highly unique, shifting from a creamy white or pale yellow to a warm, soft salmon-peach as the blooms age.

• Striking Blue Pollen: If you look closely at the center of an open blossom (especially the prominent one near the bottom of the cluster), you can see the anthers bearing a very distinctive, contrasting bright blue or lavender-blue pollen.

• Sticky, Dense Flower Heads: The flowers are crowded into a tight, rounded terminal head. The green leafy bracts directly cradling the flower cluster are covered in glandular hairs, making them distinctly sticky to the touch.

• Narrow, Smooth Leaves: The leaves are alternate, lanceolate (spear-shaped) to linear, rich green, and have completely smooth, untoothed edges.

Notable Significance

• The Phlox Family Lineage: It is a prominent native member of the Phlox family (Polemoniaceae). The genus name Collomia comes from the Greek word kolla, which means "glue," referencing the fact that the seeds become highly gelatinous and sticky when wet to help them anchor to the mountain soil.

• Pollen Color Freak of Nature: The striking blue pollen is a favorite diagnostic feature for western botanists and serves as a visual beacon for native insects.

• Pollinator Variety: Because the floral tubes are relatively deep, they are primarily pollinated by long-tongued insects, including sphinx moths, beeflies, and native solitary bees, who easily spot the pale clusters in the evening twilight.

Locations Found

• Habitat: Thrives in dry, open, or partially shaded environments with well-drained, gravelly, or sandy soils. It is highly common along dry montane ridges, open pine forests, chaparral slopes, and gravelly roadsides.

• Elevation Range: Native throughout western North America, it is incredibly common at mid-to-high elevations (between 2,000 and 9,000 feet) in the southern Cascades and Sierra Nevada. The sunny, volcanic, needle-strewn forest floors around Mineral provide its ideal habitat.
