Poet's Shooting-Star (Dodecatheon poeticum) and help

Pretty sure of the ID of this flower. Although this example does not have the red ring at the base of the yellow ring, all the other flowers close to this one did have the red ring. See Bluffspring Photography for an example.
My help question is, "Is the background plant a form of bamboo?" I've looked several places and can't find a picture. Notice the translucent nature of the plant as well as the size as scaled by the shooting star.
This plant is growing at an elevation of about 9,950. One note is that this plant is growing near the presence of a warm spring.
Any help would be appreciated.

Thanks,
Rod

Great capture, Rod. I really like the shooting star and the translucent bamboo. I will be interested in the ID of the plant.

Background plant is a Horsetail Rush <Equisetum hyemele>. It is an ancient plant that traces it lineage back to some of the earliest vascular plants that grew on the earth.

Hi Rod,

Yes, you have a shooting star. It is always good to help with the i.d. by mentioning where you took the photo. I imagine at 9,950 ft above sea level that you must have been in the Rockies? Maybe Colorado? That would be the Southern Rocky Mountains. The Rockies are so long from north to south, they are broken up into three phytogeographic regions so you would need three wildflower books to cover the length. At least that is what Falcon Publishing did. Anyway, our home grown shooting star is Dodecatheon meadia, the one you shot is Dodecatheon pulchellum. This particular species grows in the Rockies from Alaska to Mexico. If our shooting star grew at that elevation, it would have a nose bleed.

The other plant is scouring rush, an Equisetum. There are over 15 species in the U.S. I prefer the name scouring rush for its history. The high silica content in the stem causes the plant to be very abrasive. Early settlers used this plant to scour pots and pans. I prefer to use the common name "horsetail" for those equisetums that have multiple needle-like side branches clustered along the main stem that reminds one of a horse's tail.

The equisetums are "living fossils." They were found growing over 100 million years ago, and, at up to 100 feet tall, towered over dinosaurs. Ours today are certainly a slimmed down version.

Best,
Don

Thanks Don and Daniel,
Indeed Don this photo was taken in the Colorado Rockies near Fairplay, Co.
An interesting plant. I plan to return to this location and spend some time giving this plant a more 'focused' inspection.

Thanks,
Rod
