| The flowers of Collomia grandiflora are yellow or salmon, fading to white. While all of the plants I photographed had white pollen, blue is reported as being more characteristic, at least in California. | |
| Site: Kleinschmidt Grade, Adams County, ID Date: 2012-May-25 | Photographer: Gerald C Williamson Nikon D7000 | The five corolla lobes fuse to form a trumpet-shaped corolla, giving the genus the "Trumpet Flower" common name. In the lower flower in this photo you can see three exserted stamens, as well as two included stamens. Along with size and to a lesser extent color, stamen position is among the differences with the somewhat similar Collomia linearis - Narrowleaf Mountain Trumpet. C. grandiflora will normally have at least 1 exserted stamen; all those of C. linearis are included. The style extends beyond the corolla. It is split into three stigmas, characteristic of the Phlox family. | | Click on the photo for a larger image
| Site: Kleinschmidt Grade, Adams County, ID Date: 2012-May-28 | Photographer: Gerald C Williamson Nikon D7000 | The stem and involucre bracts are quite hairy, with the involucre bracts and upper leaves usually glandular-hairy. The lower leaves may be glabrous or only slightly hairy. | | Click on the photo for a larger image
| Site: Kleinschmidt Grade, Adams County, ID Date: 2012-May-28 | Photographer: Gerald C Williamson Nikon D7000 | The alternate, lanceolate to linear leaves rise on a hairy stem to the terminal cluster of salmon to white flowers. The plant is usually unbranched, although there may occasionally be axillary stems. The plants I observed were all 12" to 15" tall. | | Click on the photo for a larger image
