Ddecatheon pulchellum, the shooting star, has unusually shaped flowers that stand out in the garden. It is not common in nurseries but it is easy to grow from seed.
The information in this post is for Dodecatheon pulchellum, but I can’t be certain the pictures are of that species. The seed was obtained from the ORG&HP society seed exchange, labeled as D. jeffreyi, but I think that name is incorrect. Dodecantheon species are all very similar, and even D. pulchellum is quite variable. The pictures may also be a garden hybrid. In any event, all Dodecatheons are great plants.
